Administrators must enable the “Display FDMI Host Name” configuration via the configure CLI. fspfShow and lsdbShow CLI Enhancement FOS v7.3 changes fspfShow and lsdbShow CLI output to omit all zero value to be listed in port bitmap values. Device Probing and Update on ALPA 0xC0 and 0x40 FOS v7.3 enhances FCP probing for devices connected to a port with ALPA 0xC0 and 0x40 to obtain the device information for NS entry. For base devices that logged in with ALPA 0xC0 and 0x40, FOS v7.3 provides the ability to update NS entries when these base devices perform logout. Administrators can turn on this update mode to ensure NS and login database consistency with “F-port Device Update Mode” option under the “Fabric parameters” section of the configure CLI. This option can only be changed when a switch is disabled. NPIV Base Device Logout Enhancements FOS v7.3 enhances NPIV by allowing NPIV devices remain logged in on a port to a fabric when the base device on the same port performs a logout. Administrator can configure this feature via the portCfgFlogiLogout CLI. Fabric OS v7.3.0 Release Notes v2.0 Page 14 of 114 fosExec Remote Execution FOS v7.3 adds the ability to execute a FOS CLI command via fosExec CLI on a remote domain in the fabric. Administrators can enable this capability to execute CLI commands on multiple switches from a single switch in a fabric. CS_CTL QoS Enhancements FOS v7.3 enhances CS_CTL based QoS feature by reporting the CS_CTL auto mode in responses to device FLOGI, FDISC, and PLOGI requests. bottleneckMon CLI Change FOS v7.3 deprecates the back-end credit recovery options in the bottleneckMon CLI. These options are supported via the existing creditRecovMode CLI. Maximum Auto Speed Negotiation FOS v7.3 allows configuring a maximum speed for port auto speed negotiation with CLI portcfgspeed (via -m option). Administrators can use this to control the maximum speed a device is allowed to join a fabric but still allow port speed to be auto negotiated. Back-end credit recovery on FX8-24 blade FOS v7.3 enhances back-end credit loss detection and recovery to back-end links on FX8-24 with the existing CLI command creditRecovMode. aptPolicy change FOS v7.3 deprecates AP policy related configuration from the CLI command aptPolicy.

Customers that wish to have these capabilities without purchasing the license are required to upgrade to FOS v7.2 or later. Brocade 6520 does not require the Adaptive Networking with QoS license to enable the capabilities associated with this license. These capabilities are included by default on the Brocade 6520. Server Application Optimization — When deployed with Brocade Server Adapters, this license optimizes overall application performance for physical servers and virtual machines by extending virtual channels to the server infrastructure. Application specific traffic flows can be configured, prioritized, and optimized throughout the entire data center infrastructure. This license is not supported on the Brocade 8000. Note : With FOS v7.2, Server Application Optimization license has become part of the base FOS firmware, and features under this license no longer require the license to be installed. Customers that wish to have these capabilities without purchasing the license are required to upgrade to FOS v7.2 or later. Brocade 6520 does not require the SAO license to enable the capabilities associated with this license. These capabilities are included by default on the Brocade 6520. Integrated Routing— This license allows any port in a DCX 8510-8, DCX 8510-4, Brocade 6510, Brocade 6520, DCX-4S, DCX, 5300, 5100, 7800, 7840, or Brocade Encryption Switch to be configured as an Ex_port or VEx_port (on some platforms) supporting Fibre Channel Routing. Encryption Performance Upgrade — This license provides additional encryption processing power. For the Brocade Encryption Switch or a DCX/DCX-4S/DCX 8510-8/DCX 8510-4, the Encryption Performance License can be installed to enable full encryption processing power on the BES or on all FS8-18 blades installed in a DCX/DCX-4S/DCX 8510-8/DCX 8510-4 chassis.

DataFort Compatibility License is also required on the Brocade Encryption Switch or DCX/DCX-4S/DCX 8510- 8/DCX 8510-4 Backbone with FS8-18 Encryption Blade(s) installed to write and encrypt the disk and tape LUNs in NetApp DataFort Mode (Metadata and Encryption Algorithm) so that DataFort can read and decrypt these LUNs. DataFort Mode tape encryption and compression is supported beginning with the FOS v6.2.0 release on DCX platforms. Availability of the DataFort Compatibility license is limited; contact your vendor for details. Advanced Extension – This license enables two advanced extension features: FCIP Trunking and Adaptive Rate Limiting. The FCIP Trunking feature allows multiple IP source and destination address pairs (defined as FCIP Circuits) via multiple 1GbE or 10GbE interfaces to provide a high bandwidth FCIP tunnel and failover resiliency. In addition, each FCIP circuit supports four QoS classes (Class-F, High, Medium and Low Priority), each as a TCP connection. The Adaptive Rate Limiting feature provides a minimum bandwidth guarantee for each tunnel with full utilization of the available network bandwidth without impacting throughput performance under high traffic load. This license is available on the 7800, 7840, and the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 for the FX8-24 on an individual slot basis. Fabric OS v7.3.0 Release Notes v2.0 Page 17 of 114 10GbE FCIP/10G Fibre Channel – This license enables the two 10GbE ports on the FX8-24 and/or the 10G FC capability on FC16-xx blade ports supported on DCX 8510 platforms except for the FC16-64 blade. On the Brocade 6510, Brocade 6520 this license enables 10G FC ports. This license is not applicable to Brocade 7840 or Brocade 6505. On FX8-24: With this license installed and assigned to a slot with an FX8-24 blade, two additional operating modes (in addition to 10 1GbE ports mode) can be selected: 10 1GbE ports and 1 10GbE port, or 2 10GbE ports On FC16-xx: Enables 10G FC capability on an FC16-xx blade in a slot that has this license On Brocade 6510, Brocade 6520: Enables 10G FC capability on Brocade 6510 and Brocade 6520. This license is available on the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 on an individual slot basis. Advanced FICON Acceleration – This licensed feature uses specialized data management techniques and automated intelligence to accelerate FICON tape read and write and IBM Global Mirror data replication operations over distance, while maintaining the integrity of command and acknowledgement sequences. This license is available on the 7800 and the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 for the FX8-24 on an individual slot basis. 7800 Port Upgrade – This license allows a Brocade 7800 to enable 16 FC ports (instead of the base four ports) and six GbE ports (instead of the base two ports). This license is also required to enable additional FCIP tunnels and also for advanced capabilities like tape read/write pipelining. ICL 16-link, or Inter Chassis Links -- This license provides dedicated high-bandwidth links between two Brocade DCX chassis, without consuming valuable front-end 8Gb ports. Each chassis must have the 16-link ICL license installed in order to enable the full 16-link ICL connections. (Available on the DCX only.) ICL 8-Link – This license activates all eight links on ICL ports on a DCX-4S chassis or half of the ICL bandwidth for each ICL port on the DCX platform by enabling only eight links out of the sixteen links available. This allows users to purchase half the bandwidth of DCX ICL ports initially and upgrade with an additional 8-link license to utilize the full ICL bandwidth at a later time. This license is also useful for environments that wish to create ICL connections between a DCX and a DCX-4S, the latter of which cannot support more than 8 links on an ICL port. Available on the DCX-4S and DCX platforms only. ICL POD License – This license activates ICL ports on core blades of DCX 8510 platforms. An ICL 1st POD license only enables half of the ICL ports on CR16-8 core blades of DCX 8510-8 or all of the ICL ports on CR16-4 core blades on DCX 8510-4. An ICL 2nd POD license enables all ICL ports on CR16-8 core blades on a DCX 8510-8 platform. (The ICL 2 nd POD license does not apply to the DCX 8510-4.) Enterprise ICL (EICL) License – The EICL license is required on a Brocade DCX 8510 chassis when that chassis is connected to four or more Brocade DCX 8510 chassis via ICLs. Note that this license requirement does not depend upon the total number of DCX 8510 chassis that exist in a fabric, but only on the number of other chassis connected to a DCX 8510 via ICLs. This license is recognized/displayed when operating with FOS v7.0.1 but enforced with FOS v7.1.0 or later. Note: The EICL license supports a maximum of nine DCX 8510 chassis connected in a full mesh topology or up to twelve DCX 8510 chassis connected in a core-edge topology. Refer to the Brocade SAN Scalability Guidelines document for additional information. WAN Rate Upgrade 1 License – The WAN Rate Upgrade 1 license provides the additional WAN throughput up to 10 Gbps on Brocade 7840. The base configuration of Brocade 7840 without the WAN Rate Upgrade 1 license provides WAN throughput up to 5 Gbps. Fabric OS v7.3.0 Release Notes v2.0 Page 18 of 114 WAN Rate Upgrade 2 License – The WAN Rate Upgrade 2 license provides unlimited WAN throughput (other than the hardware limit) on Brocade 7840. The WAN Rate Upgrade 2 licenses also enable the use of two 40GbE ports on Brocade 7840. The 40GbE ports cannot be configured without the WAN Rate Upgrade 2 license. A WAN Rate Upgrade 1 license must be installed on a Brocade 7840 before a WAN Rate Upgrade 2 license is installed. A WAN Rate Upgrade 1 license cannot be removed before the WAN Rate Upgrade 2 license has been removed. Note: The WAN Rate Upgrade 1 and WAN Rate Upgrade 2 licenses apply only to Brocade 7840. They control the aggregate bandwith for all tunnels on a Brocade 7840. The entire capacity controlled by the licenses can be assigned to a single tunnel subject to hardware limitation, or a portion of the capacity can be assigned to multiple tunnels. The total bandwidth aggregated for all tunnels should not exceed the limits established by the licenses. Fabric OS v7.3.0 Release Notes v2.0 Page 19 of 114 Temporary License Support The following licenses are available in FOS v7.3 as Universal Temporary or regular temporary licenses: Fabric (E_Port) license Extended Fabric license Trunking license High Performance Extension license Advanced Performance Monitoring license Fabric Watch license Integrated Routing license Advanced Extension license Advanced FICON Acceleration license 10GbE FCIP/10GFibre Channel license FICON Management Server (CUP) Enterprise ICL license Fabric Vision license Note: Temporary Licenses for features available on a per slot basis enable the feature for any and all slots in the chassis.

When 2+2 power supply combination is used, the users are advised to configure the Fabric Watch setting for switch marginal state to be two power supplies. Users can use the CLI switchstatuspolicyset to configure this value if the current value is set to zero. In FOS v7.0.x, the default setting for the marginal state due to missing power supplies is incorrectly set to zero, which will prevent Fabric Watch from generating notifications when the switch enters the marginal state due to missing power supplies 2. Power supply requirements for a 512 port configuration without the use of ICLs will be reduced to two (1+1) in a future 7.3.0x patch release.

Limits may be increased once further testing has been completed, even after the release of Fabric OS. For current scalability limits for Fabric OS, refer to the Brocade Scalability Guidelines document, available under the Technology and Architecture Resources section at http://www.brocade.com/compatibility Other Important Notes and Recommendations Note: Please note that most content in this section is primarily applicable to FOS v7.2.1a firmware and has not been completely updated for FOS v7.3.0. Contents of this section may or may not be entirely applicable to FOS v7.3.0 firmware. Adaptive Networking/Flow-Based QoS Prioritization Any 8G or 4G FC platform running FOS v6.2.2e or lower version of firmware cannot form an E-port with a 16G FC platform when Adaptive Networking QoS is enabled at both ends of the ISL. Users must disable QoS at either end of the ISL in order to successfully form an E-port under this condition. Users can disable QoS via portcfgQos --disable command. Please consult Fabric OS Command Reference manual for details related to portcfgQoS command. When using QoS in a fabric with 4G ports or switches, FOS v6.2.2 or later must be installed on all 4G products in order to pass QoS info. E_Ports from the DCX to other switches must come up AFTER 6.2.2 is running on those switches. When FOS is upgraded from v7.1.x to v7.2.0 or later: If the Adaptive Networking license was NOT installed in v7.1.x, all ports will have QOS disabled following the firmware upgrade and links will come up in normal mode. If the Adaptive Networking license was installed in v7.1.x, there will be no change in port QOS mode following the upgrade. Fabric OS v7.3.0 Release Notes v2.0 Page 41 of 114 If the remote port supports QOS and QOS is not explicitly disabled on the local or remote port, the link will come up in QOS mode. Otherwise, the link will come up in normal mode. If FOS v7.2 or later is factory installed (or net installed), Adaptive Networking features are always available. This matches the behavior of the Brocade 6520 and all products shipping with prior versions of FOS and with the Adaptive Networking license factory installed. Ports will come up in AE mode by default If the remote port supports QOS and is not explicitly disabled, the link will come up in QOS mode. Otherwise, the link will come up in normal mode. Access Gateway Users who want to utilize Access Gateway’s Device-based mapping feature in the ESX environments are encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices.

Brocade HBA/Adapter Compatibility Brocade HBA/Adapter should be using driver version 2.3.0.2 or later when attached to 16G ports on Brocade switches. D_Port The 16Gb QSFP optics used in FC16-64 blade do not support electrical loopback and optical loopback tests. Support is limited to: o Link traffic tests across the 16Gb QSFPs o Roundtrip link latency measurements o Link distance measurements for links that are longer than 100 meter Edge Hold Time Edge Hold Time (EHT) default settings for FOS v7.x have changed from those in some FOS v6.4.x releases. The following table shows the Default EHT value based on different FOS release levels originally installed at the factory: Factory Installed Version of FOS Default EHT Value FOS v7.X 220 ms FOS v6.4.3x 500 ms FOS v6.4.2x 500 ms FOS v6.4.1x 220 ms Fabric OS v7.3.0 Release Notes v2.0 Page 42 of 114 FOS v6.4.0x 500 ms Any version prior to FOS v6.4.0 500 ms Gen 5 platforms and blades are capable of setting an EHT value on an individual port basis. On 8G platforms EHT is set on an ASIC-wide basis, meaning all ports on a common ASIC will have the same EHT setting. Extra care should be given when configuring EHT on 8G platforms or Gen 5 platforms with 8G blades to ensure E_Ports are configured with an appropriate Hold Time setting. When using Virtual Fabrics and creating a new Logical Switch when running FOS v7.1.0 or later, the default EHT setting for the new Logical Switch will be the FOS default value of 220ms. However, with FOS v7.1.0 and later, each Logical Switch can be configured with a unique EHT setting that is independent of other Logical Switches and the Default Switch. Any Gen 5 ports (Condor3 based) assigned to that Logical Switch will be configured with that Logical Switch’s EHT setting. Any 8G ports (Condor2 based) will continue to share the EHT value configured for the Default Switch. For more information on EHT behaviors and recommendations, refer to the Brocade SAN Fabric Resiliency Best Practices v2.0 document available on www.brocade.com. Encryption Behavior for the Brocade Encryption Switch (BES) and FS8-18 SafeNet’s KeySecure hosting NetApp’s LKM (SSKM) is supported for data encryption operations with SSKM operating in PVM mode. Please see SSKM documentation for operating in PVM mode for details. Operation in HVM mode is not supported RASlog SPC-3005 with error 34 may be seen if the link key used by a BES/FS8-18 is re- established. Please refer to the LKM/SSKM Encryption Admin Guide for the workaround. Also, please ensure that two (2) SSKM’s are present in the deployment for workaround to be performed. For crypto tape operations, please ensure to use Emulex FC HBA firmware/drivers 2.82A4/7.2.50.007 or higher. Use of lower level firmware/drivers may result in hosts not being able to access their tape LUNs through a crypto target container. Adding of 3PAR Session/Enclosure LUNs to CTCs is now supported. Session/Enclosure LUNs (LUN 0xFE) used by 3PAR InServ arrays must be added to CryptoTarget (CTC) containers with LUN state set to “cleartext”, encryption policy set to “cleartext”. BES/FS8-18 will not perform any explicit enforcement of this requirement. The Brocade Encryption switch and FS8-18 blade do not support QoS. When using encryption or Frame Redirection, participating flows should not be included in QoS Zones. The RSA DPM Appliance SW v3.2 is supported. The procedure for setting up the DPM Appliance with BES or a DCX/DCX-4S/DCX 8510 with FS8-18 blades is located in the Encryption Admin Guide. Support for registering a 2nd DPM Appliance on BES/FS8-18 is blocked. If the DPM Appliances are clustered, then the virtual IP address hosted by a 3rd party IP load balancer for the DPM Cluster must be registered on BES/FS8-18 in the primary slot for Key Vault IP. With Windows and Veritas Volume Manager/Veritas Dynamic Multipathing, when LUN sizes less than 400MB are presented to BES for encryption, a host panic may occur and this configuration is not supported in the FOS v6.3.1 or later release. Hot Code Load from FOS v7.2.x to FOS v7.3 is supported. Cryptographic operations and I/O will be disrupted but other layer 2 FC traffic will not be disrupted. When disk and tape CTCs are hosted on the same encryption engine, re-keying cannot be done while tape backup or restore operations are running. Re-keying operations must be scheduled at a time that Fabric OS v7.3.0 Release Notes v2.0 Page 43 of 114 does not conflict with normal tape I/O operations. The LUNs should not be configured with auto rekey option when single EE has disk and tape CTCs. Gatekeeper LUNs used by SYMAPI on the host for configuring SRDF/TF using in-band management must be added to their containers with LUN state as “cleartext”, encryption policy as “cleartext” and without “-newLUN” option. FOS7.2 and later supports KMIP key vault type for Thales e-Security Key Authority SW v4.0.0 KMIP servers. Please refer to the KMIP Encryption Admin Guide for more details. Replication feature from Thales e-Security Key Authority KMIP server is not supported with BES/FS8-18. In FOS 7.1.0 or later the encryption FPGA has been upgraded to include parity protection of lookup memory (ROM) within the AES engine. This change enhances parity error detection capability of the FPGA. BES/FS8-18 will reject the SCSI commands WRITE SAME, ATS(Compare and Write/Vendor Specific opcode 0xF1) and EXTENDED COPY, which are related to VAAI (vStorage APIs for Array Integration) hardware acceleration in vSphere 4.1/5.x. This will result in non-VAAI methods of data transfer for the underlying arrays, and may affect the performance of VM related operations. VMware VMFS5 uses ATS commands with arrays that support ATS. BES/FS8-18 does not support this command set. Use of a workaround procedure is required in order to configure encryption in a VMFS 5 environment. Please refer to Brocade Tech Note “Deployment Options for VMware VMFS-5 with Brocade Encryption” for details. XIV storage arrays that have been upgraded to firmware 11.2x or later required to support encryption on thin provisioned LUNs will report all XIV data LUNs as TP=Yes. FCIP (Brocade 7800 and FX8-24) Any firmware activation will disrupt I/O traffic on FCIP links. Latency measurements supported on FCIP Tunnels: o 1GbE & 10GbE - 200ms round trip time and 1% loss. After inserting a 4G SFP in GE ports of an FX8-24 blade or 7800 switch, sometimes “sfpshow” output might display “Cannot read serial data!”. Removing and re-inserting the SFP should resolve this issue. It is recommended that users perform sfpshow immediately after inserting the SFP and ensure SFP is seated properly before connecting the cables. When running FOS v7.2.0 or later, if the new FCIP Circuit Group feature is configured on any FCIP Circuits, a downgrade operation to pre-FOS v7.2.0 will be blocked until the feature is removed from the FCIP configuration(s). FCIP (Brocade 7840) Brocade 7840 does not support FCIP connection to Brocade 7800 or FX8-24. FOS v7.3.0 does not support non-disruptive firmware download in one-to-many sites configuration. FOS v7.3.0 does not support concurrent non-disruptive firmware download. FOS v7.3.0 does not support non-disruptive firmware download on the 20VE Mode. FOS v7.3.0 does not support 10G speed on the 24 16G FC ports on Brocade 7840. FOS v7.3.0 does not support VEX port on Brocade 7840. FOS v7.3.0 does not support base switch on Brocade 7840. Fabric OS v7.3.0 Release Notes v2.0 Page 44 of 114 FOS v7.3.0 does not support credit recovery on BI ports on Brocade 7840. Running offline diagnostic tests results in FCIP tunnels down. Reboot the switch after offline diagnostic tests to recover the tunnels. FCoE/DCB/CEE (FCOE10-24) When upgrading a DCX/DCX-4S with one or more FCOE10-24 blades from FOS v6.x to FOS v7.0.0 or later, the user should carefully review Chapter 5 of the FOS v7.0.0 Converged Enhanced Ethernet Administrator’s Guide. Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience momentary traffic disruption during HA failover. Hot plugging a CP with firmware level less than FOS v6.3.0 into a DCX or DCX-4S with an active FCOE10-24 blade will result in the new standby CP not coming up. When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is processed normally. The host should be configured not to send VLAN tagged traffic on the switch’s native VLAN. When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured native VLAN are dropped. The Converged Network Adapter (CNA) may lose connectivity to the FCOE10-24 if the CNA interface is toggled repeatedly over time. This issue is related to the CNA and rebooting the CNA restores connectivity. The FCOE10-24 support only one CEE map on all interfaces connected to CNAs. Additionally, CEE map is not recommended for use with non-FCoE traffic. QoS commands are recommended for interfaces carrying non-FCoE traffic. Before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, if the CEE map “default” value already exists, the same “default” value is preserved after upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later. However, if the CEE map “default” is not configured before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, then after upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the following CEE map “default” will be created automatically: cee-map default priority-group-table 1 weight 40 pfc priority-group-table 2 weight 60 priority-table 2 2 2 1 2 2 2 2 When upgrading from FOS v6.3.x or v6.4.x to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the CEE start up configuration dcf.conf file will be incompatible with the FCoE provisioning changes implemented in v6.4.1_fcoe and later releases. Users can save the dcf.conf file as a backup and apply it once the firmware upgrade is completed to get the DCX/DCX-4S to the same startup configuration as in the older release. It is recommended that Spanning Tree Protocol and its variants be disabled on CEE interfaces that are connected to an FCoE device. The Fabric Provided MAC Address (FPMA) and the Fibre Channel Identifier (FCID) assigned to a VN_Port cannot be associated with any single front-end CEE port on which the FLOGI was received. LLDP neighbor information may be released before the timer expires when DCBX is enabled on a CEE interface. This occurs only when the CEE interface state changes from active to any other state. When the DCBX is not enabled, the neighbor information is not released until the timer expires, irrespective of the interface state. Fabric OS v7.3.0 Release Notes v2.0 Page 45 of 114 The FCoE login group name should be unique in a fabric-wide FCoE login management configuration. If there is a login group name conflict, the merge logic would rename the login group by including the last three bytes of the switch WWN in the login group name. As long as the OUI of the switch WWNs are identical this merge logic guarantees uniqueness in any modified login group name (switches with the same OUI will have unique last 3 bytes in WWN). However, if the participating switches have different OUIs but identical last three bytes in the switch WWNs, then the merge logic will fail to guarantee uniqueness of login group names. This will result in one of the login groups being dropped from the configuration. This means, no device can login to the login group that is dropped as a result of this name conflict. Users must create a new login group with a non-conflicting name to allow device logins. Ethernet switch services must be explicitly enabled using the command “fosconfig –enable ethsw” before powering on an FCOE10-24 blade. Failure to do so will cause the blade to be faulted (fault 9). Users can enable ethsw after upgrading firmware without FC traffic interruption. Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.4.1_fcoe1 to FOS v7.0 or later will be non-disruptive to FCoE traffic through FCOE10-24 blades and FC traffic. Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.3.x, v6.4.x, and v6.4.1_fcoe to FOS v7.0 or later will be disruptive to any traffic through the FCOE10-24 blades. When rebooting a DCX or DCX-4S with an FCOE10-24 blade, Qlogic CNA and LSAN zoning, the switch will become very unresponsive for a period of time. This is due to the CNA sending excessive MS queries to the switch. The FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the FCOE10-24, and you delete a large number of v-ports with HCM, some of the v-ports may not appear to be deleted. To correct this, disable and re-enable FCoE with the following CLI commands: switch:admin>fcoe –disable slot/port switch:admin>fcoe --enable slot/port When a FCOE10-24 blade is powered off during configuration replay, the interface specific configuration won’t get applied. Later when FCOE10-24 blade is powered on, all physical interfaces will come up with default configurations. User can execute “copy startup-config running-config” command to apply the new configuration after powering on the FCOE10-24 blade. When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN. User has to reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN. FOS v7.3 adds the support of FCOE10-24 blade in DCX 8510-8 chassis with following limitations: o Only one FCOE10-24 blade is supported at the fixed slot 1 position. Inserting the blade into other slot positions, however, will not fault the blade. o An FCOE10-24 blade can co-exist with FC16-32 and FC8-32E blades only in a DCX 8510-8 chassis. o Only supports FCoE direct attach. o Layer2 Ethernet traffic is not supported. o If an FCoE10-24 blade is inserted into a DCX 8510-8 chassis, it is required to reboot the chassis or slot poweroff/poweron core blades. A chassis reboot or slot poweroff/poweron core blades must also be performed if the FCoE10-24 blade is removed and replaced with another blade type. FCR and Integrated Routing With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs unique. VEX edge to VEX edge device sharing will not be supported. Fabric OS v7.3.0 Release Notes v2.0 Page 46 of 114 Forward Error Correction (FEC) Though FEC capability is generally supported on Condor3 (16G capable FC) ports when operating at either 10G or 16G speed, it is not supported with all DWDM links. Hence FEC may need to be disabled on Condor3 ports when using DWDM links with some vendors by using portCfgFec command. Failure to disable FEC on these DWDM links may result in link failure during port bring up. Refer to the Brocade Fabric OS 7.x Compatibility Matrix for supported DWDM equipment and restrictions on FEC use. FICON For FICON qualified releases, please refer to the Appendix: Additional Considerations for FICON Environments section for details and notes on deployment in FICON environments. (This appendix is only included for releases that have completed FICON qualification). FL_Port (Loop) Support FL_Port is not supported on FC16-32, FC16-48, FC16-64, FC8-32E, FC8-48E, Brocade 6510, Brocade 6505, Brocade 6520, or Brocade 7840. The FC8-48 and FC8-64 blade support attachment of loop devices. Virtual Fabrics must be enabled on the chassis and loop devices may only be attached to ports on a 48-port or 64-port blade assigned to a non-Default Logical Switch operating with the default 10- bit addressing mode (they may not be in the default Logical Switch). A maximum of 144 ports may be used for connectivity to loop devices in a single Logical Switch within a chassis in 10-bit dynamic area mode on DCX-4S. A maximum of 112 ports may be used for connectivity to loop devices in a single Logical Switch within a chassis in 10-bit dynamic area mode on DCX. Loop devices continue to be supported when attached to ports on the FC8-16, FC8-32 with no new restrictions. Flow Vision Users must not specify well known FC addresses, domain controller addresses or CUP Port ID (in FMS mode) for either the source or the destination device field while defining flows. Flow Vision does not support port swap. Users must not create flows on ports that are already swapped and users must not swap the ports on which the flows are currently defined. After a HA reboot, a flow generator flow can be created if the source or the destination port is F-Port. But traffic will not be initiated. Toggling the port will enforce the restriction again to simulated ports. Flow Monitor does not support flows with defined LUN parameters on ingress ports on 8G platforms. ICLs on DCX/DCX-4S If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the 16- link license will report enc_out errors. The errors are harmless, but will continue to increment. These errors will not be reported if a DCX with a 16-link license is connected to a DCX-4S with only 8-link ICL ports. If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors. Native Connectivity (M-EOS interoperability) A switch running FOS v7.0 or later cannot form E-port connectivity with any M-EOS platform. Fabric OS v7.3.0 Release Notes v2.0 Page 47 of 114 Platform running FOS v7.1 or later does not support EX port configuration in Interopmode 2 or Interopmode 3. Device sharing between a switch running FOS v7.1 or later and McDATA fabrics is allowed via Integrated Routing platforms using FOS v7.0.x (or earlier) firmware. Port Initialization Users may observe that a port is in “Port Throttled” state when an F_Port is being initialized. This is mostly an informational message that is shown in switchshow output indicating systematic initialization of F_Ports. However, a port may remain in “Port Throttled” state for an extended period of time and may never come online if it fails to negotiate speed successfully with the neighboring port. Users are advised to check the speed setting of the neighboring switch port to determine the cause of the speed negotiation failure. Example Output: 74 9 10 36ed40 id N8 In_Sync FC Disabled (Port Throttled) Port Mirroring Port Mirroring is not supported on the Brocade 7800. Port Statistics On 16G capable ports, the enc_in (number of encoding errors inside of frames) and enc_out (number of encoding errors outside of frames) counters will not be updated when a port is operating at either 10G or 16G speed. This is due to the different encoding scheme used at 10G and 16G speeds when compared to 8G/4G/2G speeds. Because of this, Fabric Watch alerts and Port Fencing based on ITW (Invalid Transmission Word) thresholds will not function as these enc_in and enc_out counters will not be incremented when operating at either 10G or 16G (ITW is computed based on enc_in and enc_out counters). Also any CLI or GUI that displays enc_in and enc_out counters will show no incrementing of these counters when a port is operating at either 10G or 16G. Both enc_in and enc_out counters contain valid information when a Condor3-based port is operating at speeds other than 10G and 16G. Virtual Fabrics When creating Logical Fabrics that include switches that are not Virtual Fabrics capable, it is possible to have two Logical Switches with different FIDs in the same fabric connected via a VF incapable switch. Extra caution should be used to verify the FIDs match for all switches in the same Logical Fabric. A switch with Virtual Fabrics enabled may not participate in a fabric that is using Password Database distribution or Administrative Domains. The Virtual Fabrics feature must be disabled prior to deploying in a fabric using these features. ISL R_RDY mode is not supported in a base switch with FOS version 7.0 or higher. WebTools WebTools since FOS v7.1.0 has a “SupportSave” interface. It only collects, however, information specifics to WebTools. It does not contain the same information as collected by supportSave initiated through CLI or Brocade Network Advisor. When launching WebTools on a computer without Internet access, it could take up to 5 minutes to complete because the certificate revocation check performed for the WebTools application takes time Fabric OS v7.3.0 Release Notes v2.0 Page 48 of 114 to timeout. Users can turn off the certification revocation check on the Java control panel as a workaround. FOS v7.3.0 is qualified and supported with Oracle JRE 1.7.0 update 60. When launching Web tools directly using the browser for FOS 7.3.0, ensure that Oracle JRE update 1.7u60 is installed in that machine. WebTools can be launched from the local client of Brocade Network Advisor installed on Windows OS. Launching WebTools from local client of Brocade Network Advisor installed on Linux OS will fail due to the expiration check with JRE 1.7 update 51. As a workaround for this issue on Linux, please do the following changes in the Brocade Network Advisor installed computer. 1. Add following lines in <User Home>/.java/deployment/deployment.properties file deployment.expiration.check.enabled=false For example, if the user is root then the absolute path of this file is as below /root/.java/deployment/deployment.properties 2. Launch the java control panel using below command and click on Ok button <Network Advisor Home>\jre\bin\jcontrol Please refer to Brocade Network Advisor release notes for more details. In addition, users must check the “Enable Java content in the browser” box under the Security tab of Java Control Console to allow launching WebTools from BNA server clients. Zoning There are limitations to zoning operations that can be performed from a FOS v6.x switch that is in the same fabric as a FOS v7.0 or later switch if the FOS v6.x switch is not running the recommended firmware version. Please see Fabric OS Interoperability section for details. Miscellaneous Users must also keep the RADIUS accounting port (Authentication Port+1) open in the firewall to ensure proper working of the RADIUS authentication. Using a Windows anonymous FTP server for supportsave collection: When using anonymous ftp, to avoid long delays or failure of simultaneous supportsave collections when AP blades are present in a director chassis, the number of unlimited anonymous users for a Windows FTP server should be configured as follows: Number of anonymous FTP connections = (Number of director chassis) + (Number of installed Application Blades x 3) RASlog message AN-1010 may be seen occasionally indicating “Severe latency bottleneck detected”. Even though it is a “Warning” message, it is likely to be a false alarm and can be ignored. POST diagnostics for the Brocade 5100 have been modified beginning with FOS v6.3.1b and v6.4.0 to eliminate an “INIT NOT DONE” error at the end of an ASIC diagnostic port loopback test. This modification addresses BL-1020 Initialization errors encountered during the POST portloopbacktest. (Defect 263200) It is important to note that the outputs of slotshow –p and chassisShow commands also display the maximum allowed power consumption per slot. These are absolute maximum values and should not be confused with the real-time power consumption on 16G blades. The Fabric OS v7.3.0 Release Notes v2.0 Page 49 of 114 chassisshow command has a “Power Usage (Watts):” field that shows the actual power consumed in real-time on 16G blades. Class 3 frames that have been trapped to CPU will be discarded in the following scenarios on DCX/DCX-4S/DCX 8510 during the following conditions: HA failover on DCX/DCX-4S/DCX 8510 platforms while running FOS v7.0 or later firmware Firmware upgrade from v7.0 to a later release on Brocade 300, 5100, VA-40FC, 5300, 6510 Firmware upgrade from v7.0.1 to a later release on Brocade 6505 Firmware upgrade from v7.1.0 to a later release on Brocade 6520 The QSFP information in the sfpshow output will indicate the ID field as all zeros. This is as designed. ras080:FID128:root> sfpshow 5/32 QSFP No: 8 Channel No:0 Identifier: 13 QSFP+ Connector: 12 MPO Parallel Optic Transceiver: 0000000000000000 16_Gbps id It is recommended that for directors with more than 300 E_Ports, the switch be disabled prior to executing the “switchCfgTrunk” command (used to disable or enable trunking on the switch). During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame drops on the E-port links. The Brocade Network Advisor seed switch should always have the highest FOS version used in the fabric. For login authentication through RADIUS, Brocade switch should be able to reach RADIUS servers through TCP authentication port (default 1812) and accounting port (default 1813). Both of these ports must be kept open in any firewall settings. When a firmware upgrade on a Brocade 6510 switch initiated through Brocade Network Advisor results with “failed to enforce new iptable rules” error message, the switch could be inaccessible via SSH and/or Telnet. Activating (from console) a new policy with rules of default active policy will restore access to the switch. Firmware downgrade from FOS v7.3.0 with one or more ports enabled with the Flow Generator feature as a SIM port will be blocked. The SIM ports configuration must first be disabled. Firmware upgrade to FOS v7.3.0 with one or more ports enabled with the Flow Generator feature as a SIM port will be blocked. The SIM ports configuration must first be disabled. FOS v7.3.0 includes a fix for defect 492340 where users may see frame drops on the back- end edge and core ports with FS8-18 and FX8-24 blades in DCX 8510 chassis. This fix will only take effect after the affected blades are powered off and on. After the fix takes effect, a new credit allocation model leads to fewer credits available for long distance ports. If there are long distance port configurations that have used up all the credits prior to applying this fix, some long distance ports may experience degraded performance. Open Defects in Fabric OS v7.3.0 Fabric OS v7.3.0 Release Notes v2.0 Page 50 of 114 Defects Open Defects in Fabric OS v7.3.0 This section lists defects with High or Medium Technical Severity open in Fabric OS v7.3.0 as of 12:00 PM on June 27, 2014. While these defects are still formally open they are unlikely to impede Brocade customers in their deployment of Fabric OS v7.3.0 and have been deferred to a later release. None of these defects have the requisite combination of probability and severity to cause significant concern to Brocade customers. Note that when a workaround to an issue is available, it is provided; otherwise, no recommended workaround is available at this time.

When the problem corrects itself , the customer's traffic may experience re-routes as the switch adjust routes to start using the previously missing paths. The correction of the problem to include the missing paths happens automatically within a time window of 30 minutes from when the problem Open Defects in Fabric OS v7.3.0 Fabric OS v7.3.0 Release Notes v2.0 Page 63 of 114 happened. Many of cases where this happens should be corrected much sooner. When a re-route occurs, out of order frames are always a possibility for mutli-hop routes. In this case, since the reroutes happen at a later time than a cust Condition: The switches must have Lossless DLS enabled. Then, the problem can happen when parallel paths to an existing domain are added due to a new domain joining the fabric. For example: a diamond topology where one of the points of diamond is offline and being brought back online. Workaround: The switches will automatically correct the problem within 30 minutes. If the customer wants to control when the reroute happens, they could bounce one of the missing ISLs and this will cause FSPF to correct the problem. (Note: if the ISL is a trunk, all members of the trunk must be bounced to generate the necessary events.) Adding a new ISL that does not join an existing trunk group will also generates the necessary events to fix the problem. Defect ID: DEFECT000513776 Technical Severity: High Probability: Medium Product: FOS Technology: Other Reported In Release: FOS7.3.0 Technology Area: Other Symptom: Name Server (NS) queue full condition leads to NS out of sync with local/remote devices and the device connectivity info will become inconsistent. Condition: When a new switch, which is in AllAccess mode and has local attached deviced, joins a large fabric consisting of a large number of devices (> 1000) and a large zone configuration (around 1MB) enabled, there is a possibility that the customer may see NS queue full condition. This happens due to Name Server discovery occurring before the existing fabric's zone configuration getting merged across to the new switch. Workaround: There are a couple workarounds for such a scenario and they are part of best-practices strategy for large fabrics. 1. When connecting a new switch to a fabric, put it in NoAccess mode. This will avoid the momentary transition to AllAccess and resultant RSCN storm to the fabric. 2. If connecting a new switch in AllAccess mode, take all devices connected to that switch offline to prevent RSCN storm. Recovery: Reboot the switch to recover from the error condition.
