HOME BLOG TUTORIALS ABOUT CONTACT Tutorial: What is the difference between bandwidth percent and bandwidth remaining percent? by Arden Packeer | on March 15th, 2008 | 30 comments QOS & VOIP One of the most common questions that CCIE candidates face when studying QOS MQC for the lab is “What is the difference between bandwidth percent and bandwidth remaining percent?”. Both are used in CBWFQ when implementing congestion management but what is the difference? The answer to this question is the focus of this tutorial. We will be using the following topology for this tutorial: About the Author Arden Packeer is a Cisco Certified Internetwork Expert (CCIE #20716) working in the Advanced Services team at Cisco Systems (Melbourne, Australia).[Read More] Dynagen .net Configuration File: !"#$%&#$'(')*+, $-.*$,/,/'(')*+, /#0,1'('2345 ' 61#7.1"#$%8 ' ''''66234588 ''''''''&/.!,'('9:*#!*./';&1,$9<=>./&-$9&/.!,$972345?&@A#2$?/BCDE4?FCG&> ''''''''H'I>'J&>+K'L'M>&K'+$,'N#*O.*0'$1.$",$P ''''''''H'&/.!,'('L#-%LFE55?&/.!,$L7FE55?Q@A#2$?/BCDE4?F.C&/.!, ''''''''*./'('A3 ' ''''66RIM)SR'RD88 ''''''''N5L5'('JTU'D ''''''''NDL5'('JTU'E ''''''''7#>$#1,'('E555 ''''''''/#0,1'('2345 ' ''''66RIM)SR'RE88 ''''''''N5L5'('JTU'2 ''''''''NDL5'('JTU'E ''''''''7#>$#1,'('E55D ''''''''/#0,1'('2345 Subscribe to Newsletter!

The Scenario: “The users on the 1.1.1.0/24 subnet have been complaining of slow network response times recently when connecting to services on the 2.2.2.0/24. Users on the 1.1.1.0/24 subnet use voice and web applications. During times of congestion we want the web applications to be guaranteed bandwidth. Also, delay sensitive Voice traffic needs to be given priority over all other traffic.” The scenario above is typical of something you might see in your environment. We have congestion happening on an interface on the ethernet link between R1 and R2. We need to implement a congestion management strategy during times of congestion so that voice and web traffic are given traffic guarantees. Lets say that we want to reserve at least 20% of the bandwidth during times of congestion for web traffic. Lets implement that first and we’ll get back to voice traffic later. First lets just do a quick check of bandwidth of R1: RDV7#>N&!WH&>%'NDL5 RDV7#>N&!?&NWHN.&*?X+,+, RDH$"'X+,+,&>!'&>%'NDL5 Y>%,*N.7,';.$%S%",*>,%DL5'X+,+,&>!'$%*.%,!=P'N.&* ''Y>-+%'X+,+,P'5LFZL5L5'V$&B,L/.KL0*#-$LN1+$",$W[')#%.1'#+%-+%'0*#-$P'5 ''\+,+,&>!'$%*.%,!=P'O,&!"%,0'N.&* ''I+%-+%'X+,+,P'5LD555L34L5'V$&B,L/.K'%#%.1L%"*,$"#10L0*#-$W ''''']#>^,*$.%&#>$''5LDLEZ3'V.7%&^,L/.K'.7%&^,L/.K'%#%.1W '''''R,$,*^,0']#>^,*$.%&#>$'5L5'V.11#7.%,0L/.K'.11#7.%,0W '''''T^.&1.G1,'_.>0O&0%"'FZ555'@&1#G&%$L$,7 You can see above the available bandwidth when you implement a fair-queueing on an interface is 75,000 kbs. Wait a second, this is a fast ethernet interface! Shouldn’t the available bandwidth be 100,000 kbs (100 Mbs). Why are we operating at only 75%? What happened to the other 25%?

Summary: By default. no congestion means that the priority traffic can go above the configured rate but will not be prioritised over other traffic (ie traffic above the configured rate is not gauranteed llq). then what happens if you also specify "30 percent remaining bandwidth" to Bulk Data flows?

Now back to labs.22 / 03 / 2008 Reply Good article. and then you specify "60 percent remaining bandwidth" to Critical Data flows.This may well be what you meant to say. Australia). The bandwidth percent and priority percent commands makes reservations from the total reservable interface bandwidth The bandwidth remaining percent command makes reservations from the available bandwidth (whats left over of the total reservable bandwidth after the other reservations are made). 25% of the total reservable interface bandwidth is reserved for routing protocols and important layer 2 traffic...I've bookmarked this for when I reach QoS :-)Richard Andy Saturday .
