2.Policy map does not give option of priority instead policy map actions on Catalyst 3550 can include trusting the CoS, DSCP, or IP precedence values in the traffic class; setting a specific CoS, DSCP, or IP precedence value in the traffic class; and specifying the traffic bandwidth limitations for each matched traffic class (policer) and the action to take (marking) when the traffic is out of profile.
3.WRR is a mechanism that is used in output scheduling on the 3550. WRR works between three or four queues (if there is no strict priority queue). The queues that are used in the WRR are emptied in a round-robin fashion, and you can configure the weight for each queue.
4.Gigabit capable ports has egress expedite queue facility using "priority-queue out" command instead of "priority"
So on typical router WRR or SRR is not available
Catalyst 3550 supports WRR
Catalyst 3760 supports SRR
Catalyst 3750 supports SRR
Catalyst 6500 supprts WRR & SRR
For more information WRR on Catalyst 3550 refer below link
Thanks for the reply. We have Cat 6500 switches. We have a tengigabit link joining two locations. The port is capable of 1p7q8t. In our review, we were adviced to use CBWFQ for QoS. The document on CISCO website on CBWFQ did not have the 6500 in the supported platform.
Are you saying that CBWFQ is for routers and not switches? For the 6500, what would you recommend and do you have any examples?
