Example 3-3: Configuring WRR for egress queues

This example is used for configuring WRR on egress queues according to the ingress port of the

traffic.

Ingress ports 1-3 (these ports MAY be carrying a mixture of packets

from different VLAN packets either with or without VLAN tags)

class-map cmap1

policy-map pmap1

class cmap1

set queue 6

policy-map pmap2

class cmap1

set queue 5

policy-map pmap3

class cmap1

set queue 4

interface port1.0.1

service-policy input pmap1

interface port1.0.2

service-policy input pmap2

interface port1.0.3

service-policy input pmap3

interface port1.0.24

wrr-queue group 1 weight 6 queues 4

wrr-queue group 1 weight 12 queues 5

wrr-queue group 1 weight 24 queues 6

This set of commands will set the egress queue of any traffic received from port 1 to egress queue

6, from port 2 to egress queue 5 and from port 3 to egress queue 4. And on egress, the WRR

algorithm will do the following: for every 4 packets from queue 6, 2 packets will leave queue 5 and 1

packet will leave queue 4.
