In the following example, the DSCP value of ingress traffic is trusted:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.1
awplus(config-if)# auto-qos-med trust dscp
See Table 231 for a list of commands that are contained in this macro.
awplus (config)# mls qos map cos-
queue 5 to 7 Maps CoS priority 5 to egress queue 7.
awplus (config-if)# wrr-queue weight
3,3,1,1,12,0,0,0 Assigns a weight to the eight default CoS
queues where weight specifies the number of
packets a port transmits from a queue before
going to the next queue. By default, the CoS
queues start with queue 0. CoS queues 0 and 1
are assigned a weight of 3. CoS queues 2 and 3
are assigned a weight of 1. CoS queue 4 is
assigned a weight of 12. CoS queues 5 through
7 are assigned a weight of 0.
awplus (config-if)# service-policy
input AutoQoS Associates policy map “AutoQoS” with the given
port which, in this example, is port 1.
