Configuring QoS on the Switch
For PFC2 or PFC3A, this example shows how to create an aggregate excess rate policer with a 64-Kbps
rate limit and a 128-Kb burst limit that drops the traffic exceeding these values:
Console> (enable) set qos policer aggregate test rate 64 burst 128 drop
QoS policer for aggregate test created successfully.
Console> (enable) show qos policer config aggregate test
QoS aggregate policers:
QoS aggregate policers:
Aggregate name Normal rate (kbps) Burst size (kb) Normal action
----------------------------- ------------------ --------------- -------------
test 64 128 policed-dscp
Excess rate (kbps) Burst size (kb) Excess action
------------------ --------------- -------------
64 128 drop
ACL attached
------------------------------------
Console> (enable)
For PFC2 or PFC3A, this example shows how to create an aggregate excess rate policer with a 64-Kbps
rate limit and a 100-Kb burst limit that will cause all out-of-profile packets to be marked down as
specified in the normal markdown DSCP map:
Console> (enable) set qos policer aggregate test2 rate 64 burst 100 policed-dscp
QoS policer for aggregate test2 created successfully.
Console> (enable) show qos policer config aggregate test2
QoS aggregate policers:
Aggregate name Normal rate (kbps) Burst size (kb) Normal action
----------------------------- ------------------ --------------- -------------

For PFC2 or PFC3A, this example shows how to create an aggregate excess rate policer with a 64-Kbps
rate limit and a 128-Kb burst limit that will cause the traffic that exceeds the normal rate of 64 Kbps and
a burst size of 96 Kb to be marked down as specified in the normal markdown DSCP map, and the traffic
that exceeds 128 Kbps and a burst size of 96 Kb to be dropped:
Console> (enable) set qos policer aggregate test3 rate 64 policed-dscp erate 128 drop
burst 96
QoS policer for aggregate test3 created successfully.
Console> (enable) show qos policer config aggregate test3
