In the first part of the MQC review – we examined class maps. These devices place our traffic into containers that we can assign QoS actions to. In this article, we are going to look at policy maps for assigning those actions.

Here I will create a quick class map, verify the class map, and then enter policy map configuration mode:

R1(config)#class-map match-any CM_ICMP

R1(config-cmap)#match access-group 100

R1(config-cmap)#exit

R1(config)#exit

R1#! The access-list 100 is not shown in this configuration

R1#show class-map

 Class Map match-any class-default (id 0)

   Match any 

 Class Map match-any CM_ICMP (id 1)

   Match access-group  100 

R1#conf t

R1(config)#policy-map PM_ICMP

R1(config-pmap)#?

Policy-map configuration commands:

  class        policy criteria

  description  Policy-Map description

  exit         Exit from policy-map configuration mode

  no           Negate or set default values of a command

  rename       Rename this policy-map

R1(config-pmap)#

As you can see from the above configuration, there is not much going on in policy map configuration mode. We can add a description or rename the policy map but that is about it. The magic happens when we enter policy map class configuration for one of the classes that we configured: Continue reading The Modular Quality of Service CLI (MQC) Review – Policy Maps →
