Installing and Using Cisco’s VIRL

I thought it was way overdue for me to create a video of the LATEST VIRL install. It has been quite some time since my VIRL course at CBT Nugget, and Cisco has come a long way in simplifying things.

Enjoy!

The Modular Quality of Service CLI (MQC) Review – Policy Maps

Ant_Keith_QoS

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
