Examples: Application Visibility and Control Configuration
This example shows how to create class maps with apply match protocol filters for application name:
Device# configure terminal
Device(config)# class-map match-any NBAR-VOICE
Device(config-cmap)# match protocol ms-lync-audio
Device(config-cmap)#end
This example shows how to create policy maps and define existing class maps for egress QoS:
Device # configure terminal
Device(config)# policy-map test-avc-up
Device(config-pmap)# class cat-browsing
Device(config-pmap-c)# police 150000
Device(config-pmap-c)# set dscp 12
Device(config-pmap-c)#end
This example shows how to create policy maps and define existing class maps for ingress QoS:
Device# configure terminal
Device(config)# policy-map test-avc-down
Device(config-pmap)# class cat-browsing
