Cisco Catalyst 9500

The following commands can be used to monitor application visibility on the switch and access ports.
Table 8: Monitoring Application Visibility Commands on the Switch
PurposeCommand
Displays the statistics gathered by the NBAR Protocol
Discovery feature.
• (Optional) Enter keywords and arguments to fine-tune
the statistics displayed. For more information on each
of the keywords, refer to the show ip nbar
protocol-discoverycommand in Cisco IOS Quality
of Service Solutions Command Reference.
show ip nbar protocol-discovery [interface
interface-type interface-number]
[stats{byte-count | bit-rate | packet-count
| max-bit-rate}] [protocol protocol-name
| top-n number]
Displays information about policy map applied to the
interface.
show policy-map interface interface-type
interface-number
Displays statistics about all flows on the specified switch.show platform software fed switch switch id

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
Device(config-pmap-c)# police 200000
Device(config-pmap-c)# set dscp 10
Device(config-pmap-c)#end
This example shows how to apply policy maps to a switch port:
Device# configure terminal
Device(config)# interface GigabitEthernet 1/0/1
Device(config-if)# switchport mode access
Device(config-if)# switchport access vlan 20
Device(config-if)# service-policy input POLICING_IN
Device(config-if)#end
This example shows how to create class maps based on NBAR attributes.
