Enabling Layer 2 Control Packet Qos - Cisco Catalyst 4500 Series Configuration Manual

Configuring Layer 2 Control Packet QoS

Enabling Layer 2 Control Packet QoS

To enable Layer 2 control packet QoS, perform this task:
Command
Step 1
Switch# config terminal
Step 2
Switch(config)# [no] qos control-packets
[bpdu-range | cdp-vtp | eapol | sstp |
protocol-tunnel | lldp]
Step 3
Switch(config)# end
Step 4
Switch# show run | inc qos control-packets

The following example shows how to enable QoS for CDP packets and to apply a policer to CDP packets
arriving on interface gi3/1 and VLAN 1:
Switch# config terminal
Switch(config)# qos control-packets cdp-vtp
Switch(config)# end
Switch# show run | inc qos control-packets
qos control-packets cdp-vtp
Switch# show class-map
Class Map match-any system-control-packet-cdp-vtp (id 1)
Create a policy map and attach it to interface gi3/1 , vlan 1
Switch# config terminal
Switch(config)# policy-map police_cdp
Switch(config-pmap)# class system-control-packet-cdp-vtp
Switch(config-pmap-c)# police 32k
Switch(config-pmap-c)# end
Switch(config)# interface gi3/1
Switch(config-if)# vlan 1
Switch(config-if-vlan-range)# service-policy in police_cdp
