Enabling Microflow Policing Of Bridged Traffic; Enabling Vlan-Based Pfc Qos On Layer 2 Lan Ports - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Configuring PFC QoS

Enabling Microflow Policing of Bridged Traffic

By default, microflow policers affect only routed traffic. To enable microflow policing of bridged traffic
on specified VLANs, perform this task:
Command
Step 1
Router(config)# interface {{vlan vlan_ID} |
1
{type slot/port}}
Step 2
Router(config-if)# mls qos bridged
Router(config-if)# no mls qos bridged
Step 3
Router(config-if)# end
Step 4
Router# show mls qos
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to enable microflow policing of bridged traffic on VLANs 3 through 5:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface range vlan 3 - 5
Router(config-if)# mls qos bridged
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show mls qos | begin Bridged QoS
Bridged QoS is enabled on the following interfaces:

Enabling VLAN-Based PFC QoS on Layer 2 LAN Ports

You can attach policy maps to Layer 3 interfaces for application of PFC QoS to egress traffic.
Note
VLAN-based or port-based PFC QoS on Layer 2 ports is not relevant to application of PFC QoS to
egress traffic on Layer 3 interfaces.
By default, PFC QoS uses policy maps attached to LAN ports. For ports configured as Layer 2 LAN
ports with the switchport keyword, you can configure PFC QoS to use policy maps attached to a VLAN.
Ports not configured with the switchport keyword are not associated with a VLAN.
To enable VLAN-based PFC QoS on a Layer 2 LAN port, perform this task:
Command
Step 1
Router(config)# interface {{type
{port-channel number}}
