Configuring PFC QoS
Enabling Queueing-Only Mode
To enable queueing-only mode on the router, perform this task:
When you enable queueing-only mode, the router does the following:
• Disables marking and policing globally
• Configures all ports to trust Layer 2 CoS
Note The router applies the port CoS value to untagged ingress traffic and to traffic that is received
through ports that cannot be configured to trust CoS.
This example shows how to enable queueing-only mode:
Router# configure terminal
Router(config)# mls qos queueing-only
Router(config)# end
Router#
Enabling Microflow Policing of Bridged Traffic
Note With a PFC2, to apply microflow policing to multicast traffic, you must enter the mls qos bridged
command on the Layer 3 multicast ingress interfaces.
By default, microflow policers affect only routed traffic. To enable microflow policing of bridged traffic
on specified VLANs, perform this task:
Command Purpose
Step 1
Router(config)# mls qos queueing-only
Enables queueing-only mode on the router.
Router(config)# no mls qos queueing-only
Disables PFC QoS globally on the router.
Note You cannot disable queueing-only mode
separately.
Step 2
Router(config)# end
Exits configuration mode.
Step 3
Router# show mls qos
Verifies the configuration.
Command Purpose
Step 1
Router(config)# interface {{vlan
vlan_ID
} |
{
type
1
slot/port
}}
1.
type
= ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Selects the interface to configure.
Step 2
Router(config-if)# mls qos bridged
Enables microflow policing of bridged traffic, including
bridge groups, on the VLAN.
Router(config-if)# no mls qos bridged
Disables microflow policing of bridged traffic.
Step 3
Router(config-if)# end
Exits configuration mode.
Step 4
Router# show mls qos
Verifies the configuration.
