How to Configure QoS Congestion Management on Cisco ASR 9000 Series Routers
Purpose
Enters global configuration mode.
Enters policy map configuration mode.
Creates or modifies a policy map that can be attached to
•
one or more interfaces to specify a service policy.
Enters policy map class configuration mode.
• Specifies the name of the class whose policy you want
to create or change.
Configures traffic policing and enters policy map police
configuration mode.
In this example, the low-latency queue is restricted to
•
250 kbps to protect low-priority traffic from starvation
and to release bandwidth.
