How to Configure QoS Congestion Management on Cisco ASR 9000 Series Routers
Purpose
Specifies the bandwidth allocated for a class belonging to a
policy map.
• In this example, class class2 is guaranteed 10 percent of
the interface bandwidth.
Specifies how to allocate leftover bandwidth to various
classes.
The remaining bandwidth of 40 percent is shared by
•
class class1 (see Steps 4 and 5) and class2 in a 20:80
ratio: class class1 receives 20 percent of the 40 percent,
and class class2 receives 80 percent of the 40 percent.
Returns the router to policy map configuration mode.
Returns the router to global configuration mode.
Enters interface configuration mode and configures an
interface.
Attaches a policy map to an input or output interface to be
used as the service policy for that interface.
• In this example, the traffic policy evaluates all traffic
leaving that interface.
