How to Configure QoS Congestion Management on Cisco ASR 9000 Series Routers
Purpose
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. The traffic policing feature works with
a token bucket algorithm.
Configures the action to take on packets that conform to the
rate limit. The action argument is specified by one of the
following keywords:
drop—Drops the packet.
•
set—Has the following keywords and arguments:
•
cos value—Sets the class of service value. Range is
–
0 to 7.
discard-class value—Sets the discard class on IP
–
Version 4 (IPv4) or Multiprotocol Label Switching
(MPLS) packets. Range is 0 to 7.
– dscp [tunnel] value—Sets the differentiated
services code point (DSCP) value and sends the
packet.
mpls experimental {topmost | imposition}
–
value—Sets the experimental (EXP) value of the
Multiprotocol Label Switching (MPLS) packet
topmost label or imposed label. Range is 0 to 7.
precedence precedence—Sets the IP precedence
–
and sends the packet.
transmit—Transmits the packets.
•
Configures the action to take on packets that exceed the rate
limit. The action argument is specified by one of the
keywords specified in
Returns the router to policy map class configuration mode.
