Configuration Examples
If the policy map is attached to Frame Relay DLCI 101 that is configured for Layer 2 VPN, the output
from the show policy-map interface command displays the following information:
Router# show policy-map serial4/0/0.1
Serial4/0/0.1: DLCI 101 -
Service-policy input: frde
Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
0 packets, 0 bytes
5 minute rate 0 bps
Police:

set-mpls-exp-imposition-transmit 1

Configuration Example of the set-cos-transmit Police Action
The following example shows how to configure the set-cos-transmit police action on the PRE2. In the
example, the traffic class group2 is policed at 20000 bps with a normal burst of 100 bytes. Traffic that
conforms to the rate is transmitted; traffic that exceeds the rate has the CoS bits set to 3; and traffic that
violates the rate has the CoS bits set to 4.

The following example shows sample output from the show running-config command for a 2-level
hierarchical policy that is configured with the set-cos-transmit action on the PRE2:
