Policing Configuration
This chapter contains a complete sample of configuration of Policing for Pipe and Uniform models.This example shows configurations using LDP.
Configuration
Configuring Remarking for MPLS EXP bits require following configurations:
• Enabling label-switching on the interface on NSM.
• Configuring LSP (Using LDP, Static or RSVP-TE, in this example we are using LDP for setting UP LSP).
• Running an IGP (Internal Gateway Protocol), for example, OSPF, to distribute reachability information within the MPLS cloud.
• Enable QoS, Configuring Policing on interface Level.
Topology
Basic Policing Topology
R1
The following steps describes how to configure Policing.
Note: Basic configuration for Policing is same as that of the configurations given in Remarking chapter
 
(config)#class-map cmap1
Enter Class-map mode
(config-cmap-qos)#match dscp 2
Configure match criteria as DSCP with Value 2
(config-cmap-qos)#exit
Exit Class-map mode
(config)#policy-map pmap1
Enter policy-map mode
(config-pmap-qos)#class cmap1
Assign Class cmap1 to Policy-map pmap1
(config-pmap-c-qos)#police cir 1 mbps conform set-mpls-class 6 violate drop
Police DSCP 2 packets @ Committed information rate 1 mbps, and map DSCP 2 to class 6.
(config-pmap-c-qos)#exit
Exit out of policy-class-map mode
(config-pmap-qos)#exit
Exit out of Policy-map mode
(config)#interface eth2
Enter eth0 interface
(config-if)#service-policy type qos input pmap1
Assign service-policy to interface on in-direction
(config-if)#exit
Exit interface mode.
