Policy-Map Commands
XSR CLI Reference Guide 12-99
Syntax of the “no” Form
The no form of this command removes a previously set IP DSCP:
no set ip dscp
Mode
Policy‐Map Class configuration: XSR(config-pmap-c-xx)#
Example
In the following example, the IP DSCP TOS byte is set to 8 for class1 and cs2 for class2 in policy57:
XSR(config)#policy-map policy57
XSR(config-pmap)#class class1
XSR(config-pmap-c)#set ip dscp 8
XSR(config-pmap)#class class2
XSR(config-pmap-c)#set ip dscp cs2
set ip precedence
This command sets the precedence value in the IP header. The network gives priority (or some
type of expedited handling) to marked traffic through the application of CBWFQ or RED at points
downstream in the network. Typically, you set IP Precedence at the edge of the network (or
administrative domain); data then is queued based on the precedence. CBWFQ can speed up
handling for certain precedence traffic at congestion points.
Syntax
set ip precedence ip-precedence-value
Syntax of the “no” Form
