Configuring priority control rewrite

This section describes how to configure priority control rewrite which rewrites priority control
information of packets specified with combination of MAC address, packet format, Ethernet
type, VLAN ID and CoS value.
13.2.1

IP Precedence value rewrite

This section describes how to configure IP precedence value rewrite which rewrites IP
precedence value of packets which has the specified CoS value in the specified port in VLAN.
Beginning in privileged EXEC mode, follow these steps to configure IP precedence value
rewrite on specific interface:
Command
Step 1 configure
Step 2 diffserv
Step 3 class-map match-all
class-map-name
Step 4 match cos <0-7>
Step 5 exit
Step 6 policy-map policy-name in
Step 7 class class-map-name
Step 8 mark ip-precedence <0-7>
Step 9 exit
Step 10 exit
Step 11 interface interface-id
Step 12 service-policy in policy-map-name
Step 13 exit
Step 14 exit
Step 15 show class-map
Step 16 show policy-map
Step 17 show policy-map interface
interface-id in
To configure an IP precedence rewrite to interface, use the DiffServ configuration
command. To display the policy configuration, use show policy-map privileged EXEC
command. To display the class configuration, use show class-map privileged EXEC
command.

Purpose
Enter global configuration mode
Enable DiffServ Admin mode.
Create a DiffServ class with a class-map
name.
Configure a match condition based on a
CoS value..
Return to global configuration mode.
Create a DiffServ policy with a policy-map
name.
Attach the DiffServ class to this policy.
Configure marking action on the specific IP
precedence value.
Return to policy-map configuration mode.
Return to global configuration mode.
Specify the interface, and enter interface
configuration mode. The interface can be a
physical Layer 2 interface or a port channel
(logical interface).
Specify the policy which will be applied to
this interface.
Return to global configuration mode.
Return to privileged EXEC mode.
Verify the configuration.
