To configure a 7250 SROS Remarking policy

Before you begin

A 7250 SROS Remarking policy maps forwarding classes and profile states to Dot1p, DSCP, DE, and LSP-EXP values for egress traffic.

The 7250 SROS Remarking policy is assigned to L2 access interfaces on VPLS and VLL services, to L3 access interfaces on IES and VPRN services, and to network interfaces. See the following procedures:

for VLL: To assign ingress and egress QoS policies to a VLL L2 access interface
for VPLS: To assign QoS policies or to enable a MAC override address to a VPLS or MVPLS L2 access interface
for IES: To assign ingress and egress QoS policies to an IES L3 access interface
for VPRN: To assign ingress and egress QoS policies to a VPRN L3 access interface
for L3 network interfaces: To create an L3 network interface on a routing instanceand To configure L3 network interfaces

7250 SROS Remarking policies are identified by the policy name; policy ID numbers are not used.

The NFM-P provides three default 7250 SROS Remarking policies:

access default, for L2 and L3 access interfaces
network default, for network interfaces
push-implicit-null-default, for PHP network interfaces

Note: The push-implicit-null-default policy is supported only for releases earlier than 22.2 R1 on the IXR nodes.

The default policies are not configurable. A default policy is assigned if no user-configured 7250 SROS Remarking policy is explicitly assigned.

For more information about QoS policy support on the 7250 IXR, see 7250 IXR QoS policies.

Steps


1	Choose Policies→QoS→SROS QoS→Egress Remarking→7250 SROS Remarking from the NFM-P main menu. The 7250 SROS Remarking form opens.
2	Click Create, or choose an existing policy and click Properties. The 7250 SROS Egress Remark Policy (Create\|Edit) form opens.
3	Configure the required parameters on the General tab. If you are configuring a policy for a 7250 IXR NE that supports SROS FC mapping policies for egress remarking, assign the FC mapping policies in the Properties panel, then go to Step 5. For more information about SROS FC mapping policies, see To configure FC mapping policies for egress remarking on the 7250 IXR.
4	Click on the Forwarding Classes tab to configure remarking values for FCs. Choose a forwarding class and click Properties. The Egress Remark Forwarding Class form opens. Configure the required parameters. Save your changes and close the form.
5	Click OK to save the policy and close the form, or click Apply to save the policy. See To release and distribute a policy to distribute the policy to NEs. End of steps
