To configure a 7250 Ingress CoS policy

Before you begin

A 7250 Ingress CoS policy associates ingress CoS values with forwarding classes and profiles, using selected classification policies. The 7250 Ingress CoS policy provides a container for various combinations of ingress classification policies.

Before you configure a 7250 Ingress CoS policy, configure the following polices as required:

The 7250 Ingress CoS policy is assigned to 7210,7250 and 1830 SAP Access Ingress policies; see To configure a 7210, 7250, and 1830 SAP Access Ingress policy.

You cannot assign a 7250 Ingress CoS policy to a 7210,7250 and 1830 SAP Access Ingress policy if the 7250 Ingress CoS policy contains a 7210/7250 MPLS LSP-EXP classification policy.

The NFM-P provides two default 7250 Ingress CoS policies, with policy IDs 1 and 2. The default policies are not configurable. Default policy 1 is assigned to 7210,7250 and 1830 SAP Access Ingress policies when no user-configured policy is explicitly assigned. Default policy 2 is assigned to 7250 Network Ingress policies when no user-configured policy is explicitly assigned.

If you are configuring an ingress classification policy for a 7250 IXR with SR OS, see To configure a 7250 SROS Ingress Classification policy. For more information about QoS policy support on the 7250 IXR, see 7250 IXR QoS policies.

Steps
 
1 

Choose Policies→QoS→SROS QoS→Ingress Classification→7250 Ingress CoS from the NFM-P main menu. The 7250 Ingress CoS form opens.

2 

Click Create, or choose an existing policy and click Properties. The Ingress CoS Classification Policy (Create|Edit) form opens.

3 

Configure the required parameters on the General tab.

4 

In the Classification policies panel, select the required classification policies:

  • Dot1p Classification

  • DSCP classification

  • LSP-EXP Classification

See Before you begin for information about classification policies.

If you are configuring a 7250 Ingress CoS policy for a 7210,7250 and 1830 SAP Access Ingress policy, do not select an LSP-EXP Classification policy.

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.
