To configure a 7210 and 7250 Queue Management policy

Purpose

A 7210 and 7250 Queue Management policy defines parameters for calculating drop precedence for ingress or egress queues. The policy defines values for CBS and MBS, and for high and low WRED slope calculations.

7210 and 7250 Queue Management policies are assigned to queues during queue configuration in the following policies:

The NFM-P assigns a default 7210 and 7250 Queue Management policy to a queue if no user-configured policy is explicitly assigned. The default policy cannot be deleted or modified. The default policy allocates the appropriate amount of CBS and MBS buffers based on whether the queue is associated with a SAP or a network port. The WRED slopes (high and low) are disabled in the default policy. If WRED is not configured in a 7210 and 7250 Queue Management policy, tail drop is used.

7210 and 7250 Queue Management policies are identified by the policy name and description; policy ID numbers are not used.

The 7210 and 7250 Queue Management policy is supported on the 7210 SAS-Mxp, 7210 SAS-R, and 7210 SAS-X.

If you are configuring a queue management policy for a 7250 IXR, see To configure a 7250 SROS Queue Management policy. For more information about QoS policy support on the 7250 IXR, see 7250 IXR QoS policies.

Support for specific parameters and features varies, depending on the chassis type. Local definitions of the policy do not necessarily support all configurations in the global policy.

Steps
 
1 

Choose Policies→QoS→SROS QoS→Slope→7210 and 7250 Queue Management from the NFM-P main menu. The 7210 and 7250 Queue Management Policies form opens.

2 

Click Create, or choose a policy and click Properties. The 7210 and 7250 Queue Management Policy (Create|Edit) form opens.

3
