3Com MSR 50, MSR 30 manual Qos apply policy layer 2 interface view or port group view, 1805

1805

Parameters inbound: Inbound direction.

outbound: Outbound direction.

policy-name: Policy name, a string of characters in the range 1 to 31.

dynamic: If this argument is applied when CBQ is applied on an interface, the CBQ bandwidth will be dynamically changed with the change of the interface bandwidth.

Description Use the qos apply policy command to apply associated policy to the interface.

Use the undo qos apply policy command to delete the associated policy from the interface.

To successfully apply the policy to the interface, you must make sure that the sum of bandwidth specified for the AF and EF classes in the policy is smaller than the available bandwidth of the interface. You can modify the available bandwidth of the current interface. If the sum of their bandwidth still exceeds that modified value, the policy will be deleted.

For a policy to be applied in the inbound direction, it cannot contain classes associated with traffic behaviors specified using queue af, queue ef, queue wfq, or gts.

Applying the policy on interface following these rules:

■The VT interface referenced by common physical port and MP can apply the policy configured with various features, including remark, car, gts, queue af, queue ef, queue wfq, wred, etc.

■The policy configured with TS (e.g. gts) and queue (e.g. queue ef, queue af, queue wfq) features cannot be applied on the inbound interface as the input direction policy.

■Only the outbound direction policy configured with queue (e.g. queue ef, queue af, queue wfq) features can be applied on ATM PVC.

■The subinterface does not support queue (e.g. queue ef, queue af, queue wfq) features but support TS (e.g. gts) and TP (e.g. car). Therefore, the policy configured with TS and TP can be applied on the sub-interface.

Examples # Apply the policy USER1 in the outbound direction of interface Ethernet1/0.
