3Com Router Command Reference Guide Addendum for V1.2

View

Interface view

Parameter

inbound: Inbound direction.

outbound: Outbound direction.

policy-name: Policy name.

Description

Using the qos apply policy command, you can attach an associated QoS policy to an interface. Using the undo qos apply policy command, you can delete associated QoS policy from an interface.

If the sum of the bandwidths specified for the assured and expedited forwarding classes in a QoS policy exceeds the available bandwidth on the interface, the policy cannot be applied on the interface. When the available bandwidth on the interface is modified, the policy will be deleted if the sum of the bandwidths specified for the assured and expedited forwarding classes exceeds the available bandwidth on the interface. af, ef, wfq and gts cannot be configured for inbound policies.

The application rule of QoS policy in interface view is as follows.

On a common physical interface or the VT invoked by MP, you can apply the policy configured with various features, including remark, car, gts, af, ef, wfq and wred.

The policy configured with gts, ef, af and wfq cannot be configured on an inbound interface as an inbound policy.

Sub-interface does not support queue (ef, af and wfq) feature but support TS (gts) and TP (car). Therefore, the policy configured with TS and TP only can be applied to a sub-interface.

Example

Apply the policy 3COM in the outbound direction of Ethernet0.

[3Com-Ethernet0]qos apply policy outbound 3COM
