Defining Policy; Applying Policy - 3Com MSR 50 Series Configuration Manual

Defining Policy

The corresponding relationship between the classes and traffic behaviors in this
policy are defined. Each traffic behavior includes a group of QoS actions.
Follow these steps to specify the traffic behavior for the class in the policy
To do...
Enter system view
Define the policy and enter the
policy view
Specify the traffic behavior for
the class in the policy
Display configuration

If an ACL is defined in a traffic classification rule in a QoS policy, the processing
methods vary with different interfaces

Applying Policy

Configuration procedure
The qos apply policy command maps a policy to a specific interface. One policy
mapping can be applied on multiple interfaces. Only one policy can be applied on
one direction (inbound or outbound) of an interface.
Follow these steps to apply a policy to the interface
To do...
Enter system view
Enter interface
view or port
group view
Apply a policy on the
interface
Apply a policy on the layer 2
interface module
For forwarding by software, if the if-match references the deny action in ACL
rule, exit this if-match and continue to search for the subsequent rules;
For ASIC forwarding, neglect actions in ACL rule, and reference the action
defined in traffic behavior. Only the classification domain in ACL is used for
packet matching.

Use either command
Configured in interface view, the
setting is effective only on the
current interface; configured in
port group view, the setting is
effective on all the ports in the
current port group.
