Configuring QoS

Creating Policies

OmniSwitch AOS Release 6 Network Configuration Guide

page 40-35

Note. If you combine priority with 802.1p, dscp, tos, or map, in an action, the priority value is used to 
prioritize the flow.

To remove an action parameter or return the parameter to its default, use no with the relevant keyword.

-> policy action a6 no priority

This example removes the configured priority value from action a6. If any policy rule is using action a6, 
the default action will be to allow the flow classified by the policy condition.

The specified parameter (in this case, priority) will be removed from the action at the next qos apply.

To remove a policy action, use the no form of the command.

-> no policy action a6

The action cannot be deleted if it is currently being used by a policy rule. If a rule is using the action, the 
switch will display an error message. For example:

ERROR: a6 is being used by rule ‘my_rule’

In this case, the action will not be deleted. The action (a6) must first be removed from the policy rule 
(my_rule). See 

 for more information about setting up rules. 

If a6 is not used by a policy rule, it will be deleted after the next qos apply.

This section describes in general how to create or delete policy rules and rule parameters. See later 
sections of this chapter for more information about creating particular types of policy rules.

To create a policy rule, use the policy rule command and specify the name of the rule, the desired condi-
tion, and the desired action. 

In this example, condition c3 is created for traffic coming from IP address 10.10.8.9, and action a7 is 
created to prioritize the flow. Policy rule rule5 combines the condition and the action, so that traffic arriv-
ing on the switch from 10.10.8.9 will be placed into the highest priority queue.
