Creating Policies

Removing Condition Parameters

To remove a classification parameter from the condition, use no with the relevant keyword. For example:
-> policy condition c3 no source ip
The specified parameter (in this case, a source IP address) will be removed from the condition (c3) at the
next qos apply.
Note. You cannot remove all parameters from a policy condition. A condition must be configured with at
least one parameter.

Deleting Policy Conditions

To remove a policy condition, use the no form of the command. For example:
-> no policy condition c3
The condition (c3) cannot be deleted if it is currently being used by a policy rule. If a rule is using the
condition, the switch will display an error message. For example:
ERROR: c3 is being used by rule 'my_rule'
In this case, the condition will not be deleted. The condition (c3) must first be removed from the policy
rule (my_rule). See
If c3 is not used by a policy rule, it will be deleted after the next qos apply.

Creating Policy Actions

This section describes how to configure policy actions in general. Creating policy actions for particular
types of network situations is described later in this chapter.
To create or modify a policy action, use the policy action command with the desired action parameter. A
policy action should specify the way traffic should be treated. For example, it might specify a priority for
the flow, a source address to rewrite in the IP header, or it may specify that the flow may simply be
dropped. For example:
-> policy action Block disposition drop
In this example, the action (Block) has a disposition of drop (disposition determines whether a flow is
allowed or dropped on the switch). This action may be used in a policy rule to deny a particular type of
traffic specified by a policy condition.
Note. Policy action configuration is not active until the qos apply command is entered. See
Configuration" on page
More than one action parameter may be specified. Some parameters may be mutually exclusive. In addi-
tion, some action parameters are only supported with particular condition parameters. For information
about supported combinations of condition and action parameters, see
page 40-6 and "Action Combinations" on page
about command syntax.
