Creating Policies Configuring QoS
page 24-24 OmniSwitch 6600 Family Network Configuration Guide April 2006
Creating Policy Conditions
This section describes how to create policy conditions in general. Creating policy conditions for particular
types of network situations is described later in this chapter.
Note. Policy condition configuration is not active until the qos apply command is entered. See “Applying
the Configuration” on page 24-46.
To create or modify a policy condition, use the policy condition command with the keyword for the type
of traffic you want to classify, for example, an IP address or group of IP addresses. In this example, a
condition (c3) is created for classifying traffic from source IP address 10.10.2.1:
-> policy condition c3 source ip 10.10.2.1
There are many options for configuring a condition, depending on how you want the switch to classify
traffic for this policy. An overview of the options is given here. Later sections of this chapter describe how
to use the options in particular network situations.
Note. The group options in this command refer to groups of addresses, services, or ports that you config-
ure separately through policy group commands. Rather than create a separate condition for each address,
service, or port, use groups and attach the group to a single condition. See “Using Condition Groups in
Policies” on page 24-34 for more information about setting up groups.
More than one condition parameter may be specified. Some condition parameters, like ToS and DSCP, are
mutually exclusive. Also, source and destination parameters cannot be combined in the same condition.
For supported combinations of condition parameters, see “Condition Combinations” on page 24-6.
The condition will not be active on the switch until you enter the qos apply command.
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.
