Configuring QoS Creating Policies

OmniSwitch 6800/6850/9000 Network Configuration Guide June 2006 page 26-27

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 26-47.

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 26-35 for more information about setting up groups.

More than one condition parameter may be specified. Some condition parameters, such as are mutually

exclusive. For supported combinations of condition parameters, see “Condition Combinations” on

page 26-6.

The condition will not be active on the switch until you enter the qos apply command.
