Creating Policy Conditions; Removing Condition Parameters - Alcatel OmniSwitch 6800 Series Network Configuration Manual

Configuring QoS

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
the Configuration" on page
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
Policies" on page 21-34
More than one condition parameter may be specified. Some condition parameters, such as are mutually
exclusive. For supported combinations of condition parameters, see
page 21-6.

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.
