OmniSwitch AOS Release 6 Network Configuration Guide

Configuration for policy rules and many global QoS parameters must specifically be applied to the config-
uration with the 

 command. Any parameters configured without this command are maintained 

for the current session but are not yet activated. For example, if you configure a new policy rule through 
the policy rule command, the switch cannot use it to classify traffic and enforce the policy action until the 
qos apply command is entered. For example:

-> policy rule my_rule condition c4 action a5

-> qos apply

The qos apply command must be included in an ASCII text configuration file when QoS commands are 
included. The command should be included after the last QoS command.

When the configuration is not yet applied, it is referred to as the pending configuration. 

Global Commands. Many global QoS commands are active immediately on the switch without qos 
apply. The settings configured by these commands will be active immediately. Other global commands 
must specifically be applied. The commands are listed in the following table: 

Port and Policy Commands. All port parameters and policy parameters must be applied with the qos 
apply command. 

The pending configuration is useful for reviewing policy rules before actually applying them to the switch. 
The show policy classify commands may be used to review information about new conditions before they 
are applied on the switch. See 

Applied policy rules may also be administratively disabled (inactive). If a rule is administratively disabled, 
the rule will exist in the applied configuration but will not be used to classify flows. For more information 
about disabling/re-enabling a policy rule, see
