OmniSwitch AOS Release 6 Network Configuration Guide

To remove addresses from a network group, use no and the relevant address(es). For example:

-> policy network group netgroup3 no 173.21.4.39

This command deletes the 173.21.4.39 address from netgroup3 after the next qos apply.

To remove a network group from the configuration, use the no form of the policy network group 
command with the relevant network group name. The network group must not be associated with any 
policy condition or action. For example:

-> no policy network group netgroup3

If the network group is not currently associated with any condition or action, the network group 
netgroup3 is deleted from the configuration after the next qos apply.

If a condition or an action is using netgroup3, the switch will display an error message similar to the 
following:

ERROR: netgroup3 is being used by condition 'c4'

In this case, remove the network group from the condition first, then enter the no form of the policy 
network group command. For example:

-> policy condition c4 no source network group

-> no policy network group netgroup3

The policy condition command removes the network group from the condition. (See 

 for more information about configuring policy conditions.) The network group 

will be deleted at the next qos apply.

Policy services are made up of TCP or UDP ports or port ranges. They include source or destination ports, 
or both, but the ports must be the same type (TCP or UDP). Mixed port types cannot be included in the 
same service. 

Policy services may be associated with policy service groups, which are then associated with policy condi-
tions; or they may be directly associated with policy conditions.

To create a service, use the 

 command. With this command, there are two different methods 

for configuring a service. You can specify the protocol and the IP port; or you can use shortcut keywords. 
The following table lists the keyword combinations: 

An IP protocol (TCP or UDP), source IP port and/or destination IP port (or port range) must be associated 
with a service. IP port numbers are well-known port numbers defined by the IANA. For example, port 
numbers for FTP are 20 and 21; Telnet is 23.

Basic procedure for either TCP or 
UDP service

The protocol must be specified with 
at least one source or destination 
port.
