Command Entry Rules and Syntax

Using the CLI

page 6-4

OmniSwitch AOS Release 6 Switch Management Guide

The CLI contains show commands that allow you to view configuration and switch status on your console 
screen. The show syntax is used with other command keywords to display information pertaining to those 
keywords.

For example, the show vlan command displays a table of all VLANs currently configured, along with 
pertinent information about each VLAN. Different forms of the show vlan command can be used to 
display different subsets of VLAN information. For example the show vlan rules command displays all 
rules defined for a VLAN.

The OmniSwitch CLI Reference Guide defines all CLI commands and explains their syntax. Whenever a 
command

 

has a “no” form, it is described on the same page as the original command. The “no” form of a 

command will mean one of the following:

• It can remove the configuration created by a command. For example, you create a VLAN with the vlan 

command, and you delete a VLAN with the no vlan command.

• It can reset a configuration value to its default. For example, you can create a static IGMP entry on a 

specified port of a specified VLAN with the ip multicast static-group command. You can remove the 
static IGMP entry from a specified port on a specified VLAN with the no ip multicast static-group 
command.

You may define substitute text for the switch’s CLI commands by using the 

 command. There are two 

main reasons for defining aliases:

• You can eliminate excess typing by reducing the number of characters required for a command.

To reduce the number of characters required to use the group term in a CLI command, you can change the 
syntax to gp as follows:

-> alias gp group

• You can change unfamiliar command words into familiar words or patterns.

If you prefer the term “privilege” to the term “attribute” with reference to a login account’s read-write 
capabilities, you can change the CLI word from attrib to privilege by using the following command.

-> alias privilege attrib

After an alias has been defined, both the alias and the original CLI term will be supported as valid CLI 
terms. For example if privilege is defined as an alias as shown above, both privilege and attrib will work 
as CLI commands and both words are shown when you use the CLI help feature.

You can save command aliases for the current user account by executing the 

 command. 

If the aliases are not saved they will be stored until the user session ends. In this case, once you log off the 
switch, substitute terms configured with the 

 command are destroyed.

 command. To set all alias values back to their factory defaults, use 

the
