Using the CLI

This example shows how the Prefix Recognition feature is used for entering multiple commands that have 
the same prefix. This table lists the tasks to be accomplished in this example and the CLI syntax required 
for each task.

To create VLAN 501 and configure its attributes using the CLI commands, you could enter the vlan 501 
prefix three times. However, VLAN commands support the prefix recognition capability so redundant 
entry of this prefix is not necessary.

For example, when you enter

-> vlan 501 enable

the CLI will automatically store the prefix vlan 501. Now, if you enter a related command for the same 
VLAN, you are only required to enter suffix information. In this case, you can enter the commands to 
accomplish tasks 2, and 3 as follows:

-> stp enable

-> authentication enable

Prefix information will be remembered by the CLI until you enter a command with a new prefix.

Note. If you want to create or configure another VLAN, you must reenter the full command prefix, 
including the new VLAN ID.

You can view the current prefix by issuing the 

 command. If you issue this command when 

the prefix stored by the CLI is vlan 501 the following will display.

-> show prefix

Current prefix: vlan 501

If you issue the show prefix command when there is no prefix stored by the CLI, a “no prefix” message 
will display.

1. Create a VLAN with an identification number of 501.

2. Enable the spanning tree protocol for VLAN 501.

3. Enable authentication for VLAN 501.
