vlan command

This command configures and displays the VLAN (virtual local area network) settings for the CMM.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or vlan command errors for a list of error messages that are specific to the vlan command.

Note: When viewing the vlan entries, settings preceded by an option (for example, -i) can be modified and settings preceded by a label (for example, IPv4 address:) are fixed.
Table 1. vlan command.

The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.

Example:

To display all VLAN settings, while the CMM in bay 2 is set as the persistent command environment, at the system:mm[2]> prompt, type 
vlan
To disable the global VLAN state, while the CMM in bay 2 is set as the persistent command environment, at the system:mm[2]> prompt, type 
vlan -state disabled
To delete the VLAN entry with an index number of 2, while the CMM in bay 2 is set as the persistent command environment, at the system:mm[2]> prompt, type 
vlan -delete -vi 2
To apply (commit) all changes made to VLAN settings, while the CMM in bay 2 is set as the persistent command environment, at the system:mm[2]> prompt, type 
vlan -commit
To display the VLAN settings for the compute node with a VLAN ID of 1, while the CMM in bay 2 is set as the persistent command environment, at the system:mm[2]> prompt, type 
vlan -vi 1
