Configuring or changing static VLAN per-port settings (CLI)

Syntax: 


vlan <vid>

no vlan <vid>

This command, used with the options listed below, changes the name of an existing static VLAN and the per-port VLAN membership settings.

NOTE:

You can use these options from the configuration level by beginning the command with vlan <vid>, or from the context level of the specific VLAN by just entering the command option. 


tagged <port-list>

Configures the indicated port as Tagged for the specified VLAN. The no version sets the port to either No or (if GVRP is enabled) to Auto. 


untagged <port-list>

Configures the indicated port as Untagged for the specified VLAN. The no version sets the port to either No or (if GVRP is enabled) to Auto. 


forbid <port-list>

Used in port-based VLANs, configures <port-list> as forbidden to become a member of the specified VLAN, as well as other actions. Does not operate with option not allowed protocol VLANs. The no version sets the port to either No or (if GVRP is enabled) to Auto. See GVRP. 


auto <port-list>

Available if GVRP is enabled on the switch. Returns the per-port settings for the specified VLAN to Auto operation. Auto is the default per-port setting for a static VLAN if GVRP is running on the switch. For information on dynamic VLAN and GVRP operation, see GVRP.

Changing the VLAN name and set ports to tagged

Suppose that there is a VLAN named VLAN100 with a VID of 100 and all ports are set to No for this VLAN. To change the VLAN name to Blue_Team and set ports A1 - A5 to Tagged, use the following commands: 

switch(config)# vlan 100 name Blue_Team 
switch(config)# vlan 100 tagged a1-a5

Moving the context level

To move to the vlan 100 context level and execute the same commands: 

switch(config)# vlan 100 
switch(vlan-100)# name Blue_Team 
switch(vlan-100)# tagged a1-a5

Changing tagged ports

Similarly, to change the tagged ports in the above examples to No (or Auto, if GVRP is enabled), use either of the following commands.

At the global config level, use: 

switch(config)# no vlan 100 tagged a1-a5

or

At the VLAN 100 context level, use: 

switch(vlan-100)# no tagged a1-a5
NOTE:

You cannot use these commands with dynamic VLANs. Attempting to do so displays the message VLAN already exists with no change.
