## Enable an Existing VLAN Name

If you delete, then recreate, a VLAN, the VLAN name TLV transmission status is disabled. Use the instructions in this section to re-enable the VLAN name for transmission.

1. At switch 1, delete the VLAN (`2` in this example) that is enabled for transmission:

       SEFOS# configure terminal
       SEFOS(config)# no vlan 2
       SEFOS(config)# end

2. Review the local system and learned neighbor information.

       SEFOS# show lldp local extreme-ethernet 0/1
       ...
       -Vlan Name
       Vlan Id        Vlan Name                    TxStatus
       -------        ---------                    --------
       1            vlan1                        Enabled
       --------------------------------------------------------------------

   The entry corresponding to `VLAN 2` is not displayed because the transmission has not been enabled.

3. At switch 2, review the learned neighbor information on the `extreme-ethernet 0/1` interface.

       SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
       ...
       -Vlan Name
       Vlan Id                Vlan Name
       -------                ---------
       1                    vlan1
       ------------------------------------------------------------

       Total Entries Displayed        : 1

   The entry corresponding to `VLAN 2` is not displayed because transmission has not been enabled.

4. At switch 1, recreate the VLAN with the VLAN ID set to 2, the VLAN name set to `vlan 2`, and the `extreme-ethernet 0/1` interface as member port.

       SEFOS# configure terminal
       SEFOS(config)# vlan 2
       SEFOS(config-vlan)# ports extreme-ethernet 0/1 name vlan2
       SEFOS(config-vlan)# end

5. Review the TLV transmission status of the VLAN names in the local system information.

       SEFOS# show lldp local extreme-ethernet 0/1
       ...
       -Vlan Name
       Vlan Id        Vlan Name                    TxStatus
       -------        ---------                    --------
       1            vlan1                        Enabled
       2            vlan2                        Disabled
       --------------------------------------------------------------------
