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 
    --------------------------------------------------------------------
