## Enable a Particular PPVID

The PPDVID TLV transmission status is disabled by default. If you configure a new PPVID, the TLV transmission status of the VLAN name is disabled by default. If you configure a new PPVID, the PPVID is not transmitted by default (the TLV transmission status of the newly configured PPVID is disabled).

1. At switch 1, create and map protocols-group 10 to `VLAN 2`.

       SEFOS# configure terminal
       SEFOS(config)# map protocol ip enet-v2 protocols-group 10
       SEFOS(config)# interface extreme-ethernet 0/1
       SEFOS(config-if)# switchport map protocols-group 10 vlan 2
       SEFOS(config-if)# end

2. Review the local system information.

       SEFOS# show lldp local extreme-ethernet 0/1
       ...
       Extended 802.1 TLV Info
       -Port VLAN Id                : 1
       -Port & Protocol VLAN Id
       Protocol VLAN Id   Support   Protocol VLAN Status   TxStatus
       ----------------   -------    --------------------   --------
       2            Supported    Enabled        Disabled
       ...

3. Enable the transmission of protocol VLAN ID TLVs.

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/1
       SEFOS(config-if)# lldp tlv-select dot1tlv port-vlan-id protocol-vlan-id 2
       SEFOS(config)# end

4. Review the local system information.

       SEFOS# show lldp local extreme-ethernet 0/1
       ...
       Extended 802.1 TLV Info
       -Port VLAN Id                : 1
       -Port & Protocol VLAN Id
       Protocol VLAN Id  Support   Protocol VLAN Status   TxStatus
       ----------------  -------   --------------------   -------
       2             Supported   Enabled           Enabled

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

       SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
       ...
       Extended 802.1 TLV Info
       -Port VLAN Id            : 1
       -Port & Protocol VLAN Id
       Protocol Vlan Id        Support            Status
       ----------------        -------            ------
       2                Supported            Enabled
       ...

6. At switch 1, delete the PPVID (that is, unmap protocols-group 10 in the `extreme-ethernet 0/1` interface).

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/1
       SEFOS(config-if)# no switchport map protocols-group 10
       SEFOS(config)# end

7. Review the local system information.

       SEFOS# show lldp local extreme-ethernet 0/1
       ...
       Extended 802.1 TLV Info
       -Port VLAN Id                    : 1
       -Port & Protocol VLAN Id
       Protocol VLAN Id   Support   Protocol VLAN Status   TxStatus
       ----------------   -------   --------------------   --------
       0            Supported   Enabled              Disabled
       ...

   No entry is displayed for the port-and-protocol VLAN ID.

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

       SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
       ...
       Extended 802.1 TLV Info
       -Port VLAN Id            : 1
       -Port & Protocol VLAN Id
       Protocol Vlan Tlv            : Not Advertised
       ...

   No entry is displayed for the port-and-protocol VLAN ID.

9. At switch 1, recreate the PPVID (that is, create and map protocols-group 10 to `VLAN 2`).

       SEFOS# configure terminal
       SEFOS(config)# map protocol ip enet-v2 protocols-group 10
       SEFOS(config)# interface extreme-ethernet 0/1
       SEFOS(config-if)# switchport map protocols-group 10 vlan 2
       SEFOS(config-if)# end

10. Review the local system information.

        SEFOS# show lldp local extreme-ethernet 0/1
        ...
        Extended 802.1 TLV Info
        -Port VLAN Id                : 1
        -Port & Protocol VLAN Id
        Protocol VLAN Id   Support   Protocol VLAN Status   TxStatus
        ----------------   -------   --------------------   --------
        2            Supported   Enabled              Disabled
        ...

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

        SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
        ...
        Extended 802.1 TLV Info
        -Port VLAN Id                : 1
        -Port & Protocol VLAN Id
        Protocol Vlan Tlv            : Not Advertised
        ...
