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
