Enable IEEE 802.1 Organizationally-Specific TLVs

This section describes how to configure IEEE 802.1 organizationally-specific TLVs for transmission when the transmission status is set to disabled by default.

  1. On both switches, configure VLAN name as VLAN 1.
    SEFOS# configure terminal
    SEFOS(config)# vlan 1
    SEFOS(config-vlan)# ports extreme-ethernet 0/1 name vlan1
    SEFOS(config-vlan)# end
  2. On both switches, enable IEEE 802.1 organizationally-specific TLVs.
    SEFOS# configure terminal
    SEFOS(config)# interface extreme-ethernet 0/1
    SEFOS(config-if)# lldp tlv-select dot1tlv port-vlan-id protocol-vlan-id all vlan-name all
    SEFOS(config)# end
  3. At switch 1, review the local system information.
    SEFOS# show lldp local extreme-ethernet 0/1
    Port Id SubType            : Interface Alias
    Port Id                : Slot0/1
    Port Description            : Ethernet Interface
    Enabled Tx Tlvs            : Port Vlan

    When the switch comes up, no protocol group is initially mapped to VLAN, so no entry is present in the VLAN module for the PPVID. A port and protocol VLAN entry is created in LLDP with the protocol VLAN ID value of 0, and the entry is transmitted after you enable PPVID TLV transmission.

  4. Review information about the learned neighbors on a particular interface.
    SEFOS# show lldp neighbors extreme-ethernet 0/1 detail
