Configuration of LLDP VID Digest

LLDP VID Digest is a new TLV supported for compliance with LLDP specification 802.1AB-2009. Refer to Section 3.2 for LLDP-V2 Topology.

At Switch A, B, C & D:

  1. Enable the LLDP Version 2 on all switches.

    Type the following:

    • Enter the Global Configuration Mode.
    iS5comm# configure terminal
    iS5comm(config)# set lldp enable
    iS5comm(config)# set lldp version v2
  2. At Switch A: Enable Management VID in the switch.

    Type the following:

    • Configure the destination MAC address.
    iS5comm(config)# interface gigabitethernet  0/1
    iS5comm(config-if)# lldp tlv-select dot1tlv vid-usage-digest
    iS5comm(config-if)# lldp tlv-select dot1tlv mgmt-vid
    iS5comm(config-if)# end
    • Verify the management VID using the show command as given below.
    iS5comm# show lldp local gigabitethernet  0/1
