Configuration of LLDP Neighbor MAC Address for LLDP Session

At Switch A and Switch B:

  1. Enable the LLDP module in both switches.

    Type the following:

    • Enter the Global Configuration Mode.
    iS5comm# configure terminal
    iS5comm(config)# set lldp enable
    iS5comm(config)# set lldp version v2
    At Switch A:
    • Configure the destination MAC address.
    iS5comm(config)# interface gigabitethernet  0/1
    iS5comm(config-if)# lldp dest-mac 00:02:02:03:04:01
    iS5comm(config)# exit
    At Switch B:
    • Configure the destination MAC address.
    iS5comm(config)# interface gigabitethernet  0/1
    iS5comm(config-if)# lldp dest-mac 00:01:02:03:04:01
    iS5comm(config)# exit
  2. At Switch A: verify the destination MAC address using the following command.

    Perform the following:

    iS5comm# show lldp interface gigabitethernet 0/1
    Gi0/1:
    Tx State            : Enabled
    Rx State            : Enabled
    Tx SEM State        : INITIALIZE
    Rx SEM State        : WAIT PORT OPERATIONAL
    Notification Status : Disabled
    Notification Type   : Mis-configuration
    DestinationMacAddr  : 01:80:c2:00:00:0e
    Gi0/1:
    Tx State            : Enabled
    Rx State            : Enabled
    Tx SEM State        : INITIALIZE
    Rx SEM State        : WAIT PORT OPERATIONAL
    Notification Status : Disabled
    Notification Type   : Mis-configuration
    DestinationMacAddr  : 00:02:02:03:04:01
  3. At Switch B: verify the destination MAC address using the following command.

    Perform the following:

    iS5comm# show lldp interface gigabitethernet 0/1
    Gi0/1:
    Tx State            : Enabled
    Rx State            : Enabled
    Tx SEM State        : INITIALIZE
    Rx SEM State        : WAIT PORT OPERATIONAL
    Notification Status : Disabled
    Notification Type   : Mis-configuration
    DestinationMacAddr  : 01:80:c2:00:00:0e
    Gi0/1:
    Tx State            : Enabled
    Rx State            : Enabled
    Tx SEM State        : INITIALIZE
    Rx SEM State        : WAIT PORT OPERATIONAL
    Notification Status : Disabled
    Notification Type   : Mis-configuration
    DestinationMacAddr  : 00:01:02:03:04:01
  4. Unmap the MAC address in both switches.

    Type the following:

    • Enter the Global Configuration Mode.
    iS5comm# configure terminal
    At Switch A:
    • Unmap the destination MAC address.
    iS5comm(config)# interface gigabitethernet  0/1
    iS5comm(config-if)# no lldp dest-mac 00:02:02:03:04:01
    iS5comm(config)# exit
    At Switch B:
    • Unmap the destination MAC address.
    iS5comm(config)# interface gigabitethernet  0/1
    iS5comm(config-if)# no lldp dest-mac 00:01:02:03:04:01
    iS5comm(config)# exit
  5. At Switch A: verify the destination MAC address using the following command.

    Perform the following:

    iS5comm# show lldp interface gigabitethernet 0/1
    Gi0/1:
    Tx State            : Enabled
    Rx State            : Enabled
    Tx SEM State        : INITIALIZE
    Rx SEM State        : WAIT PORT OPERATIONAL
    Notification Status : Disabled
    Notification Type   : Mis-configuration
    DestinationMacAddr  : 01:80:c2:00:00:0e
  6. At Switch B: verify the destination MAC address using the following command.

    Perform the following:

    iS5comm# show lldp interface gigabitethernet 0/1
    Gi0/1:
    Tx State            : Enabled
    Rx State            : Enabled
    Tx SEM State        : INITIALIZE
    Rx SEM State        : WAIT PORT OPERATIONAL
    Notification Status : Disabled
    Notification Type   : Mis-configuration
    DestinationMacAddr  : 01:80:c2:00:00:0e
