Configuration procedure
1) Configure Switch A.
# Enable LLDP globally.
<SwitchA> system-view
[SwitchA] lldp enable
# Enable LLDP on GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2, setting the LLDP operating mode to
Rx.
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] lldp enable
[SwitchA-GigabitEthernet1/0/1] lldp admin-status rx
[SwitchA-GigabitEthernet1/0/1] quit
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] lldp enable
[SwitchA-GigabitEthernet1/0/2] lldp admin-status rx
[SwitchA-GigabitEthernet1/0/2] quit
2) Configure Switch B.
# Enable LLDP globally.
<SwitchB> system-view
[SwitchB] lldp enable
# Enable LLDP on GigabitEthernet1/0/1, setting the LLDP operating mode to Tx.
[SwitchB] interface gigabitethernet 1/0/1
[SwitchB-GigabitEthernet1/0/1] lldp enable
[SwitchB-GigabitEthernet1/0/1] lldp admin-status tx
[SwitchB-GigabitEthernet1/0/1] quit
3) Verify the configuration.
# Display the global LLDP status and port LLDP status on Switch A.
[SwitchA] display lldp status
