Configuration procedure
1. Configure Switch A:
# Enable LLDP globally.
system-view
[SwitchA] lldp global enable
# Enable LLDP on GigabitEthernet 1/0/1. By default, LLDP is enabled on ports.
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] lldp enable
# Set the LLDP operating mode to Rx.
[SwitchA-GigabitEthernet1/0/1] lldp admin-status rx
[SwitchA-GigabitEthernet1/0/1] quit
# Enable LLDP on GigabitEthernet 1/0/2. By default, LLDP is enabled on ports.
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] lldp enable
# Set the LLDP operating mode to Rx.
[SwitchA-GigabitEthernet1/0/2] lldp admin-status rx
[SwitchA-GigabitEthernet1/0/2] quit
2. Configure Switch B:
# Enable LLDP globally.
system-view
[SwitchB] lldp global enable
# Enable LLDP on GigabitEthernet 1/0/1. By default, LLDP is enabled on ports.
[SwitchB] interface gigabitethernet 1/0/1
[SwitchB-GigabitEthernet1/0/1] lldp enable
# Set the LLDP operating mode to Tx.
[SwitchB-GigabitEthernet1/0/1] lldp admin-status tx
[SwitchB-GigabitEthernet1/0/1] quit
Verify the configuration:
# Verify that:
• GigabitEthernet 1/0/1 of Switch A connects to a MED device.
• GigabitEthernet 1/0/2 of Switch A connects to a non-MED device.
• Both ports operate in Rx mode, and they can receive LLDP frames but cannot send LLDP frames.
