Performing basic LLDP configuration

Enabling LLDP

To make LLDP take effect on specific ports, you must enable LLDP both globally and on these ports.

To enable LLDP:

Step Command Remarks

1. Enter system view.

system-view N/A

2. Enable LLDP globally.

lldp global enable

By default, LLDP is disabled

globally.

3. Enter Layer 2 or Layer 3

Ethernet interface view.

interface interface-type interface-number N/A

4. (Optional.) Enable LLDP.

lldp enable

By default, LLDP is enabled

on a port.

Configuring the LLDP bridge mode

The following LLDP bridge modes are available: service bridge mode and customer bridge mode.

• In service bridge mode, LLDP supports nearest bridge agents and nearest non-TPMR bridge agents.

LLDP processes the LLDPDUs with destination MAC addresses for these agents and transparently

transmits the LLDPDUs with other destination MAC addresses in the VLAN.
