Setting the LLDP operating mode
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2/Layer 3
Ethernet interface view,
management Ethernet
interface view, or Layer
2/Layer 3 aggregate
interface view.
interface interface-type interface-number N/A
3. Set the LLDP operating
mode.
• In Layer 2/Layer 3 Ethernet interface
view or management Ethernet interface
view:
lldp [ agent { nearest-customer |
nearest-nontpmr } ] admin-status
{ disable | rx | tx | txrx }
• In Layer 2/Layer 3 aggregate interface
view:
lldp agent { nearest-customer |
nearest-nontpmr } admin-status { disable
| rx | tx | txrx }
By default:
• The nearest bridge
agent operates in txrx
mode.
• The nearest customer
bridge agent and
nearest non-TPMR
bridge agent operate in
disable mode.
In Ethernet interface view, if
no agent type is specified,
the command configures
the operating mode for
nearest bridge agents.
In aggregate interface
view, you can configure the
operating mode only for
nearest customer bridge
agents and nearest
non-TPMR bridge agents.
Setting the LLDP reinitialization delay
When the LLDP operating mode changes on a port, the port initializes the protocol state machines after
an LLDP reinitialization delay. By adjusting the delay, you can avoid frequent initializations caused by
frequent changes to the LLDP operating mode on a port.
To set the LLDP reinitialization delay for ports:
Step Command Remarks
1. Enter system view. system-view N/A
2. Set the LLDP reinitialization
delay.
lldp timer reinit-delay delay The default setting is 2 seconds.
Enabling LLDP polling
With LLDP polling enabled, a device periodically searches for local configuration changes. When the
device detects a configuration change, it sends LLDP frames to inform neighboring devices of the change.
