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 you
do not specify an agent type, the
command sets the operating
mode for nearest bridge agents.
In aggregate interface view, you
can set the operating mode only
for nearest customer bridge
agents and nearest non-TPMR
bridge agents.
In IRF physical interface view,
you can set the operating mode
only for nearest 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.

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.
To enable LLDP polling:
