Configuring LLDP

Changing the minimum time between port reinitializations

The LLDP re-initialization delay timer specifies the minimum number of seconds the device will wait
from when LLDP is disabled on a port, until it will honor a request to re-enable LLDP on that port.
When you enable LLDP, the system sets the re-initialization delay timer to two seconds. If desired,
you can change the default behavior from two seconds to a value between one and ten seconds.
The LLDP re-initialization delay timer ensures that there is a defined minimum amount of time
between successive LLDP frame transmission, thereby preventing a large number of LLDP frames
to be sent at one time.
To set the re-initialization delay timer, enter a command such as the following at the Global CONFIG
level of the CLI.
BigIron RX(config)#lldp reinit-delay 5
The above command causes the device to wait five seconds after LLDP is disabled, before
attempting to honor a request to re-enable it.
Syntax: [no] lldp reinit-delay <seconds>
where <seconds> is a value from 1 – 10. The default is two seconds.
