Usage Guide:
After configuring the interval of sending messages, LLDP messages can only be received after a
period as long as configured. The interval should be less than or equal with half of aging time, for a
too long interval will cause the state of being aged and reconstruction happen too often; while a too
short interval will increase the flow of the network and decrease the bandwidth of the port. The value
of the aging time of messages is the product of the multiplier and the interval of sending messages.
The maximum aging time is 65535 seconds.
When tx-interval is the default value and transmit delay is configured via some commands,
tx-interval will become four times of the latter, instead of the default 40.
Example:
Set the interval of sending messages as 40 seconds.
Switch(config)# lldp tx-interval 40
