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
8.5 lldp msgTxHold
Command:
lldp msgTxHold <value>
no lldp msgTxHold
Function:
Set the multiplier value of the aging time carried by update messages sent by the all ports with
LLDP function enabled, the value ranges from 2 to 10.
Parameters:
<value> is the aging time multiplier, ranging from 2 to 10.
Default:
the value of the multiplier is 4 by default.
Command Mode:
Global Mode.
Usage Guide:
After configuring the multiplier, the aging time is defined as the product of the multiplier and the
interval of sending messages, and its maximum value is 65535 seconds.
Example:
Set the value of the aging time multiplier as 6.
Switch(config)#lldp msgTxHold 6
8.6 lldp transmit delay
Command:
lldp transmit delay <seconds>
no lldp transmit delay
Function:
Since local information might change frequently because of the variability of the network
environment, there could be many update messages sent in a short time. So a delay is required to
guarantee an accurate statistics of local information.
When transmit delay is the default value and tx-interval is configured via some commands, transmit
delay will become one fourth of the latter, instead of the default 2.
