Configuring LLDP LLDP Configurations
Step 3 lldp forward_message
(Optional) Enable the switch to forward LLDP messages when LLDP function is disabled.
Step 4 lldp hold-multiplier
multiplier
(Optional) Specify the amount of time the neighbor device should hold the received
information before discarding it. This parameter is a multiplier on the Transmit Interval that
determines the actual TTL (Time To Live) value used in an LLDP packet. TTL is the duration
that the neighbor device should hold the received LLDP packet before discarding it.
TTL= Hold Multiplier * Transmit Interval.
multiplier:
Specify the hold-multiplier. The valid value ranges from 2 to 10, and the default
value is 4.
Step 5 lldp timer { tx-interval
tx-interval
| tx-delay
tx-delay
| reinit-delay
reinit-delay
| notify-
interval
notify-interval
| fast-count
fast-count
}
(Optional) Configure the timers for LLDP packet forwarding.
tx-interval:
Enter the interval between successive LLDP packets that are periodically sent
from the local device to its neighbors.
tx-delay:
Specify the amount of time that the local device waits before sending another
LLDP packet to its neighbors. The default is 2 seconds.
reinit-delay:
Specify the amount of time that the local device waits before sending another
LLDP packet to its neighbors. The default is 2 seconds.
notify-interval:
Enter the interval between successive Trap messages that are periodically
sent from the local device to the NMS. The default is 5 seconds.
fast-count:
Specify the number of packets that the local port sends when its Admin Status
changes. The default is 3.
Step 6 show lldp
Display the LLDP information.
Step 7 end
Return to Privileged EXEC Mode.
Step 8 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to configure the following parameters, lldp timer=4,
tx-interval=30 seconds, tx-delay=2 seconds, reinit-delay=3 seconds, notify-iInterval=5
seconds, fast-count=3.
