Step 3
lldp forward_message
(Optional) Enable the switch to forward LLDP messages when LLDP function is disabled.
Step 4
lldp hold-multiplier
(Optional) Specify the amount of time the neighbor device should hold the received
information before discarding it. The default is 4.
TTL (Time to Live) = Hold Multiplier * Transmit Interval.
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.
