The delay is applied to only the following traps: traps for adding neighbors, traps for deleting
neighbors, neighbor aging traps, and traps for discarding neighbor packets
(LLDP_1.0.8802.1.1.2.0.0.1 lldpRemTablesChange).
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
lldp message-transmission interval interval
The interval for sending LLDP packets is set.
By default, the interval for sending LLDP packets is 30 seconds.
Step 3 Run:
lldp message-transmission delay delay
The delay to send LLDP packets is set.
By default, the delay to send LLDP packets is 2 seconds.
Step 4 Run:
lldp message-transmission hold-multiplier hold
The hold time multiplier of device information stored on neighbors is set.
The default value is 4.
NOTE
l You can extend the storage time of device information on the neighbors by increasing the value of
hold.
l The value of hold ranges from 2 to 10; however, when the value of (hold x interval) is greater than
65535, the hold value is invalid.
Step 5 Run:
lldp restart-delay delay
The delay to re-enable LLDP on an interface is set.
The default value is 2, in seconds.
If LLDP is disabled on an interface, the system re-enables LLDP for the interface after a delay.
Step 6 Run:
lldp trap-interval interval
The delay to send neighbor change traps to the NMS is set.
The default value is 5, in seconds.
----End
2.3.7 (Optional) Enabling the LLDP Trap Function
To send traps to the NMS when the neighbor information changes, you need to enable the LLDP
trap function on the switch.
