Changing the reinitialization delay interval (CLI)
Syntax:
setmib lldpReinitDelay.0 -i <1-10>
Uses
setmib
to change the minimum time (reinitialization delay interval) an LLDP port will wait before
reinitializing after receiving an LLDP disable command followed closely by a txonly or tx_rx command. The delay
interval commences with execution of the
lldp admin-status port-list disable
command.
(Default: 2 seconds; Range 1–10 seconds)
Example:
The following command changes the reinitialization delay interval to five seconds:
switch(config)# setmib lldpreinitdelay.0 -i 5
Configuring SNMP notification support
You can enable SNMP trap notification of LLDP data changes detected on advertisements received from neighbor
devices, and control the interval between successive notifications of data changes on the same neighbor.
Enabling LLDP data change notification for SNMP trap receivers (CLI)
Syntax:
[no] lldp enable-notification <
port-list
>
Enables or disables each port in
port-list
for sending notification to configured SNMP trap receivers if an LLDP
data change is detected in an advertisement received on the port from an LLDP neighbor.
(Default: Disabled)
For information on configuring trap receivers in the switch, see
on page 194.
Example:
This command enables SNMP notification on ports 1 - 5:
switch(config)# lldp enable-notification 1-5
Changing the minimum interval for successive data change notifications for the same
neighbor
If LLDP trap notification is enabled on a port, a rapid succession of changes in LLDP information received in
advertisements from one or more neighbors can generate a high number of traps. To reduce this effect, you can
globally change the interval between successive notifications of neighbor data change.
Syntax:
setmib lldpnotificationinterval.0 -i <
1-3600
>
Globally changes the interval between successive traps generated by the switch. If multiple traps are generated in
the specified interval, only the first trap is sent. The remaining traps are suppressed. (A network management
application can periodically check the switch MIB to detect any missed change notification traps. See IEEE
P802.1AB or later for more information.)
(Default: 5 seconds)
Example:
The following command limits change notification traps from a particular switch to one per minute.
