Management and Configuration Guide K/KA/KB.15.15

The switch preserves the current LLDP configuration when LLDP is disabled. After LLDP is disabled,
the information in the LLDP neighbors database remains until it times-out.
(Default: Enabled)
Example
To disable LLDP on the switch:
(HP_Switch_name#) no lldp run
Changing the packet transmission interval
This interval controls how often active ports retransmit advertisements to their neighbors.
Syntax
lldp refresh-interval <5 - 32768>
Changes the interval between consecutive transmissions of LLDP advertisements on any given port.
(Default: 30 seconds)
NOTE: The refresh-interval must be greater than or equal to (4 x delay-interval.)
(The default delay-interval is 2.) For example, with the default delay-interval, the lowest
refresh-intervalyou can use is 8 seconds (4 x 2=8.) Thus, if you want a refresh-interval
of 5 seconds, you must first change the delay interval to 1 (that is, 4 x 1 5.) If you want to change
the delay-interval, use the setmib command.
Changing the time-to-live for transmitted advertisements
Syntax
lldp holdtime-multiplier 2 - 10
Changes the multiplier an LLDP switch uses to calculate the Time-to-Live for the LLDP advertisements
it generates and transmits to LLDP neighbors. When the Time-to-Live for a given advertisement
expires, the advertised data is deleted from the neighbor switch's MIB.
(Default: 4; Range 2–10)
Example
If the refresh-interval on the switch is 15 seconds and the holdtime-multiplier is at the default,
the Time-to-Live for advertisements transmitted from the switch is 60 seconds (4 x 15.)
To reduce the Time-to-Live, you could lower the holdtime-interval to 2, which would result
in a Time-to-Live of 30 seconds.
(HP_Switch_name#) lldp holdtime-multiplier 2
Changing the delay interval
To change the delay interval between advertisements generated by value or status changes to the
LLDP MIB, use the following command.
Syntax
setmib lldpTxDelay.0 -i 1 - 8192
Uses setmib to change the minimum time (delay-interval) any LLDP port will delay advertising
successive LLDP advertisements because of a change in LLDP MIB content.
(Default: 2; Range 1–8192)
