Changing the Transmission Interval for LLDP Packets. 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-
interval you 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. (Refer to page 13-40.)
Changing the Time-to-Live for Transmitted Advertisements. The
Time-to-Live value (in seconds) for all LLDP advertisements transmitted from
a switch is controlled by the switch that generates the advertisement, and
determines how long an LLDP neighbor retains the advertised data before
discarding it. The Time-to-Live value is the result of multiplying the refresh-
interval by the holdtime-multiplier described below.
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)
For 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.
