Advertisement

switch(config)# lldp holdtime-multiplier 2
Delay interval between advertisements generated by value or status changes to the
LLDP MIB
The switch uses a delay-interval setting to delay transmitting successive advertisements resulting from these
LLDP MIB changes. If a switch is subject to frequent changes to its LLDP MIB, lengthening this interval can
reduce the frequency of successive advertisements. You can change the delay-interval by using either an SNMP
network management application or the CLI setmib command.
Changing the delay interval between advertisements generated by value or status
changes to the LLDP MIB (CLI)
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)
NOTE: The LLDP refresh-interval (transmit interval) must be greater than or equal to (4 x delay-
interval). The switch does not allow increasing the delay interval to a value that conflicts with this
relationship. That is, the switch displays Inconsistent value if (4 x delay-interval) exceeds the
current transmit interval, and the command fails. Depending on the current refresh-interval setting, it
may be necessary to increase the refresh-interval before using this command to increase the delay-
interval.
Example:
To change the delay-interval from 2 seconds to 8 seconds when the refresh-interval is at the default 30 seconds,
you must first set the refresh-interval to a minimum of 32 seconds (32 = 4 x 8) as shown in the following image.

Reinitialization delay interval
In the default configuration, a port receiving a disable command followed immediately by a txonly, rxonly, or
tx_rx command delays reinitializing for two seconds, during which LLDP operation remains disabled. If an active
port is subjected to frequent toggling between the LLDP disabled and enabled states, LLDP advertisements are
more frequently transmitted to the neighbor device. Also, the neighbor table in the adjacent device changes more
frequently as it deletes, then replaces LLDP data for the affected port which, in turn, generates SNMP traps (if
trap receivers and SNMP notification are configured). All of this can unnecessarily increase network traffic.
Extending the reinitialization-delay interval delays the ability of the port to reinitialize and generate LLDP traffic
following an LLDP disable/enable cycle.
