config lldp
Description
This command is used to configure LLDP timer values. The message TX interval controls how often
active ports retransmit advertisements to their neighbors. The message TX hold multiplier is a
multiplier on the msgTxInterval that is used to compute the TTL value of txTTL in an LLDPDU. The
TTL will be carried in the LLDPDU packet. The lifetime will be the minimum of 65535 and
(message_tx_interval * message_tx_hold_multiplier). On the partner switch, when the time-to-live for a
given advertisement expires, the advertised data is deleted from the neighbor switch’s MIB. The TX
delay is used to change the minimum time (delay-interval) any LLDP port will delay advertising
successive LLDP advertisements due to a change in LLDP MIB content. The TX delay defines the
minimum interval between sending of LLDP messages due to the constantly changing MIB content. A
re-enabled LLDP port will wait for the reinit delay after the last disable command before reinitializing.
Format
config lldp [message_tx_interval <sec 5-32768> | message_tx_hold_multiplier <int 2-10> |
tx_delay <sec 1-8192> | reinit_delay <sec 1-10>]
Parameters
message_tx_interval
- Specify the message TX interval between consecutive transmissions of
LLDP advertisements on any given port.
<sec 5-32768>
- The range is from 5 to 32768 seconds. The default setting is 30 seconds.
message_tx_hold_multiplier
- Specify the message TX hold multiplier.
<int 2-10>
- Specify the range is from 2 to 10. The default setting is 4.
tx_delay
- Specify the TX delay time.
<sec 1-8192>
- Specify the range is from 1 to 8192 seconds. The default setting is 2 seconds.
Note:
txDelay should be less than or equal to 0.25 * msgTxInterval.
reinit_delay
- Specify the reinit delay time.
<sec 1-10>
- Specify the range is from 1 to 10 seconds. The default setting is 2 seconds.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To change the packet transmission interval:
DGS-3420-28SC:admin#config lldp message_tx_interval 30
Command: config lldp message_tx_interval 30
Success.
DGS-3420-28SC:admin#
To change the multiplier value:
