xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch CLI Reference Guide
484
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.
