The page includes the following fields:
LLDP Parameters
Object Description
• Tx Interval
The switch is periodically transmitting LLDP frames to its
neighbors for having the network discovery information
up-to-date. The interval between each LLDP frame is determined
by the Tx Interval value. Valid values are restricted to 5 - 32768
seconds.
Default: 30 seconds
This attribute must comply with the following rule:
(Transmission Interval * Hold Time Multiplier) ≤65536, and
Transmission Interval >= (4 * Delay Interval)
• Tx Hold
Each LLDP frame contains information about how long the
information valid period is set to Tx Hold multiplied by Tx
Interval seconds. Valid values are restricted to 2 - 10 times.
TTL in seconds is based on the following rule:
(Transmission Interval * Holdtime Multiplier) ≤ 65536.
Therefore, the default TTL is 4*30 = 120 seconds.
• Tx Delay
If some configuration is changed (e.g. the IP address) a new LLDP
frame is transmitted, but the time between the LLDP frames will
always be at least the value of Tx Delay seconds. Tx Delay cannot
be larger than 1/4 of the Tx Interval value. Valid values are
restricted to 1 - 8192 seconds.
This attribute must comply with the rule:
(4 * Delay Interval) ≤Transmission Interval
• Tx Reinit
When a port is disabled, LLDP is disabled or the switch is
rebooted a LLDP shutdown frame is transmitted to the
neighboring units, signaling that the LLDP information isn't valid
anymore. Tx Reinit controls the amount of seconds between the
shutdown frame and a new LLDP initialization. Valid values are
restricted to 1 - 10 seconds.
LLDP Port Configuration
The LLDP port settings relate to the currently selected stack unit, as reflected by the page header.
