Description
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)
Each LLDP frame contains information about how long the information
in the LLDP frame shall be considered valid. The LLDP 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.
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
