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 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.
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LLDP information is no longer valid.
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 current unit, as reflected by the page header.
Object Description
Port
The switch port number of the logical LLDP port.
Mode
Select LLDP mode.
Rx only
The switch will not send out LLDP information, but LLDP
information from neighbor units is analyzed.
Tx only
The switch will drop LLDP information received from neighbors, and
will send out LLDP information.
Disabled
The switch will not send out LLDP information, and will drop LLDP
information received from neighbors.
Enabled
The switch will send out LLDP information, and will analyze LLDP
information received from neighbors.
