LLDP
The
LLDP
webpage allows the user to inspect and configure the current LLDP interface settings as shown in Figure 2.84.
The page consists of
LLDP Parameters
and
LLDP Interface Configuration
. Table 2.69 summarizes the descriptions of the
LLDP Configuration
.

LLDP Parameters
Tx Interval
The switch periodically transmits LLDP frames to its neighbours 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.
30
Tx Hold
Each LLDP frame contains information about how long time 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.
4
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.
2
Tx Reinit
When an interface is disabled, LLDP is disabled or the switch is rebooted,
a LLDP shutdown frame is transmitted to the neighbouring units, signalling that
the LLDP information isn't valid anymore.
Tx Reinit
controls the number of seconds
between the shutdown frame and a new LLDP initialization. Valid values are
restricted to 1 - 10 seconds.

Interface
The switch interface name of the logical LLDP interface.
