Parameter
Description
State
Synopsis:
{ Disabled, Enabled }
Default:
Enabled
Enables LLDP protocol. Note that LLDP is enabled on a port when
LLDP is enabled globally and along with enabling per port setting
in Port LLDP Parameters menu.
Tx Interval
Synopsis:
5 to 32768 s
Default:
30 s
The interval at which LLDP frames are transmitted on behalf of
this LLDP agent.
Tx Hold
Synopsis:
2 to 10
Default:
4
The multiplier of the Tx Interval parameter that determines the
actual time-to-live (TTL) value used in a LLDPDU. The actual TTL
value can be expressed by the following formula:
TTL = MIN(65535, (Tx Interval * Tx Hold))
Reinit Delay
Synopsis:
1 to 10 s
Default:
2 s
The delay in seconds from when the value of Admin Status
parameter of a particular port becomes 'Disbled' until re-
initialization will be lattempted.
Tx Delay
Synopsis:
1 to 8192 s
Default:
2 s
The delay in seconds between successive LLDP frame
transmissions initiated by value or status changed. The
recommended value is set by the following formula:
1 <= txDelay <= (0.25 * Tx Interval)
