Description
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.
Synopsis: 5 to 32768 s
Default: 30 s
The interval at which LLDP frames are transmitted on behalf of this LLDP agent.
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))
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.
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)
