Field Description
Transmit Interval Specify the time between transmission of LLDPDUs. The range is from 5 to 32768 seconds
and the default is 30 seconds.
Transmit Hold
Multiplier
Specify the multiplier value on the transmit interval, which is used to compute the time-
to-live (TTL) value associated with LLDPDUs. The range is from 2 to 10 and the default
is 4.
Re-Initialization Delay Specify the number of seconds to wait before attempting to re-initialize LLDP on a port
after the LLDP operating mode on the port changes. The range is from 1 to 10 seconds and
the default is 2 seconds.
Notification Interval Specify the minimum number of seconds to wait between transmissions of remote data
change notifications. The range is from 5 to 3600 seconds and the default is 5 seconds.
Field Description
Interface The port or trunk ID.
Link Status The link status of the interface, which is either Up or Down. An interface that is down does
not forward traffic.
Transmit The LLDP advertise (transmit) mode on the interface. If the transmit mode is enabled, the
interface sends LLDPDUs that advertise the mandatory TLVs that are enabled.
