page to specify the message attributes for individual interfaces, including
whether messages are transmitted, received, or both transmitted and
received, whether SNMP notifications are sent, and the type of information
advertised.

PARAMETERS
These parameters are displayed:
◆ Admin Status – Enables LLDP message transmit and receive modes
for LLDP Protocol Data Units. (Options: Tx only, Rx only, TxRx,
Disabled; Default: TxRx)
◆ SNMP Notification – Enables the transmission of SNMP trap
notifications about LLDP and LLDP-MED changes. (Default: Disabled)
This option sends out SNMP trap notifications to designated target
stations at the interval specified by the Notification Interval in the
preceding section. Trap notifications include information about state
changes in the LLDP MIB (IEEE 802.1AB), the LLDP-MED MIB (ANSI/
TIA-1057), or vendor-specific LLDP-EXT-DOT1 and LLDP-EXT-DOT3
MIBs.
For information on defining SNMP trap destinations, see "Specifying
Trap Managers" on page 415.
Information about additional changes in LLDP neighbors that occur
between SNMP notifications is not transmitted. Only state changes that
exist at the time of a trap notification are included in the transmission.
An SNMP agent should therefore periodically check the value of
lldpStatsRemTableLastChangeTime to detect any lldpRemTablesChange
notification-events missed due to throttling or transmission loss.
