Configuring LLDP Interface Attributes

CLI – This example several attributes which control basic LLDP message timing.
Configuring LLDP Interface Attributes
Use the LLDP Port/Trunk Configuration 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.
Command Attributes
• Admin Status – Enables LLDP message transmit and receive modes for LLDP
Protocol Data Units. (Options: Tx only, Rx only, RxTx, Disabled; Default: RxTx)
• SNMP Notification – Enables the transmission of SNMP trap notifications about
LLDP 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), or vendor-specific LLDP-EXT-DOT1 and LLDP-EXT-DOT3 MIBs.
For information on defining SNMP trap destinations, see “Specifying Trap
Managers and Trap Types” on page 5-3.
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.
• TLV Type – Configures the information included in the TLV field of advertised
messages.
- Port Description – The port description is taken from the ifDescr object in
RFC 2863, which includes information about the manufacturer, the product
name, and the version of the interface hardware/software.
