1
The Packet Time-to-Live value is included in LLDP data packets.
2
Subelement of the Chassis ID TLV.
3
Populated with data captured internally by the switch. For more on these data types, refer to the IEEE P802.1AB Standard.
4
Subelement of the Port ID TLV.
5
Subelement of the Remote-Management-Address TLV.
6
Subelement of the System Capability TLV.
Remote management address
The switch always includes an IP address in its LLDP advertisements. This can be either an address selected by
a default process or an address configured for inclusion in advertisements. See IP address advertisements on
page 176.
Debug logging
You can enable LLDP debug logging to a configured debug destination (Syslog server, a terminal device, or both)
by executing the debug lldp command. (For more information on Debug and Syslog, see the "Troubleshooting"
appendix in this guide.) Note that the switch's Event Log does not record usual LLDP update messages.
Options for reading LLDP information collected by the switch
You can extract LLDP information from the switch to identify adjacent LLDP devices. Options include:
• Using the switch's show lldp info command options to display data collected on adjacent LLDP devices—
as well as the local data the switch is transmitting to adjacent LLDP devices (Displaying the global LLDP,
port admin, and SNMP notification status (CLI) on page 176).
• Using an SNMP application that is designed to query the Neighbors MIB for LLDP data to use in device
discovery and topology mapping.
• Using thewalkmib command to display a listing of the LLDP MIB objects
LLDP and LLDP-MED standards compatibility
The operation covered by this section is compatible with these standards:
• IEEE P802.1AB
• RFC 2922 (PTOPO, or Physical Topology MIB)
• RFC 2737 (Entity MIB)
• RFC 2863 (Interfaces MIB)
• ANSI/TIA-1057/D6 (LLDP-MED; refer to LLDP-MED (media-endpoint-discovery) on page 187.)
