Data Type Configuration
Options
Default Description
1
The Packet Time-to-Live value is included in LLDP data packets. (Refer to “Changing the Time-to-Live for Transmitted
Advertisements” on page 14-45.)
2
Subelement of the Chassis ID TLV.
3
Subelement of the Port ID TLV.
4
Subelement of the Remote-Management-Address TLV.
5
Subelement of the System Capability TLV.

Populated with data captured internally by the switch. For more on these data types, refer to the IEEE P802.1AB Standard.
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. Refer to “IP
Address Advertisements” on page 14-40.
Debug Logging. You can enable LLDP debug logging to a configured debug
destination (Syslog server and/or a terminal device) by executing the
debug
lldp
command. (For more on Debug and Syslog, refer to 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 (page 14-41).
■ Using an SNMP application that is designed to query the Neighbors
MIB for LLDP data to use in device discovery and topology mapping.
3400/6400 only?
■ Using the
walkmib
command to display a listing of the LLDP MIB
objects
