Options For Reading Lldp Information Collected By The Switch - HP ProCurve 6400cl Series Management And Configuration Manual

Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)

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 14-31.
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 the Management and Configuration Guide for your switch.)
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
collected on adjacent LLDP devices—as well as the local data the
switch is transmitting to adjacent LLDP devices (page 14-35).
Using an SNMP application that is designed to query the Neighbors
■
MIB for LLDP data to use in device discovery and topology mapping.
(In the 3400cl and 6400cl switches only, this includes CDP data the
switch has read and mapped to the LLDP counterpart.)
