Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
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 13-36).
â– Using an SNMP application that is designed to query the Neighbors
MIB for LLDP data to use in device discovery and topology mapping.
(This includes CDP data the switch has read and mapped to the LLDP
counterpart.)
â– Using the walkmib command to display a listing of the LLDP MIB
objects
