LLDP cisco


I have lot of cisco switch.
and lot of ip phone.
I would like retrieve end device via lldp for network map.

I would like use LLDP-EXT-MED-MIB in discovery-protocols module for retrieve end devices in Cisco switch.
When i do "php discovery.php -h myswitch -d -m discovery-protocols "


LLDP-MIB: SNMP[/usr/bin/snmpbulkwalk -v2c -c COMMUNITY -OQUs -m LLDP-MIB -M /opt/librenms/mibs:/opt/librenms/mibs/cisco udp:HOSTNAME:161 lldpRemoteSystemsData]

But, script don’t retrieve lldp informations like LLDP-EXT-MED-MIB.


Here is the doc on auto discovery https://docs.librenms.org/Extensions/Auto-Discovery/
that should discover your devices with lldp. If you have everything configured properly.

Also network map: https://docs.librenms.org/Extensions/Network-Map/

My configuration seems Ok.
CDP is Ok.

But the script discovery-protocols dont’t retrieve LLDP information of end device.
Because cisco switch don’t sent information for OID snmp in the script.
It seems that not possible with the OID in the script.


But, it’s possible with this MIB LLDP-EXT-MED-MIB.

see : lldpExtensions.4795. > 6


Im not sure what you are trying to do here?

Moved to feature requests, you’re asking for additional support to LLDP discovery.
