Brocade VDX unable to retrieve LLDP neighbours (DEF included)
« on: July 13, 2021, 10:14:35 am »
Concerns the Brocade VDX BR-VDX6740 with Extreme Networks NOS. LLDP is running on the devices and a show lldp neigbours works fine. Via snmpwalk i can see all information. Management IP's for neigbbours are also visible with snmpwalk (oid 1.0.8802.1.1.2.1.4.2.1.3):

I tried first via LLDP but got nedi verbose output i should try LLDPX. Changed this in the DEF file and i can see some progress but no links visible in the GUI. Eventually libsnmp.pm gives an error. Not sure why. Does anyone know how to troubleshoot/fix this?

Verbose output for LLDP:

Try LLDPXN (to match against IFnames instead IFdescriptions) and see, if it changes anything...

Might be that my DEF file is not 100%.
