Cisco WLC polling issue

Due to a bug in Cisco WLC (Cisco won’t fix) LibreNMS suddenly stopped polling our WLC.

Error message:
Caching OIDs: entPhysicalDescrSNMP[’/usr/bin/snmpbulkwalk’ ‘-v2c’ ‘-c’ ‘COMMUNITY’ ‘-OQUs’ ‘-m’ ‘ENTITY-MIB’ ‘-M’ ‘/home/librenms/mibs:/home/librenms/mibs/cisco’ ‘udp:HOSTNAME:161’ ‘entPhysicalDescr’]
Exitcode: 1
Error: OID not increasing: entPhysicalDescr.1008

= entPhysicalDescr.936

The workaround is to use -Cc in snmpwalk, can this option be set for WLC devices only in LibreNMS?

Been seeing this popping up a few poor devices. I think I have an idea for how to cleanly work around it now, but will take some time to implement.

Ok, looking forward to it, thanks!

That was fast, thank you very much, seems to be working again after commit: Fix Cisco WLC AP cleanup (#13615)
