Hi,
please make discovery debug for this device:
./discovery.php -d -h <device>

We have a Cisco C2960S running 12.2(55)SE3 that Observium insists has a whole bunch of VLANs that don’t actually exist on the switch.
The VLANs (No Graphs) screen, for example, shows:

…but VIDs 6, 10 and 91 don’t actually exist on this device:
UMTor1#show vlan id 6
VLAN id 6 not found in current VLAN database
UMTor1#show vlan id 10
VLAN id 10 not found in current VLAN database
UMTor1#show vlan id 91
VLAN id 91 not found in current VLAN database
I have manually re-run discovery, successfully.
Every bogus VID strictly follows a valid VID, i.e. 5 is valid, 6 is not. 9 is valid, 10 is not. 90 is valid, 91 is not. And so on.
Anyone else run into this?
Any ideas how to troubleshoot this?
Thanks,
-Adam
