I’m trying to setup Observium to poll all of our switches, and so far I just love it. Great job guys! I hope to convince the management to subscribe soon, but for now we’ll have to do with the community version.

Let me try to explain my issue. I am polling a dual stack of Nortel Baystack 5510-24T switches using snmp v2c. All ports of unit 1 and ports 1 – 6 of unit 2 look fine. The graphics (bits/sec) for port 7 to 24 of unit 2 are strange though. Port 7 is not used, no device is connected to it at all. The average traffic according to the graphs is around 30Gbit/s. All other ports after port 7 show the exact same numbers. So first I tried to reset all port statistics on the switch. The graphs showed 0 bits/s for a few minutes, but then after let’s say 30 minutes it shows a current bandwidth of 8Gbit/s. I tried deleting the device from Observium and added it again, but it seems that all counters are still there. When I look at the port using telnet, all counters are 0. I know that this switch is not in the supported devices list, but as far as I know the default snmp pollings should provide correct numbers for bandwidth statistics, no?

Any help is greatly appreciated!
