Hi Bob,

Looks like the numbers are indeed fluctuating SNMP-wise - can't see how it's a bug on our side, the number is consistent with the real speed of a single interface as well, so I'm afraid you'll have to check with HP.

Looks like it's reporting "sometimes" that it's down to 10G, and the next poll 5min later restores it to 40G.

We recently installed Observium and we’re receiving messages from the majority of our C7000 Virtual connects in the event log that look like this:

These VC’s have a 4 port LACP group to the core switch. I see nothing in the system log on either side that would indicate the interface speed is actually changing (link downs, errors) or other SNMP errors, so I’m inclined to think these message can be ignored. Any thoughts? If it’s a bug in the HP SNMP implementation on the VC’s I can submit a ticket. Otherwise I’d like to find a way to suppress them if I can.
