Problems with Switch Port Mapper and SNMP v3?

Hi!

I'm trying to implement SNMP v3 on my Cisco switches, but I have stumbled over something strange:
I'm not sure if this is a Cisco problem or a Switch Port Mapper (SPM) problem, but either way I need help

Earlier I have used a simple community string in my switches to use with SPM and things have worked fine (mostly).

But when I setup SNMP v3 like this:
snmp-server group SNMPA v3 auth write v1default
snmp-server user username SNMPA v3 auth sha password

and then try to use that with SPM, it lists only a few of the ports on the switch every time.
It seems that it lists only ports in trunk mode.
When I switch back to a community string it works fine again.

What can cause this?
As you can see I use the Cisco default v1default view. Are there some limitations to that maybe? Solarwinds Orion don't seem to have problems with it at least.

Any ideas?

Thanks.

Yes, I have the same problem! Where is the SW's support team? My cases about IP Network Browser and Real-Time Interface Monitor (## 14109 & 18079) are unanswered also!

I think this is a SPM problem. I installed version 9.2 today. Something's wrong too. When I try to use SNMPv3 with SPM, it lists ALL of the ports on the switch, BUT with ONLY ONE ROW for the non-trunked ports WITHOUT Device MACs values in the row. With SNMPv1-community SPM works fine (although I don't make sure of even it now ...)

Can anyone from SW confirm this?

Thanks.

Development is looking into this issue. Thank you for your patience. At this point we're not sure if the issue is only with SNMP v3 logins or what. Can you help by checking if you can reproduce this issue with SNMP v3 login on a 9.1 Toolset install?

Thanks,

My version is 9.2 and the issue is reproduced.
