This has happened to me on one of the switches I upgraded, but on another one I did, same configuration, it worked...
The error in the logs I get on the one that's not working is:
2147483613 | 2012-Jan-19 17:33:24 | Warning | %SNMP-W-SNMPAUTHFAIL: Access attempted by unauthorized NMS, aggregated (3) |
2147483614 | 2012-Jan-19 17:31:10 | Warning | %SNMP-W-SNMPAUTHFAIL: Access attempted by unauthorized NMS |
No idea why.
Tried changing the SNMP management station to "All" and this still does not help.

Hi,
I was curious about your findings, so i thought I would just put a SNMP server on a spare PC to check your findings.
I am using version 1.1.2.0 on my SG300-10P (order p/n SRW2008P-K9-NA) and just configured SNMP on the switch.
I must admit that the unit was factory reset yesterday, after I enabled Layer 3 mode on the switch.
I did see the following warning on my switch log, before I configured the correct community name on my SNMP manager.;
13-Nov-2011 00:08:53 :%SNMP-W-SNMPAUTHFAIL: Access attempted by unauthorized NMS, aggregated (4)
This or similar SG300-10P log message didn't return after I configured the correct SNMP community name on the SNMP manager. .
But as you can see if you click on my screen capture below.
I am wondering if it is the community name that may have somehow through some firmware upgrade not carried the correct community name.
Could be interesting to see what happening is you delete SNMP Community from the switch and add a SNMP community again.
I hate suggesting try a factory reset, but it could be interesting as a last resort to try it.
Sorry it's anly a guess on my part, but on my switch and SNMP Manager, SNMP seems to be "doing its thing" without new switch log entries.
If that fails, why not give the good folk at the Small Business Support Center (SBSC) a call.
