'Invalid community specified in SNMP request' error

[SJCA53]

Hi all - on several controllers, we have the following settings in System Events:
SNMP enabled
Community (read only) Public
SNMP port 161

These are the default settings, and we've never messed with them. Our previous network manager turned on SNMP to assist with some monitoring. About a month ago, one of our controllers started repeatedly sendng us an 'Invalid community specified in SNMP request' error, and the only way to stop it was to turn off SNMP. Now I have a second controller doing the same thing. Any idea why that would suddenly start happening, when we haven't done anything that should be affecting this?

thx

Are you saying the IP Office is sending invalid/currupt traps to your SNMP console or that the SNMP console is not being able to read the IP Office on 161 correctly hence getting the error ?

If it is latter then I would suggest that you reenter the Community Name and Port number 161 and reboot your IP Office. You may also find that Sys-Monitor with SNMP options on my shed some light and assist with fault finding.

It is the latter; when I re-enter the settings and reboot, it keeps happening. Turning on SNMP options in Sysmon is a good idea; I will try that and see what turns up. Unfortunately, I can't deal with that immediately as I have other fires burning at the moment - I'm sure you all know how that is!
