Morning
Cisco Prime LMS 4.2.3 is sending SNMP request too big for asa interface buffer.
LMS is running on Windows server
incoming SNMP request (528 bytes) from IP address x.x.x.x Port 50592 Interface "inside" exceeds data buffer size, discarding this SNMP request.
212005: incoming SNMP request (%d bytes) from %s exceeds data buffer size, discarding this SNMP request.
It is very much like this error
Error Message %PIX-3-212005: incoming SNMP request (number bytes) on interface interface_name exceeds data buffer size, discarding this SNMP request.
Explanation This is an SNMP message. This message reports that the length of the incoming SNMP request, destined for the firewall, exceeds the size of the internal data buffer (512 bytes) used for storing the request during internal processing; therefore, the firewall is unable to process this request. This does not affect the SNMP traffic passing through the firewall via any interface.
Recommended Action Have the SNMP management station resend the request with a shorter length, for example, instead of querying multiple MIB variables in one request, try querying only one MIB variable in a request. This may involve modifying the configuration of the SNMP manager software.
how do I change the SNMP request size in LMS?
I can only find the following that might be an option
any thoughts on the matter would be appreciated
just using default settings with snmpv3

We have the same issue with Firewalls that are running 9.1.2 or below code. We recently upgraded 2 of our firewalls to 9.2.3 then pushed SNMPv3 on all including these firewalls from Prime 2.2 and only these 2 upgraded firewalls are synced up with Prime without any issues. So this means that this issue has been fixed in version 9.2.3
Thanks,
