I think the problem is in Prime 2.2.
On ASA 5545 I can see logging of this problem, but It may affect WS-C6506-E and WS-C4507R-E but in debug snmp header and packet I just can see no error and it all looks good still same error in Prime : SNMP Connectivity Failed. See picture1
debug in switches with debug snmp packets:
037412: Apr 29 15:09:08.312 CEDT: SNMP: Packet sent via UDP to 10.100.7.92

......
At the logging of ASA I did see error message: See picture2
%ASA-3-212005: incoming SNMP request (number bytes) on interface
interface_name exceeds data buffer size, discarding this SNMP request.
The length of the incoming SNMP request that is destined for the ASA exceeds the size of the internal data buffer (512 bytes) used for storing the request during internal processing. The ASA is unable to process this request. The SNMP traffic passing through the ASA on any interface is not affected.
But when I look at what I have collected of the ASA: IOS image config (upto date) etc it looks fine but still error on Inventory. I do remember I had seen completed just when I had installed Prime just few weeks ago.
Just very strange why this is happening.
