Someone is trying to use snmp on your 6500 , if it doesn't tell you in the logs what address then you might have to use a sniffer . If it tells you then track down the address and ask the the user why his device is attempting an snmp query on that device.

Hi Thanks for the reply the host Ip address showing by the logs is one of my application server. kindly suggest the solution that how can i eradicate this issue

look in the server whether i genuinly uses the SNMP, if not stop any SNMP service on that server
