ASA is dropping snmp traffic from Ciscoworks LMS saying the request is too large (see msg below). I have adjusted this size in other snmp polling engines in the past. How do I correct this in LMS? thanks, Graeme
3 Jun 27 2008 14:58:56 212005 incoming SNMP request (552 bytes) from IP address 10.x.y.z. Port 1355 Interface "MGMT" exceeds data buffer size, discarding this SNMP request.
There is no way to adjust the polling packet size in LMS. However, I have never seen this error reported from any other customer, and this packet size does seem rather large. What packet is generating this message?
Note that the traffic is NAT'd via an ISA firewall. I have confirmed in the ISA logs that the LMS host is the only IP address snmp polling the ASA.
Have captured the offending request off the ASA. The request contains polling for IF-MIB, cisco memory and sysuptime. It is consistently 20mins apart with 1 retry and timeout of 3sec. (pcap attached see pkt#4-5)
I thought it might be HUM but the HUM poller for the ASA is set to 5 mins
