Reducing SNMPGET requests
We have an issue where we see TONS of snmp get requests from our probe. This was originally causing our events log to show thousands of events for interface up/down's each day. Though they were not critical, it made our Ops team numb to any events in the log, so we stopped going through them at all. I know.. Not a best practice!!
So.. as I'm trying to tune out the alerts for up/down's on access ports (I think I finally figured that out!), I am seeing snmpget requests several times per minute. Polling on the device is set to 60 minutes now, and I have disabled status polling on each discovered interface. What else can I do to minimize these requests? As i'm monitoring the snmp packets out of the Cisco switch, it looks like the info is still for port statistics. An example of that being:
Sep 1 07:59:20: SNMP: Packet received via UDP from x.x.x.x on VlanXYZ
Sep 1 07:59:20: SNMP: Packet sent via UDP to x.x.x.x
Sep 1 07:59:20: SNMP: Get request, reqid 51006984, errstat 0, erridx 0
ifInOctets.10150 = NULL TYPE/VALUE
ifOutOctets.10150 = NULL TYPE/VALUE
ifInUcastPkts.10150 = NULL TYPE/VALUE
ifInNUcastPkts.10150 = NULL TYPE/VALUE
ifOutUcastPkts.10150 = NULL TYPE/VALUE
ifOutNUcastPkts.10150 = NULL TYPE/VALUE
ifInDiscards.10150 = NULL TYPE/VALUE
ifInErrors.10150 = NULL TYPE/VALUE
ifInUnknownProtos.10150 = NULL TYPE/VALUE
ifOutDiscards.10150 = NULL TYPE/VALUE
ifOutErrors.10150 = NULL TYPE/VALUE
Sep 1 07:59:20: SNMP: Response, reqid 51006984, errstat 0, erridx 0
ifInOctets.10150 = 0
ifOutOctets.10150 = 0
ifInUcastPkts.10150 = 0

ifOutUcastPkts.10150 = 0
ifOutNUcastPkts.10150 = NO_SUCH_INSTANCE_EXCEPTION

Any thoughts on this would greatly be appreciated!
