eem event snmp oid

[a-macaringue]

Good day

Can someone please explain me what the following line mean:

event snmp oid 1.3.6.1.4.1.9.9.42.1.2.9.1.6.2 get-type exact entry-op eq entry-

val "2" exit-op eq exit-val "1" poll-interval 5

If possible, please refer to an Cisco article for further searches.

Thank you

Antonio

It polls that oid every 5 seconds and triggers off the value in that oid if the value is equal to 2 and exits if the value is equal to 1.

Thank you for your answer and the link.

This policy will monitor the rttMonCtrlOperTimeoutOccurred value for IP SLA collector number 2.  If the value is equal to 2 (meaning a timeout did not occur), then the policy actions will execute.  They will not execute again until the value of rttMonCtrlOperTimeoutOccurred becomes 1 (meaning a timeout occurred) then becomes 2 again.

Do you see any inconsistency on this configuration?

A five second polling interval is very aggressive.  I typically recommend no lower than 10.  Is there any reason why you're not using Enhanced Object Tracking for this?  It would greatly simplify the applets, and make your reactions much quicker.
