I have a trial of opSLA and have set it up but I am now trying to set up a probe and responder for the first time, I have an SNMP community RW string set up on two test devices. when I try to set up the probe and the responder I get the Message "Error snmpset attributes for probe jitter" and the status "error delete", I have set debug for snmp-server and the server does seem to connect.

There doesn't seem to be any check list to check you have the router config set up correctly, I was advised that giving snmp RW access would allow NMIS to create the probe and responder.

      Hello Andrew,

      Configuring opSLA should be straight forward, however not all Cisco routers support the IP SLA standard or respond the way they should. I suggest you double check your installation and configuration of opSLA first: Home

      If this looks good, then please post back the manufacturer, model and OS (with version) of the router you're trying to create a probe on and we'll see what we can see.

        A useful resource for checking IOS versions compatible with this MIB is here:


        And if you would like to test the SNMP SET function then one can use the folliwing commands on the server

        #set these variables to suit your environment

        # your Read Write community string

        # the IP of the router for the SLA poller
        # The IP that the poller will test to in HEX
        # A random number for table entry

        #The SNMP Set request as a single command across multiple lines

        snmpset -m ALL -M /usr/local/nmis8/mibs/traps -v 2c -c $community $host \
         rttMonCtrlAdminStatus.$entry i 4 \
         rttMonCtrlAdminRttType.$entry i 1 \
         rttMonEchoAdminProtocol.$entry i 2 \
         rttMonEchoAdminTargetAddress.$entry x $node \
         rttMonCtrlAdminFrequency.$entry i 30 \
         rttMonCtrlAdminTimeout.$entry i 2000 \
         rttMonEchoAdminTOS.$entry i 64 \
         rttMonCtrlAdminVerifyData.$entry i 2 \
         rttMonHistoryAdminNumBuckets.$entry i 30 \
         rttMonHistoryAdminNumLives.$entry i 1 \
         rttMonHistoryAdminFilter.$entry i 2 \
         rttMonScheduleAdminRttStartTime.$entry t 1 \
         rttMonScheduleAdminRttLife.$entry i 2147483647



        You will see if there are any errors trying to set those variables.


        You might also wish to run a debug of SNMP on the target router to see what is happening there

        "debug snmp packet"
