Hello all. 

This is my second posting to the mailing list. Im afraid i will probably annoy most of you all but i have no where else to turn to:)

I have a Cisco 5509. I want to monitor ports on it. I have done an ifindex on the router and have the ifnumbers. I went to Somix, got the template they provide. It simply will not work (see below for error). I had no problem what so ever monitoring some Cisco 1924 switches with somix's templates. What is different about the 5509? 

I am quite new to SNMP i must admit and it is by far the complicated thing i have ever come across. (or maybe i am as stupid as i look ;) )

Also... I can do an snmpwalk fine.. i have absolutely no idea how to tell what info from a walk is usefull to me for to monitor ports....

Here is the error i am getting:

SNMP Error:
