SNMP MIB Import for cisco devices

Hello there,

i have a demo version installed to test the OPManager and now i want to import snmp mibs for cisco devices because the graph for cpu utilisation and backplane utilisation aren�t visible. There are about six different device types in our network here. I have now downloaded some mibs from the cisco web site which look like this: OLD-CISCO-MEMORY-MIB.my . When i try to load these mibs using the mib browser i get the following erro messager: Error parsing MIB: I have read that i have to compile those .my-files but i don�t know how i can do this? I�m new to snmp and mibs. If some one could explain this to me for newcomers how i can import cisco mibs this would be great.

Thanks a lot.

BR.
Chris
