As mentioned  before in this list: there is not much use in querying the
cpu figures for Cisco switches because the cpu is not involved in the
handling of the traffic.

By getting the right MIB file(s).

Sometimes you need more than one MIB file because of the fact that the
mib file that contains the oid you want to see in text is not directly
hooked to the main oid structure. If you use an text editor to view the
MIB file you will see an "Import.." line followed by: "From.. xxx". In
this case xxx is the name of the "parent" MIB file you have to find. (If
you use getif, it will show in its logfile a warning like: "Module xxx
not found")
