Hi, I am trying to figure out Cisco's MIB files. They are names with an extension ".my", and they don't look like standard MIBS. I tried to upload one of them to Opmanager but I get an invalid MIB error.

Here is an example- I want to load MIBs for my 4402 Wireless Lan Controller, and this is their list of MIBs for it:

ftp://ftp-sj.cisco.com/pub/mibs/supportlists/wlc/wlc-supportlist.html

Are these regular MIBs that OpManager can import? Do I need to modify them?
Also here is a list of all their other MIBs:
