Import MIB

hiii.. have anybody a short manual for my problem. I have tried many hours ago to import mib,
((CISCO-DYNAMIC-ARP-ISPECTION)), to Dude version beta 8,but still not work

can anybody show a step to import the MIB file.

These are the steps I used for the beta8 release to MIB info.

From the client console, right click on Mib Nodes and select open in separate window.
The Mib window will open. At the top. click on the File tab.
Click the red + sign.
Select your MIB file from its current location.
A dialog box will open showing the transfer of the MIB, click the Close window when all transfers finished checkbox (optional).
Once the transfer box reads 100%, it is uploaded to the MIB-base. Close the transfer dialog.
Your new MIB should be at the bottom of the list in the Mibs window. Close this window.
That should do it.
