I've got the problem, that i can not add new DELL attributes from 10892 MIB. I copied the original file from the "Installation and Server Management 5.1" CD into the mibs directory. When i choose 10892 from the drop down list i can select the mib and get all attributes shown. But when i select some attributes and klick on "Add Attributes" then I get the following Error:
Error ocurred while adding the specified MIB Objects. Please check if you have specified the correct SNMP Object Identifer and that the MIB is valid.
