Depending on your need to add MIBs for managing nodes, you must compile the MIBs.
To delete a particular MIB from Novell ZENworks Server Management, remove the appropriate MIB text file from the MIB Server Pool and rerun the MIB Compiler. If the MIB you delete contains traps, you must remove the alarm definitions before you rerun the MIB Compiler.
When you add MIBs, you choose to integrate or exclude the trap information while compiling MIBs. If you disallow trap integration with the MIBs, only the MIB information is stored in the database on successful compilation of the MIBs.
For more information about how to add or remove MIBs, refer to Compiling MIBs for SNMP-Manageable Nodes.
