Use removemib to delete vendor SNMP MIB files from the MIB library in NetMRI. The removemib command automatically points to a location in the system, that contains all MIBs installed by admins into NetMRI. (For a list of installed MIBs, you can go to the Settings icon > Setup > MIB Management.) Removemib removemib is limited to MIBs that are installed by admins of the system; MIBs that are bundled with NetMRI cannot be deleted using this command. You should also know the file name for the MIB before deleting it. Files of this type are placed into the /var/local/netmri/dsb/mibmanager/source directory. If no MIB files are located in this folder, you will not be able to remove remov any other MIB files.
