Use this Knowledge Script to remove one or more MIB files from an SNMP proxy agent computer. The specified files are deleted from the installation folder, which by default is installationfolder\AppManager\bin\AMSnmpMIBs.
Run this script when no other SNMP Knowledge Scripts are active on the target AppManager SNMP Toolkit installation because reloading the MIB tree can only be done when no SNMP sessions are active. If the RemoveMIBs Knowledge Script is unable to reload the MIB tree because of active SNMP sessions, the script can raise an appropriate event.
This script raises an event if the specified MIB files cannot be deleted, or an ASN.1 compilation error occurs while reloading the MIB tree.
SNMP MIBs tend to be hierarchical. That is, one MIB is often dependent on another, from which it imports more generic data definitions. Therefore, delete a MIB only if it has no other dependent MIBs installed.

Event severity when reload MIB parser warnings received |
Set the severity level, from 1 to 40, to indicate the importance of an event in which MIB reload warnings are received. The default is 15. |
