A critical alert from your network management system indicates a failure in collecting performance metrics from a newly installed router. Investigation reveals that the management system cannot interpret the incoming data due to missing definitions. How should you rectify this issue to ensure complete data collection?
Adjust the management system's threshold settings to bypass the need for device-specific definitions.
Manually create a set of generic definitions in the management system to temporarily replace the missing MIB.
Change the protocol used by the management system to communicate with the router to a simpler one that requires no MIBs.
Import the correct vendor-specific MIB file for the router into the network management system.
Initiate a device reboot on the router to trigger automatic MIB discovery by the management system.
