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?
Import the correct vendor-specific MIB file for the router into the network management system.
Manually create a set of generic definitions in the management system to temporarily replace the missing MIB.
Initiate a device reboot on the router to trigger automatic MIB discovery by the management system.
Adjust the management system's threshold settings to bypass the need for device-specific definitions.
Change the protocol used by the management system to communicate with the router to a simpler one that requires no MIBs.
