Troubleshooting active/standby MPU
switchover
This section provides troubleshooting information for common active/standby MPU switchover
problems.

Exceptional standby MPU reboot

Symptom

The standby MPU also reboots when the reboot command is used to reboot the active MPU.

Solution

To resolve the problem:
1. After the original active MPU starts up, use FTP or TFTP to transfer the up-to-date log files in
the logfile directory on the MPU to the file server.
2. Search the log file for the reboot log message, for example, Command is reboot slot 0.
3. Search the log file for the most recent system restart log message, for example,
SYSLOG_RESTART: System restarted.
