    Capturing and Writing Core Dumps

    You can capture and write a core dump to a file for an active or a standby SRP module or the line modules. You can store the file on the file system or on a network host. The SRP core dump files are stored on the respective SRP flash memory. The line module core dump files are stored on the active SRP flash memory at the instance of the core dump event. The core dump files are not synchronized between the active and the standby SRP module. You can use the resulting information to help diagnose a problem or to verify whether the core settings are correct (primarily for the network settings).

    To reboot the active SRP module, the standby SRP module, or the module in a specified slot, and write the core dump to a file:

    • Issue the write core command in Privileged Exec mode. If you specify the force keyword, you are prompted for confirmation to reboot when the router is in a state that can lead to loss of configuration data or NVS corruption.

      Note: The force keyword enables you to specify a slot only if that slot is an SRP module slot.

      If you do not specify a reason, Write Core is the default reason recorded in the reboot history.

      • Prompt for confirmation to reboot:
        host1#write core force
      • Reboot the module in slot 7 and write a core memory file:
        host1#write core slot 7
