User response
Check the status of the CTCM device, for example, with ifconfig. Check if
the connection to the remote device still works. If the CTCM device is not
operational, set it offline and back online. If this does not resolve the
problem, perform a manual recovery. See "Device Drivers, Features, and
Commands" for details about how to recover a CTCM device. If this problem
persists, gather Linux debug data, collect the hardware logs, and report the
problem to your support organization.
