Information
If the RPM-SFM or line card-SFM loopback test detects an SFM failure, an attempt is made to isolate
a single faulty SFM by automatically walking the SFMs. For this failure case, error messages similar to
the runtime loopback test error are generated.
If the test passes when the switch fabric is down and there are at least (max-1) SFMs in the chassis,
then the system will bring the switch fabric back up automatically. Like the runtime loopback test, the
manual loopback test failure will not bring the switch fabric down.
