E-Series Debugging and Diagnostics
•
show tech-support
In addition to these debug commands, FTOS supports diagnostics, monitoring, and fault isolation
commands to assist in gathering information.
•
Unless otherwise noted, these commands are available on TeraScale systems only.
•
The trace-log file captures failure information on most failure events.
•
The RPM-SFM runtime loopback test failure initiates an SFM walk. The system automatically
places each SFM (in sequential order) in an offline state, runs the loopback test, and then places
the SFM back in an active state. This continues until the system determines a working SFM
combination. If no working combination is found, the system restores to the pre-walking SFM
state
•
If the line card runtime loopback test fails, the system does not launch an SFM walk.
Note:
SFM walking assumes a chassis with the maximum number of SFMs in an active state.
Disable the runtime loopback test on the primary RPM and line cards.

To re-enable, use the no dataplane-diag disable loopback command.
