Disable Rpm-Sfm Walk - Dell Force10 C150 Configuration Manual

• An SFM walk will not be able to identify multiple faulty SFMs, faulty linecards, or faulty RPM. In this
case, the following event is logged.
Message 2 SFM walk Event Log
%TSM-2-RPM_LOOPBACK_FAIL: RPM-SFM dataplane loopback test failed
%TSM-2-SFM_WALK_START: Automatic SFM walk-through started
%TSM-2-SFM_WALK_FAIL: Automatic SFM walk-through failed to identify single faulty SFM
• If a line card runtime loopback test fails, the system does not launch an SFM walk. A message is
logged indicating the failure.
Message 3 Loopback test failure
%TSM-2-RPM_LOOPBACK_FAIL: Linecard-SFM dataplane loopback test failed on linecard 6
The runtime dataplane loopback test is enabled by default. To disable this feature, use the following
command.
Task
Disable the runtime loopback test on the primary
RPM and line cards.
To re-enable, use the no dataplane-diag
disable loopback command
Note: Disabling the runtime loopback test prevents the sfm-walk command and sfm-bringdown
commands from taking effect.

Disable RPM-SFM walk

If a full set of SFMs are online during the runtime loopback test and an RPM-SFM runtime loopback test
failure occurs, an automatic SFM walk is launched in an attempt to determine if the failure is due to a
faulty SFM. If confirmed, the single faulty SFM is identified and disabled by default.
To disable the automatic SFM walk that is launched after an RPM-SFM runtime loopback test failure, use
the following command in CONFIGURATION mode.
