Rpm-Sfm Bring Down; Manual Loopback Test - Dell Force10 C150 Configuration Manual

Task
Disable the automatic SFM walk that is
launched after an RPM-SFM runtime
loopback test failure.
To re-enable the automatic SFM walk, use
the no dataplane-diag disable
sfm-walk command.
Note: Disabling the sfm-walk command prevents the sfm-bringdown command from taking effect.

RPM-SFM bring down

If a full set of SFMs are online during the runtime loopback test and a 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 SFM is identified and disabled (bringdown) by default.
To disable the automatic bring-down of an SFM that is identified by the SFM walk during the RPM-SFM
runtime loopback test, use the following CONFIGURATION mode command.
Task
Disable the automatic bring down
of the single faulty SFM identified
by the SFM walk during the
RPM-SFM runtime loopback test.
To re-enable the automatic bring
down of an SFM, use the no
dataplane-diag disable
sfm-bringdown command.

Manual loopback test

This manual dataplane loopback test is a supplemental test to the automatic runtime loopback test and can
be initiated regardless if the runtime loopback test is enabled or disabled. Use this test to verify that the
dataplane is actually functional even when a switch fabric status is down but there are at least (max-1)
SFMs in active or diag failure state.
Command
dataplane-diag disable sfm-walk
