E-Series TeraScale Debugging and Diagnostics | 1201RPM-SFM bring downIf a full set of SFMs are online during the runtime loopback test and a RPM-SFM runtime loopback testfailure occurs, an automatic SFM walk is launched in an attempt to determine if the failure is due to afaulty 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-SFMruntime loopback test, use the following CONFIGURATION mode command.Manual loopback testThis manual dataplane loopback test is a supplemental test to the automatic runtime loopback test and canbe initiated regardless if the runtime loopback test is enabled or disabled. Use this test to verify that thedataplane 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.Task Command ModeDisable the automatic SFM walk that islaunched after an RPM-SFM runtimeloopback test failure.To re-enable the automatic SFM walk, usethe no dataplane-diag disablesfm-walk command.dataplane-diag disable sfm-walk CONFIGURATIONNote: Disabling the sfm-walk command prevents the sfm-bringdown command from taking effect.Task Command ModeDisable the automatic bring downof the single faulty SFM identifiedby the SFM walk during theRPM-SFM runtime loopback test.To re-enable the automatic bringdown of an SFM, use the nodataplane-diag disablesfm-bringdown command.dataplane-diag disable sfm-bringdown CONFIGURATION
