Dell Force10 E1200i FTOS Version 8.4.1.5 Configuration Guide for ExaScale - Page 1085

Reset the SFM When the SFM is taken offline due to an error condition, you can execute the reset sfm command and initiate a manual recovery. Task Reset a specific SFM module (power-off and then power-on). Command reset sfm slot-number Mode EXEC When an error is detected on an SFM module, this command is a manual recovery mechanism. Since this command can be used with live traffic running, the switch fabric will not go down if the switch fabric is in an UP state. When there is a full set of SFMs online in the chassis, resetting one SFM will reduce the total bandwidth supported by the chassis and may effect data flow. A warning message is issued at the command line and requires user confirmation to proceed. FTOS#reset sfm 0 SFM0 is active. Resetting it might temporarily impact data traffic. Proceed with reset [confirm yes/no]:yes Feb 16 00:39:30: %RPM1-P:CP %TSM-5-SFM_DISCOVERY: Found SFM 0 FTOS# This command does not permit resetting any SFM when the system has (max-1) SFM and switch fabric is up. FTOS#Force10#reset sfm 1 % Error: SFM1 is active. Resetting it will impact data traffic. FTOS# Note: Resetting an SFM in a power-off state is not permitted. Use the command power-on sfm to bring the SFM back to a power-on state. SFM channel monitoring In addition to monitoring the datapath, the SFM channels can be monitored using the Per-Channel Deskew FIFO Overflow (PCDFO) polling feature on all line cards and RPMs in TeraScale E1200, E600, and E300 chassis. Like the datapath loopback feature, the PCDFO polling feature is enabled by default. Note: This feature is not supported on the E600i chassis. The PCDFO polling feature monitors data received over the switch fabric. When a DFO error is detected, no automatic action is initiated by the system. The message issued is similar to: Message 4 PCDFO error message %RPM1-P:CP %CHMGR-2-SFM_PCDFO: PCDFO error detected for SFM4 E-Series TeraScale Debugging and Diagnostics | 1085
