www.dell.com | support.dell.com 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. (Figure 61-6) Figure 61-6. reset sfm command example FTOS#reset sfm 0 SFM0 is active.

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 both EtherScale and 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. 1204 | E-Series TeraScale Debugging and Diagnostics
