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. The PCDFO polling feature is enabled by default. 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 the following. Message 5 DFO Error Message %RPM1-P:CP %CHMGR-2-SFM_PCDFO: PCDFO error detected for SFM4 Figure 63-3 illustrates the SFM architecture.
