www.dell.com | support.dell.com Like the line card to SFM results, line card S3 loopback tests results are displayed when you use the show trace linecard command. Messages appear indicating whether the test was successful or not (Message 4).

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. Task Command Execute a manual dataplane loopback test: • all-loopback - dataplane loopback test on all line cards This test can be run when the switch fabric is in either an operational or a non-operational state. diag sfm [all-loopback] Mode EXEC Privilege If the line card-SFM loopback test detects an SFM failure, an attempt is made to isolate a single faulty SFM by automatically walking the SFMs. For this failure case, error messages similar to the runtime loopback test error are generated. 1108 | E-Series ExaScale Debugging and Diagnostics
