www.dell.com | support.dell.com In addition to these debug commands, FTOS supports diagnostics, monitoring, and fault isolation commands to assist in gathering information. Important Points to Remember • Unless otherwise noted, these commands are available on TeraScale systems only. • The trace-log file captures failure information on most failure events. • The RPM-SFM runtime loopback test failure initiates an SFM walk. The system automatically places each SFM (in sequential order) in an offline state, runs the loopback test, and then places the SFM back in an active state. This continues until the system determines a working SFM combination. If no working combination is found, the system restores to the pre-walking SFM state • If the line card runtime loopback test fails, the system does not launch an SFM walk. Note: SFM walking assumes a chassis with the maximum number of SFMs in an active state. dataplane-diag disable loopback ex Disable the runtime loopback test on the primary RPM and line cards. Syntax dataplane-diag disable loopback To re-enable, use the no dataplane-diag disable loopback command. Defaults Enabled Command Modes CONFIGURATION Command History Version 8.1.1.2 Version 8.1.1.0 Introduced on E-Series ExaScale E600i Introduced on E-Series ExaScale E1200i Related Commands show diag sfm Display the loopback test results Usage Information The runtime dataplane loopback test, by default, runs in the background. Every 10 seconds, the primary RPM and each line card sends packets through the SFMs and back again (loopback) to monitor the overall health status of the dataplane at a system level. This command disables that automatic runtime loopback test. Execute the show diag sfm command to view the diagnostics results. Note: Only the Primary RPM can perform runtime dataplane loopback test. 1538 | E-Series ExaScale Debugging and Diagnostics
