www.dell.com | support.dell.com diag sfm ex Execute a manual dataplane loopback test. Syntax diag sfm all-loopback Parameters all-loopback (OPTIONAL) Enter the keyword all-loopback to execute a dataplane loopback test from the RPMs and all line cards. Defaults No default behavior or value Command Modes EXEC Command History Version 8.1.1.2 Version 8.1.1.0 Introduced on E-Series ExaScale E600i Introduced on E-Series ExaScale E1200i Usage Information If the RPM-SFM or 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. If the test passes when the switch fabric is down and there are at least (max-1) SFMs in the chassis, then the system will bring the switch fabric back up automatically. Like the runtime loopback test, the manual loopback test failure will not bring the switch fabric down. Note: Line card-SFM loopback test failure, during the manual test, will trigger an SFM walk. Related Commands reset sfm Reset the SFM and bring it back online. ip control-plane egress-filter-traffic ex Apply Layer 3 egress ACLs to the CPU generated traffic. Syntax ip control-plane egress-filter-traffic To disable, use the no ip control-plane egress-filter-traffic command. Defaults Disabled 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 Usage Information CPU ACLs are useful for troubleshooting packet flow that has bypassed the hardware-based distributed forwarding path and is traveling directly to the RPM CPU. This command is useful in debugging the CPU originated control traffic. You can use the egress ACL with count option to verify if the control traffic sent by the CPU made it to the line card egress or not. 1540 | E-Series ExaScale Debugging and Diagnostics
