2 Note: Enter commands in lowercase only; mixed case is for readability. backport Examples -lb_mode mode -fr_type type -extonly mode Selects the loopback point for the test. By default, backport uses internal loopback. Mode Description 1 Port loopback (loopback plugs) 2 External (SERDES) loopback 5 Internal (parallel) loopback Specifies the frame type to send. The default value is 1. Type Description 0 Single frame 1 spinfab frames 2 spinfab 1K frames Specifies external-test-only mode. The default value is 0, which disables this mode. This command normally sends bursts of frames from each port under test to every other port in the list. With -extonly mode set to 1, the command sends only one burst of frames to each port from each ASIC pair-to-ASIC pair link. This tests all of the external connections with only K * N frames instead of the N^2 frames required in all-to-all mode. This mode is intended to be used in ESS/burn-in testing to optimize test time. backport tests only the external connections between each ASIC pair. txdPath is used to test the internal ASIC pair-to-ASIC pair paths. The values are: 0 Send frames from all ports to all other ports. 1 Send only one burst of frames to each link. To test for backend ASIC pair links: switch:admin> backport -ports 1/1-1/3 -nframes 840 One moment please ... backport running... backport: Completed 840 frames, status: passed. Diagnostics When the command detects failure(s), the test can report one or more of the following error messages: • ERR_STAT • ERR_STATS • INIT • PORT_DIED • PORT_STOPPED • XMIT Refer to the Fabric OS Message Reference for more information.
