Fabric OS Command Reference Manual 45
53-1000436-01
backport
2
5 Internal (parallel) loopback
-fr_type type Specifies the frame type to send. The default value is 1.
Type Description
0 Single frame
1 spinfab frames
2 spinfab 1K frames
-extonly mode 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.
Examples 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

PORT_DIED
PORT_STOPPED
