To test for backend ASIC pair links:
Diagnostics
When the command detects failure(s), the test can report one or more of the following error messages:

PORT_DIED
PORT_STOPPED
XMIT

-lb_mode 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
-fr_type type Specifies the frame type to send. The default value is 1.
Type Description
0Single 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.
