backport

Note: Enter commands in lowercase only; mixed case is for readability.

-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

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:

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
