Base System Ethernet Controller Tests
The following entries explain the commands, parameters, and
error messages for each individual Ethernet controller test.
Collision Test
The collision test checks Ethernet collision detect circuitry by
forcing a collision on transmission. To run the collision test,
type
t 3/ni/cllsn
and press Return.
Collision test error messages
Collision test error messages have the form
?TFL: 3/ni/cllsn (
code
:
description
)
?TFL: 3/ni/cllsn indicates that the collision test reported a
problem.
code represents a number that identifies which portion of
the test failed.
description represents additional information that describes
the failure.
Table D-18 lists error codes and descriptions used in collision
test error messages.
