Running Hardware Diagnostics
The
test
command initiates one or more test routines on a switching module that you
specify. You can also optionally test all switching modules in one test session. Test status,
instructions, and a summary of results are provided as output. Start a diagnostic test session
using the following command syntax:
test <slot_number> [<repeat_count> [<test_name>]]
where
<slot_number>
Indicates the slot number in the Omni Switch/Router for the module on
which you want to run tests. If you enter
all
for this parameter, then all
switching modules in the chassis will be tested. This parameter is required;
if you do not enter a slot number then the test session will not start.
<repeat_count>
Indicates the number of times to run the specified tests on the module.
This value can be an integer between 0 and 999. A value of zero (0)
repeats the test infinitely. The default value is 1. This default will be
assumed if you do not enter a
repeat_count
.
<test_name>
Indicates the test to be performed on the module. You can indicate the test
name or
all
to run all tests. You can enter only one test name or
all
. The
default is
all
. This default will be assumed if you do not enter a
test_name
.
♦
Note
♦
A combination of
repeat_count
set to
0
and
test_name
set to
all
allows the user to run either the port test
infinitely or all off-board tests infinitely. If the user
chooses to run the port test when prompted, all the
static tests (memory and control/status register tests)
are run once, followed by an infinite run of the port
test. See
Sample Command Lines on page 36-9 for
more information.
Descriptions of each test follows:
alpreg
Tests the Alpine registers. Test the Alpine control logic, registers, and
data/address lines.
csr
Tests the command/status registers. Includes testing management bus
buffers, management bus read/write control logic, reset and
LED
memory,
ID EEPROM
, and reset circuitry.
gigareg
Tests the Giga-Chip registers. Test the Giga-Chip control logic, registers,
and data/address lines.
hrexmem
Tests the
HRE-X
’s local memory. Includes testing the
HRE-X
read/write
functions, data/address, and the memory.
hrexport
Tests the
HRE-X
’s functions. Packets are generated by the
MPX
, sent out
to the port, and claimed by the
HRE-X
. The
HRE-X
will insert additional
routing information to the claimed packet and place it back on
MVBUS
to
be claimed and verified by the
MPX
. This test can be bypassed. See
Running Diagnostics on an Entire Chassis on page 36-20.
ilb
Performs a port test using the internal loopback at the
PHY
or framer
interface. Packets are generated by the
MPX
and sent out to the port and
returned through an internal loopback within the
PHY
or framer. The
MPX
verifies the packets on a bit by bit basis.
