Fabric OS 5.0.0 command reference guide 107
Verifies the control message interface (CMI) bus between ASICs.
Synopsis
cmitest [--slot slotnumber][-passcnt count][-txports itemlist][-rxports
itemlist][-skip mask]
Availability
admin
Description
Use this command to test:
• Multiplexed 4-bit CMI point-to-point connection between two ASICs.
• Message sent with a bad checksum sets the error and interrupt bits of the destination ASIC.
• Message sent with a good checksum does not set any error or interrupt bit in any ASIC pair.
The CMI is used to send transmission requests or completion messages between the ASIC transmitter and
receiver.
Options
This command has the following options:
Examples
To run a CMI test between two ASIC pairs:
cmiTest
--slot slotnumber Specifies the slot number to test. The default is set to 0 and designed
to operate on fixed-port-count products.
-passcnt count Specifies the number of test passes to run. By default, the test runs one
time.
-txports itemlist Specifies a list of ports to transmit data. By default, all the ports in the
specified slot (--slot) are used. Refer to itemList help pages for
further details.
-rxports itemlist Specifies a list of ports to receive data. By default, all the ports in the
specified slot (--slot) are used. Refer to itemList for more
information.
-skip mask Specifies tests to skip using a bit map as follows:
1 CMI data test (ignore checksum)
2CMI checksum test
3 Enable all tests
