cmiTest
Verifies the control message interface (CMI) bus between ASICs.
Synopsis cmitest [--slot slotnumber][-passcnt count][-txports itemlist][-rxports itemlist][-skip mask]
Description Use this command to test:
The multiplexed 4-bit CMI point-to-point connection between two ASICs.
The message sent with a bad checksum sets the error and interrupt bits of the destination ASIC.
The 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.
This command is supported only on Brocade 3250, 3850, 3900,and 24000 platforms.
The execution of this command is subject to Admin Domain restrictions that may be in place.
Operands This command has the following operands:
--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)
• 2 CMI checksum test
• 3 Enable all tests
Examples To run a CMI test between two ASIC pairs:
switch:admin> cmitest -txports 7/0-7/7 -rxports 7/8-7/15
