cmiTest

Test the quad connections between two ASIC connections.
Synopsis
cmiTest [passCount]
Availability
admin
Description
Use this command to verify that the multiplexed 4-bit Control Message Interface (CMI) point to
point connection between four quads located between two ASICs is functioning properly. This
command is also used to verify that a message with a bad checksum sets the error and interrupt
status bits of the destination quad and that a message with a good checksum does not set an error or
interrupt bit in any ASIC.
Note:
The Test method is displayed below. Complete the following for each source quad X and each
destination quad Y in the switch. Do not complete this test if quad X = quad Y.
1. Generate the CMI data D.
2. Send data from source quad X to destination quad Y.
3. Check destination quad Y for the following:
- the capture flag is set.
- the data is received as expected (D).
- if a good checksum test, the CMI error bit and the EMI error interrupt status bit are not set.
- if a bad checksum test, the CMI error bit and the CMI error interrupt status bit are set.
4. Check that all quads (other than Y) do not have:
- the capture flag set.
- the CMI error bit set.
- the CMI error interrupt status bit set.
Operands This command has the following operand:
passCount
Example
To run a quad to quad connection test between two ASICs:
1-30
This command may not be executed on an enabled switch. You must first disable the switch
using the switchDisable command.
Specify the number of times to execute this test. The default value is 1. This
operand is optional.
