d.
Reading the error register clears the CMEM interrupt bit, preparing for the next offset to test.
Chip Number Error Subtest
The forced bad chip number error subtest verifies that the bad buffer number in the data packet can be
detected and its error flag and interrupt bits set.
The test method is as follows:
1. Clear the error and interrupt bits of all ASICs.
2. Set up the hardware so that transmission of data includes a bad buffer.
3. For each of the 11 possible offsets for each ASIC X in the switch:
a.
b.
c.
Reading the error register clears the CMEM interrupt bit, preparing for the next offset to test.
Operands This command has the following operands:
--slot slotnumber
-passcnt count
-datatype type
-ports itemlist
-seed value

• interrupt status bits set.
• the error type is buffer number error.
• the port number in error is the receiver port (which is the base port of ASIC Y).
Check that all ASICs besides X are not interrupted or flagged with an error.
Write a 64-byte pattern in the central memory.
Read X from all ASIC Y in the switch.
For all ASIC Y, ensure:
• interrupt status bits set.
• the error type is chip number error.
• the port number in error is the receiver port (which is the base port of ASIC Y).
Specify the slot number on which the diagnostic will operate. The ports specified
will be relative to this slot number. The default is set to 0 and designed to operate
on fixed port-count products.
Specify the number of test passes to run. By default, the test runs one time.
Specify the type of data pattern to use. By default, type 9, QUAD_RAMP, is used.
For a complete list of supported data patterns, run the
Some common settings are:
1 BYTE_FILL pattern
2 WORD_FILL pattern
3 QUAD_FILL pattern
9 QUAD_RAMP (Addr=Data) pattern
11 RANDOM pattern
Specify a list of blade ports to test. The Ports list is translated into a matching Quad
list before the test is run. By default, all the blade ports in the specified slot (--slot)
are tested. Refer to
Specify the data pattern seed to be used. The default seed value is 0.
