Attention:
This command cannot be executed on an operational switch. Before
using the camTest command, disable the switch using the switchDisable
command.

centralmemorytest
Table 30 shows the centralMemoryTest command which verifies that the central
memory in each loom ASIC is functioning correctly by checking the following:
v
The built-in-self-repair (BISR) circuit in each loom chip does not report a failure to
repair bad cells (bisr test).
v
The data cells are uniquely written and then read correctly (data write/read test).
v
The data in any one ASIC is read from any other ASIC (loom connection test).
v
Bad parity is detected and flagged in the error register and posts an interrupt
(parity error test).
v
Buffer number errors are detected and flagged in the error register and post an
interrupt (buffer number error test).
v
Chip number errors are detected and flagged in the error register and post an
interrupt (chip number error test).
Pressing Enter while centralMemoryTest is selected displays a reminder to take
the switch offline, if it is not offline. If the message is displayed, take the switch
offline.
centralMemoryTest example:
The centralMemoryTest command performs a bit
write and read test of the ASIC central memory.

Synopsis
centralMemoryTest [passCount, dataType, dataSeed]
Availability
Administrator
Description
Use this command to verify the address and data bus of the ASIC
SRAMs that serve as the central memory.
Below are possible error messages if failures are detected:
DIAG-TIMEOUT
DIAG-BADINT
DIAG-CMERRTYPE
DIAG-CMERRPTN
Operands
This command has the following operands. If all are omitted, the default
values used are 1 for passCount, QUAD_RAMP for dataType, and a
random value for dataSeed.
passCount
The number of times to execute this test.
dataType
The data type to use when writing the central memory.
The dataTypeShow command lists data types
allowed.
dataSeed
The initial seed value used in generating the data
pattern. For example, a QUAD_RAMP pattern with a
seed value of 0xdead is as follows: 0xdead, 0xdeae,
0xdeaf, 0xdeb0, ...
Some data types, such as BYTE_LFSR, do not require
a seed value.
