Telnet Commands 27
centralMemoryTest
Bit write/read test of the ASIC central memory.
Synopsis
centralMemoryTest [passCount, dataType, dataSeed]
Availability admin
Description Use this command to verify the address and data bus of the ASIC SRAMs
that serve as the central memory.
Note
This command cannot be executed on an operational switch. You
must first disable the switch using the switchDisable command.
Operands This command has the following operands:
If all operands are omitted, the default values are 1 for
passCount
,
QUAD_RAMP
for
dataType
, and a random value for
dataSeed
.
Example To test the ASIC central memory:
passCount
Specify the number of times to execute this test.
dataType
Specify the data type to use when writing the central
memory. The
dataTypeShow
command lists data
types allowed.
dataSeed
Specify 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.
