centralMemoryTest
Preform a bit write and 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 central
memory.
Note: This command may not be executed on an enabled switch. You must first disable the switch
using the switchDisable command.
Operands This command has the following operands:
passCount Specify the number of times to execute this test. The default passcount is 1. This
operand is optional.
dataType Specify the data type to use when writing the central memory. The
dataTypeShow command lists data types allowed. The default datatype value is
QUAD_RAMP. This operand is optional.
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. The default
value for dataseed is a randomly generated number. This operand is optional.
