sramRetentionTest Performs a data retention test of the miscellaneous SRAMs in ASIC. Synopsis sramretentiontest [--slot slotnumber][-passcnt count][-ports itemlist][-skip bitmask][-delay value] Availability admin Description Use this command to verify that data written into the miscellaneous SRAMs in the ASIC are retained after a 10-second wait. The method used is to write a fill pattern to all SRAMs, wait 10 seconds, and then read all SRAMs, checking that the data read matches the data previously written. The test is repeated using the inverted version of the pattern. The test will use four QUAD_FILL patterns and one QUAD_RAMP pattern with random seed. The first four QUAD_FILL patterns are: 0xffffffff 0x55555555 0x33333333 0x0f0f0f0f0f For details about the patterns used in diagnostic tests, see the dataTypeShow command. NOTE: The sramRetentionTest 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: --slot slotnumber -passcnt count -ports itemlist -skip bitmask -delay value Specify the number of the slot on which the diagnostic operates. The ports specified are relative to this slot number. The default is set to 0 and designed to operate on fixed-port-count products. Specify the number of times to execute this test. The default value is 1. Specify a list of blade ports to test. By default, all the blade ports in the specified slot are used. See itemList for more details. Specify patterns to omit in the test. This command uses the data patterns described in the section above by default. Using this option, you can intentionally omit one or more patterns, if needed. Specify the delay between the read and write, in seconds. The default value is 10 seconds.
