2 cmemRetentionTest cmemRetentionTest Tests the data retention of the central memory SRAMs. Synopsis cmemretentiontest [--slot slotnumber][-passcnt count][-datatype type][-ports itemlist][-seed value] Description Use this command to verify that data written into the central memory SRAMs in the ASIC pair is 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 to verify that the data read matches the data previously written. The process is then repeated using the reverse version of the pattern. This command cannot be executed on an enabled switch. You must first disable the switch using the switchDisable command. This command is supported only on Brocade 3250, 3850, 3900, and 24000 platforms. The execution of this command is subject to Admin Domain restrictions that may be in place. Operands This command has the following operands: --slot slotnumber 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. -passcnt count Specify the number of test passes to run. By default, the test will be run one time. -datatype type 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 dataTypeShow command. Some common settings are: Pattern Type Example BYTE_FILL 1 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 WORD_FILL 2 0000 0000 0000 0000 0000 0000 0000 0000 QUAD_FILL 3 00000000 00000000 00000000 00000000 QUAD_RAMP9 00000000 00000001 00000002 00000003 RANDOM 11 55 16 fc d7 17 65 a9 87 5f 44 be 5a d0 de bc a5 -ports itemlist 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 the itemList help pages for further details. -seed value Specify the data pattern seed to be used. The default seed value is 0.
