cmemRetention test
Table 31 shows the
cmemRetentionTest
command, which is used to verify that
data written into the SRAMs that make up the central memory are retained and that
data bits do not
drop
when read after some amount of delay since the write
operation.
Attention:
This command cannot be executed on an operational switch. Before
using the
cmemRetention test
command, disable the switch using the
switchDisable
command.
cmemRetention test example:
The
cmemRetention Test
command performs a
data retention test of the central memory SRAMs.
Table 31. cmemRetention test example
Synopsis
cmemRetentionTest [passCount]
Availability
Administrator
Description
Use this command to verify for data retention in the central memory
SRAMs in the ASIC.
Below are possible error messages if failures are detected:
DIAG-LCMRS
DIAG-LCMTO
DIAG-LCMEM
Operands
This command has the following operand:
passCount
Specify the number of times to execute this test. The
default value is 1. This operand is optional.
Example
sw7:admin> cmemRetentionTest
Running CMEM Retention Test ... passed.
Related error messages:
DIAG-LCMEM, DIAG-LCMRS, DIAG-LCMTO.
cmiTest
Table 32 on page 97 shows the
cmiTest
command, which verifies that control
messages can be correctly sent from any ASIC to any ASIC. It also tests that the
checksum check is OK.
Attention:
This command cannot be executed on an operational switch. Before
issuing the
cmiTest
command, disable the switch using the
switchDisable
command.
cmiTest example:
The
cmiTest
command performs a ASIC to ASIC connection
test of the CMI bus
