switch:admin> sramRetentionTest
Running SRAM Retention Test ... passed.
Figure 4-7. sramRetentionTest command example
NOTE:
Related error messages are DIAG-REGERR, DIAG-REGERR_UNRST, and
DIAG-BUS_TIMEOUT.
cmemRetentionTest
Figure 4-8 shows the
cmemRetentionTest
command, which verifies that data
written into the SRAMs that make up the central memory is retained and that
data bits do not decrease when read after some amount of delay since the
write.
IMPORTANT:
This test cannot be executed on an operational switch. Before issuing the
cmemRetentionTest command, disable the switch using the switchDisable
command.
switch:admin> cmemRetentionTest
Running cmemRetention Test .. passed.
Figure 4-8. cmemRetentionTest command example
NOTE:
Related error messages are DIAG-LCMEM, DIAG-LCMRS, and DIAG-LCMTO.
crossPortTest
Figure 4-9 shows the
crossPortTest
command, which verifies the intended
functional operation of the switch. Each port’s transmitter sends frames by
means of the GBIC module and external cable to another port’s receiver. This
test exercises the entire path of the switch.
You can connect any port to any other port in the same switch provided the
connection is of the same technology, for example, GBIC-SW ports to
GBIC-SW ports and GBIC-LW ports to GBIC-LW ports.
NOTE:
All ports on the switch must be connected if the GBIC mode is disabled or if the
switch shows an error condition. When running the Cross Port test, set the operating
mode value to 0 or 1.
