Troubleshooting Commands
run diagnostics
run diagnostics [extended | normal | packet memory] slot [<slot number> |
msm-a | msm-b]
Description
Runs normal or extended diagnostics on the switch, slot, or management module.
Syntax Description
Default
N/A.
Usage Guidelines
If you run the diagnostic routine on an I/O module, that module is taken off-line while the diagnostic
test is performed. The ports on the module do not forward traffic. Once the diagnostic test is completed,
the I/O module is automatically reset and becomes operational again.
NOTE
Run diagnostics when the switch can be brought off-line. The tests conducted are extensive and affect
traffic that must be processed by the system CPU. The diagnostics are processed by the CPU whether
you run them on an I/O or a management module.
On an I/O module, the extended diagnostic routine can require significantly more time to complete,
depending on the number of ports on the module.
The normal diagnostics are short series of tests that do not test all the internal ASIC functions. On a
management module, the extended diagnostic routine tests all components including the internal ASIC
functions. The management module is taken off-line while the diagnostic test is performed. It is reset
and operational once the test is completed.
To view results of normal or extended diagnostics tests, use the following commands:
show diagnostics {slot [msm-a | msm-b | <slot number>]}
If the results indicate that the diagnostic failed, replace the module with another module of the same
type.
extended Runs an extended diagnostic routine. Takes the switch fabric and ports offline,
and performs extensive ASIC, ASIC-memory, packet memory, and packet
loopback tests.
normal Runs a normal diagnostic routine. Takes the switch fabric and ports offline,
and performs a simple ASIC and packet loopback test on all the ports.
packet memory Runs packet memory diagnostics on an “i” series blade or stackable.
slot number Specifies the slot number of an I/O module. This option is available only on
BlackDiamond switches.
msm-a | msm- b Specifies the slot letter of an MSM. This option is available only on
BlackDiamond switches.
