Troubleshooting Commands
You can run up to two diagnostics tests at the same time.
To view results of normal or extended diagnostics tests, use the following commands:
• On an “ i ” series switch:
show diagnostics {slot [msm-a | msm-b | msm-c | msm-d | <slot number>]}
• On an “ e ” series switch:
show diagnostics
For the “i” Series Switches. If you run the diagnostic routine on an I/O module in an “ i ” series
switch, that module is taken off-line while the diagnostic test is performed. The ports on the module do
not forward traffic. When the diagnostic test is completed, the I/O module is automatically reset and
becomes operational again.
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.
For the BlackDiamond Switches. To configure a BlackDiamond switch to run diagnostics on an
MSM at boot-up, use the following command:
configure diagnostics [extended | fastpost | normal | off]
Example
The following command runs extended diagnostics on the module in slot 3 of a BlackDiamond chassis:
run diagnostics extended slot 3
A warning is displayed about the impact of this test, and you have the opportunity to continue or
cancel the test.
Running extended diagnostics will disrupt network traffic on the system.
Extended diagnostic will also execute Packet Memory Scan........
WARNING: Device may be taken offline. To prevent this
first configure "sys-health-check auto-recovery online"
Are you sure you want to continue? yes/no
y
Extended diagnostics can cause the following messages to appear in the log:
<CRIT:SYST> task tdiagTask cpu utilization is 98% PC: 806266e8
<INFO:SYST> task tdiagTask cpu utilization is 98% PC: 806266e8
You can ignore these messages; they indicate that the system is busy running the diagnostics.
