Running Diagnostics on I/O and Management Modules—Modular
Switches Only
If you run the diagnostic routine on an I/O module, that module is taken offline while the diagnostic
test is performed. Traffic to and from the ports on that I/O module is temporarily unavailable. When
the diagnostic test is complete, the I/O module is reset and becomes operational again.
If you run diagnostics on an MSM, that module is taken offline while the diagnostics test is performed.
When the diagnostic test is complete, the MSM reboots and becomes operational again.
After the switch runs the diagnostic routine, test results are saved in the module’s EEPROM and
messages are logged to the syslog.
To run diagnostics on I/O or MSM modules, use the following command:
run diagnostics [extended | normal] slot [<slot> | A | B]
Where the following is true:
●
extended
—Takes the switch fabric and ports offline and performs extensive ASIC, ASIC-memory,
and packet loopback tests. Extended diagnostic tests take a maximum of 15 minutes. The CPU is not
tested. Console access is available during extended diagnostics.
●
normal
—Takes the switch fabric and ports offline and performs a simple ASIC and packet loopback
test on all ports.
●
<slot>
—Specifies the slot number of an I/O module. When the diagnostics test is complete, the
system attempts to bring the I/O module back online.
NOTE
On the BlackDiamond 8810 switch (formerly known as Aspen), if you run diagnostics on slots 5 and 6 with an
MSM installed in those slots, the diagnostic routine tests the I/O subsystem of the MSM. To run diagnostics on
the management portion of the master MSM, specify slot A or B.
●
A | B—Specifies the slot letter of the master MSM. The diagnostic routine is performed when the
system reboots. Both switch fabric and management ports are taken offline during diagnostics.
Running Diagnostics on the Summit X450 Switch Only
If you run the diagnostic routine on a Summit X450 switch, the switch reboots and then performs the
diagnostic test. During the test, traffic to and from the ports on the switch is temporarily unavailable.
When the diagnostic test is complete, the switch reboots and becomes operational again.
After the switch runs the diagnostic routine, test results saved to the switch’s EEPROM and messages
are logged to the syslog.
To run diagnostics on the Summit X450 switch, use the following command:
run diagnostics [extended | normal]
Where the following is true:
●
extended
—Reboots the switch and performs extensive ASIC, ASIC-memory, and packet loopback
tests. Extended diagnostic tests take a maximum of 5 minutes. The CPU is not tested.
●
normal
—Reboots the switch and performs a simple ASIC and packet loopback test on all ports.
