Tests that would jeopardize data transmission require taking the switch offline. If the
switch is not offline, a prompt is displayed before the test is allowed to proceed.
Note:
Taking the switch offline disrupts switch operation.
Switch online
Pressing Enter while
Switch online
is selected activates the display shown in
Figure 45.
After the switch is offline, proceed with the test.
Running diagnostics using Telnet
All Telnet commands are case-sensitive and, therefore, must be entered exactly as
described in the following text.
The following tests are available from the local Telnet port of the switch:
v
Switch offline test (switchDisable)
v
Memory test (ramTest)
v
Port register test (portRegTest)
v
Central memory test (centralMemoryTest)
v
CMI conn test (cmiTest)
v
CAM test (camTest)
v
Port loopback test (portLoopbackTest)
v
Cross port test (crossPortTest)
v
Spin silk test (spinSilk)
v
SRAM data retention test (sramRetentionTest)
v
CMEM data retention test (cmemRetentionTest)
v
Switch online test (switchEnable)
Press Ctrl+C+Enter to abort, continue, view stats, or log test results. Once you
press Ctrl+C+Enter, you receive the message:
Diags: (Q)uit, (C)ontinue, (S)tats, (L)og
v
Enter Q to abort the diag test
v
Enter C to continue testing
v
Enter S to view
......
v
Enter L to save results
.........
Note:
See the “Diagnostic error messages” on page 122 for the actual error
message descriptions.
