Offline tests for ports
An offline test is a disruptive test that exercises the port connections. You must place the port in the
diagnostics state using the
set port
command before starting the test. There are two types of offline test:
internal loopback and external loopback.
• An internal loopback test exercises the internal port connections.
• An external loopback test exercises the port and its transceiver. A transceiver with a loopback plug is
required for the port.
The following example performs an offline test:
SN6000 FC Switch #> admin start
SN6000 FC Switch (admin) #> set port 1 state diagnostics
SN6000 FC Switch (admin) #> test port 1 offline internal
A list of attributes with formatting and current values will follow. Enter a new
value or simply press the ENTER key to accept the default value. If you wish to
terminate this process before reaching the end of the list press 'q' or 'Q' and
the ENTER key to do so.
LoopCount (decimal value, 1-4294967295) [429496729]
FrameSize (decimal value, 40-2148) [256 ]
DataPattern (32-bit hex value or 'Default') [Default ]
StopOnError (True / False) [True ]
LoopForever (True / False) [False ]
Do you want to start the test? (y/n) [n] y
The test has been started.
A notification with the test result(s) will appear
on the screen when the test has completed.
SN6000 FC Switch (admin) #>
Test for port 1 Passed.
When the test is complete, remember to place the port back online.
SN6000 FC Switch (admin) #> set port 1 state online
Displaying port test results
You can display the test status while the test is in progress by entering the
test status port
command, as shown in the following example:
SN6000 FC Switch #> test status port 1
Port Test Test Loop Test
Num Port Type Status Count Failures
---- -------- ---- ------ ----- --------

Canceling a port test
To cancel a port test that is in progress, enter the
test cancel port
command.
