An offline test is a disruptive test that exercises all port connections for a switch in 
the diagnostics state. You must place the switch in the diagnostics state using the 

 command before starting the test. There are two types of offline 

test: internal loopback and external loopback.

„

An internal loopback test exercises all internal port connections.

„

An external loopback test exercises all internal port and transceiver 
connections. A transceiver with a loopback plug is required for all ports.

The following example performs an offline internal loopback test on a switch:

SANbox #> admin start

SANbox (admin) #>set switch state diagnostics

SANbox (admin) #> test switch 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)   [100    ]

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

When the test is complete, remember to place the switch back online. The switch 
resets when it leaves the diagnostics state.
