crossporttest Examples
38
This example will run crossporttest an infinite number of times (or until you
press Enter) and allows ports to be connected to themselves (M-M):
v3.x:admin> crossporttest 0,1
Running Cross Port Test ...
This example will run crossporttest online or offline 100 (default value is 10)
times on slot 2 to the SERDES at 2 Gbit/sec, not all SFPs are looped back, it only
uses ports 4 and 15:
v4.x:admin> crossporttest –nframes 100 –lb_mode 2 –spd_mode 2
–ports 2/4,15

What is displayed when you execute this test depends on the level of verbosity that you have selected.
The diagdebugshow command depicts available levels of debugging. It is not recommended going
over level 5 – there is such a thing as too much information! This setting could adversely effect other
switch operations, so set it back to the default setting after you have finished using it. Depending on
the tests, setting the debugging level high (via the command: setdbg “DIAG”, 9) may generate
more informative messages. Put the debugging mode back to the default by invoking setdbg
“DIAG”,0 because verbose mode (9) could affect the behavior of the switch!
See the diaghelp Reference Guide for a complete “help” output.
nframes count will specify the number of frames to send. The test will progress until the
specified number of frames has been transmitted on each port. The default value is 10.
lb_mode will select the loopback point for the test. By default, crossporttest uses cable
loopback.
spd_mode will specify the speed mode for the test. This parameter is only used for Bloom- based
products where it controls the speed at which each port is operated. The exact operation of each modes
3-6 depends upon the loopback mode selected. When speed modes 3-6 are used with cables, they must
be connected EVEN->ODD or the test will fail.
gbic_mode the option may be used to override the global GBIC mode described above for the
duration of this test. When it is enabled (1) then testing is limited to user ports with media installed.
no_restore this option may be set in order to force the test to skip part of the POST cleanup
normally performed. This may be helpful during debugging. This parameter should normally be left at
the default value of 0.
ports itemlist will specify a list of user ports to test. By default all of the user ports in the
selected slot will be assumed.
