-spd_mode mode
Specifies the speed mode for the test. This parameter controls the speed at which
each port is operated. The speed option chosen or defaulted to must not exceed
the speed capability of the SFP device or the test results will be unpredictable. For
example, if you use an 8 Gbps SFP in a 16 Gbps-supported slot, you must use
spd_mode 8 option to specify 8 Gbps speed.
0
Runs test at 1 Gbps, 2 Gbps, 4 Gbps, and 8 Gbps on 8 Gbps ports. Runs test at
16 Gbps on 16 Gbps ports. (deprecated)
1
Runs test at 1 Gbps (deprecated).
2
Runs test at 2 Gbps.
4
Runs test at 4 Gbps.
8
Runs test at 8 Gbps (Default for 8 Gbps platforms).
10
Runs test at 10 Gbps (Default for 10 Gbps platforms).
16
Runs test at 16 Gbps (Default for 16 Gbps platforms).
-ports itemlist
Specifies a list of blade ports to test. By default, all of the blade ports in the
specified slot (--slot) are used. You must have root access to the bladePortMap
command if you want to map a specific front-end blade port to a user port. You
can also use the -uports option to specify the user ports. Refer to itemList for
more information on the itemlist parameter.
-uports itemlist
Specifies a list of user ports to test. If this operand is omitted, by default the test
will run on all valid blade ports in the slot. Refer to itemList for more information
on the itemlist parameter.
