-lb_mode mode
(V4.1.x only)
Specify the loopback mode for the test. By default, this
test uses internal loopback. Valid values are as follows:
1 Port Loopback (loopback plugs)
2 External (SERDES) loopback
5 Internal (parallel) loopback
-spd_mode mode
(V4.1.x only)
Specify the speed mode for the test. For 1 Gbit/sec only
products it is ignored. The exact operation of modes 3
through 6 depends upon the loopback mode selected.
When speed modes 3 through 6 are used with cables,
they must be connected EVEN to ODD or the test will fail.
■
0: set all ports' speed for auto-negotiate.
■
1: set all ports' speed to lock at 1 Gbit/sec.
■
2: set all port's speed to lock at 2 Gbit/sec.
For
lb_mode
== 0,1 the following speed modes are
available to test the speed negotiation:
■
3: set all even ports' speed for auto-negotiate, set all
odd ports' speed for
1 Gbit/sec.
■
4: set all even ports' speed for auto-negotiate, set all
odd ports' speed for
2 Gbit/sec.
■
5: set all odd ports' speed for auto-negotiate, set all
even ports' speed for
1 Gbit/sec.
■
6: set all odd ports' speed for auto-negotiate, set all
even ports' speed for
2 Gbit/sec.
For
lb_mode
== 2,3 the following speed modes are
available to test fifo underrun.
■
3,5: set all even ports' speed for 2 Gbit/sec, set all
odd ports' speed for 1 Gbit/sec.
■
4,6: set all even ports' speed for 1 Gbit/sec, set all
odd ports' speed for 2 Gbit/sec.
-ports itemlist
(V4.1.x only)
Specify a list of user ports to test. By default all of the user
ports in the current switch are tested. This option may be
used to restrict testing to the specified ports.
