Operands This command has the following operands:
--slot slotnumber
-nmegs count
-lb_mode mode
-spd_mode mode
2-716
Specifies the slot number on which the diagnostic operates. The ports specified
are relative to this slot number. The default is set to 0 and designed to operate on
fixed-port-count products.
Specify the number of million frames to send. The test progresses until the
specified number of frames has been transmitted on each port. The default value
is 10, so the number of frames sent are at least 10 million.
Specify the loopback point for the test. By default, this command uses loopback
plugs, as described earlier. However, for debug purposes, you can select other
loopback modes, as follows:
1 Port loopback (loopback plugs)
2 External (SERDES) loopback
5 Internal (parallel) loopback
Specify the speed for the test. This parameter is used only for Bloom and Condor
ASIC-based products, where For 1 Gbit/sec-only products, this option is ignored.
The exact operation of modes 5 through 8 depends upon the loopback mode
selected. When speed modes 5 through 8 are used with cables, they must be
connected even to odd or the test fails. Modes include:
0 Run test at 1 Gbit/sec, 2 Gbit/sec, and 4 Gbit/sec (default).
1 Set all port speeds to lock at 1 Gbit/sec
2 Set all port speeds to lock at 2 Gbit/sec.
4 Set all port speeds to lock at 4 Gbit/sec.
For -lb_mode set to 0 or 1, the following speed modes are available to test the
speed negotiation:
5 Set all even ports' speed for auto-negotiate, set all odd ports' speed for 1
Gbit/sec.
6 Set all even ports' speed for auto-negotiate, set all odd ports' speed for 2
Gbit/sec.
7 Set all odd ports' speed for auto-negotiate, set all even ports' speed for 1
Gbit/sec.
8 Set all odd ports' speed for auto-negotiate, set all even ports' speed for 2
Gbit/sec.
For -lb_mode set to 2 or 3, the following speed modes are available to test FIFO
underrun.
5,7 Set all even ports' speed for 2 Gbit/sec, set all odd ports' speed for 1 Gbit/
sec.
6,8 Set all even ports' speed for 1 Gbit/sec, set all odd ports' speed for 2 Gbit/
sec.
