Operands
This command has the following operands:-
--slot
slotnumber
-nmegs count
-lb_mode mode
-spd_mode mode

Specifies the slot number that the diagnostic will operate on. The ports
specified will be relative to this slot number. The default is set to 0 and designed
to operate on fixed-port-count products.
Specifies the number of frames to send in millions. The test progresses until the
specified number of frames transmits on each port. The default value is 10,
which represents 10 million frames.
Select the loopback point for the test. By default,
loopback.
0 Cable loopback
1 Port loopback (loopback plugs)
2 External (SERDES) loopback
3 Silkscreen loopback
5 Internal (parallel) loopback
Specifies the speed mode for the test. This parameter is used for
Bloom and Condor ASIC-based products only, for which it controls
the speed at which each port operates. For 1G-only products, this
parameter is ignored. The exact operation of modes 5 through 8
depends on the loopback mode selected. When speed modes 5
through 8 are used with cables, they must be connected
EVEN->ODD or the test fails.
0 Run test at 1 Gb/s, 2 Gb/s, and 4 Gb/s.
1 Run test at 1 Gb/s.
2 Run test at 2 Gb/s (Bloom default).
3 Set all even ports' speed for autonegotiate. Set all odd ports' speed
for 1 Gb/s.
4 In test at 4 Gb/s (Condor default). For -lb_mode set to 0,1, the
following speed modes are available to test the speed negotiation.
For -lb_mode set to 0 or 1, the following speed modes are available to test
the speed negotiation:
3 Set all even ports' speed for autonegotiate. Set all odd ports' speed
for 1 Gb/s.
4 Set all even ports' speed for autonegotiate. Set all odd ports' speed
for 2 Gb/s.
5 Set all odd ports' speed for autonegotiate. Set all even ports' speed
for 1 Gb/s.
6 Set all odd ports' speed for autonegotiate. Set all even ports' speed
for 2 Gb/s.
For -lb_mode set to 2,3, the following speed modes are available to test FIFO
underrun.
3,5 Set all even ports' speed for 2 Gb/s. Set all odd ports' speed for
1 Gb/s.
4,6 Set all even ports' speed for 1 Gb/s. Set all odd ports' speed for
2 Gb/s.
