Specifies the number of the slot on which to run the diagnostics. All eligible ports
relative to the slot number are tested. The default is 0 and designed to operate on
fixed-port-count products.
Specifies the number of frames to send. The test progresses until the specified
number of frames has been transmitted on each port. The default value is 10.
Specifies the loopback mode for the test. By default, this test uses the internal
loopback. Valid values depend on the platform on which the command is
executed. Unsupported values are rejected with an appropriate message.
1
Port Loopback (loopback plugs)
2
External (SERDES) loopback
5
Internal (parallel) loopback
7
Backend bypass & port loopback
8
Backend bypass & SERDES loopback (supported only on a chassis)
Specifies the speed mode for the test. This parameter controls the speed at which
each port is operated.
0
Runs test at 2 Gbps, and 4 Gbps.
1
Runs test at 1 Gbps (deprecated).
2
Runs test at 2 Gbps.
