6. Check if any of the 8 statistic error counters are non-zero: ENC_in,
CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out, BadOrdSet,
DiscC3.
7. Check if the transmit, receive or class 3 receiver counters are stuck
at some value.
8. Check if the number of frames transmitted is not equal to the
number of frames received.
9. Repeat steps 3 through 8 for all ports present until:
a. Number of frames requested is reached
b. All ports are marked bad
At each pass, the frame is created from a different data type. There are
seven data types:
If seven passes are requested, the seven different data types are used
in the test. If eight passes are requested, the first seven frames are
unique data types, and the eighth is the same as the first.
The
crossPortTest command behaves differently according to the
mode activated.

ports in the same switch are tested. Ports connected outside of the
switch are ignored.
