6. Check the eight statistic error counters for nonzero values:
ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF,
Enc_out, BadOrdSet, DiscC3
7. Check the transmit, receive, or class 3 receiver counters to see if they are
stuck at some value.
8. Check that the number of frames received is equal to the number of frames
transmitted.
9. Repeat steps 3 through 8 for all ports present until the number of frames
(or
passCount
) requested is reached or all ports are marked bad.
At each pass, the frame is created from a different data type. If seven passes
are requested, seven different data types are used in the test. If eight passes
are requested, the first seven frames use unique data types, and the eighth is
the same as the first. The seven data types are:
1.
CSPAT
:
0x7e, 0x7e, 0x7e, 0x7e, ...
2.
BYTE_LFSR
:
0x69, 0x01, 0x02, 0x05, ...
3.
CHALF_SQ
:
0x4a, 0x4a, 0x4a, 0x4a, ...
4.
QUAD_NOT
:
0x00, 0xff, 0x00, 0xff, ...
5.
CQTR_SQ
:
0x78, 0x78, 0x78, 0x78, ...
6.
CRPAT
:
0xbc, 0xbc, 0x23, 0x47, ...
7.
RANDOM
:
0x25, 0x7f, 0x6e, 0x9a, ...
One of the three following modes can be activated; the test produces
different results for each mode:
• switchEnable/switchDisable mode
• singlePortAlso mode
• GBIC mode
