3. Configure up the routing table so that when port M receives frames, the frames are routed back to the
partner port N and vice versa.
4. Transmit two frames by way of port M and two frames by way of port N. The following four patterns
will be used for the four frames, one pattern each:
• 1000 bytes of CSPAT
• 480 bytes of RDRAM_PAT
• 2112 bytes of BYTE_LFSR
•200 bytes of RANDOM
5. Periodically check status:
a. Each port has not died.
b. Each port's frames-transmitted counter is still incrementing.
c. Each port's statistic error counters are nonzero:
d. ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out, BadOrdSet, DiscC3
e. Until one of the following is met:
• The number of frames requested is met on all selected ports.
• All ports are eventually marked bad.
• The user aborts the procedure.
The path test is repeated for each path, unless it is aborted by a keyboard interrupt. The data is not read
and checked as was done in portLoopbackTest and crossPortTest. There is no CPU intervention
during a path test besides the periodic checks of the hardware counters. At the end of a path test, all
statistics and routes are reset for the next path test.
An example of the data used is as follows:
CSPAT: 0x7e, 0x7e, 0x7e, 0x7e, ...
RDRAM_PAT: 0xff, 0x00, 0xff, 0x00, ...
BYTE_LFSR: 0x69, 0x01, 0x02, 0x05, ...
RANDOM: 0x25, 0x7f, 0x6e, 0x9a, ...
Because this test includes the media and the fiber cable loopback plug in its test path, its results combined
with the results of portLoopbackTest and spinSilk can be used to determine which components of the switch
are faulty.
Operands
The following operands are optional:
--slot slotnumber Specifies the slot number on which the diagnostic operate. The ports
specified are relative to this slot number. The default is set to 0 and
designed to operate on fixed-port-count products.
-nmegs count Specifies the number of million frames to send per path test. The path
test will progress until the specified number of frames has been
transmitted on each port. The default value for count is 1, so the total
number of frames sent will be at least 8 million (1 million frames * 8
paths).
-lb_mode mode Selects the loopback point for the test. By default, miniCycle uses
external (SERDES) loopback.
1 Port Loopback (loopback plugs)
2 External (SERDES) loopback
