• 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:
ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out, BadOrdSet, DiscC3
6. 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
5 Internal (parallel) loopback
7 Backend bypass and port loopback
8 Backend bypass and SERDES loopback
9 Backend bypass and internal loopback
-spd_mode mode Specifies the speed mode for the test. This parameter is only used for Bloom and
Condor ASIC-based products, for which this parameter controls the speed at
which each port operates. For 1 Gbit/sec-only products, this parameter is ignored.
