• 512 bytes of RDRAM_PAT
The partner port N eventually sends four similar frames, as follows:
• 2112 bytes of BYTE_LFSR
• 928 bytes of CSPAT
• 200 bytes of RANDOM
• 480 bytes of RDRAM_PAT
5. Periodically check the following:
a. No port has died.
b. Each port's frames-transmitted counter is still incrementing.
c. Each port's statistic error counters is nonzero—ENC_in, CRC_err, TruncFrm, FrmTooLong,
BadEOF, Enc_out, BadOrdSet, DiscC3—until one of the following is met:
• The number of million frames requested per port is met.
• All ports are eventually marked bad.
• You send a keyboard (or button) interrupt to abort.
The data is not read and checked, as with the portLoopbackTest and crossPortTest commands. There
is no CPU intervention besides the periodic checks of the hardware counters.
An example of the data used is as follows:
CSPAT: 0x7e, 0x7e, 0x7e, 0x7e, ...
BYTE_LFSR: 0x69, 0x01, 0x02, 0x05, ...
RANDOM: 0x25, 0x7f, 0x6e, 0x9a, ...
RDRAM_PAT: 0xff, 0x00, 0xff, 0x00, ...
Because this test includes the media and the fiber cable 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.

The execution of this command is subject to Admin Domain restrictions that may be in place.
Operands This command has the following operands:
-nmegs count Specify the number of million frames to send. The test will progress until the
specified number of frames has been transmitted on each port. The test result
might display that more frames have been transmitted on some ports, but not less.
The default value is 10, so the number of frames sent will be at least 10 million.
-lb_mode mode Specify the loopback point for the test. By default, spinSilk uses loopback plugs
as described earlier; however, for debugging purposes, you can select other
loopback modes, as follows:
1 Port loopback (loopback plugs)
2 External (SERDES) loopback
3 Silkscreen loopback
5 Internal (parallel) loopback
