• 128 bytes of RANDOM
• 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
There is no CPU intervention besides the periodic checks of the hardware counters.
An example of the data used is as follows:
CSPAT:
BYTE_LFSR:
RANDOM:
RDRAM_PAT:
Because this test includes the media and the fiber cable in its test path, its results, combined with the
results of portLoopbackTest, can be used to determine which components of the switch are faulty.
Operands
This command has the following operands:-
-nmegs count
-lb_mode mode
0x7e, 0x7e, 0x7e, 0x7e, ...
0x69, 0x01, 0x02, 0x05, ...
0x25, 0x7f, 0x6e, 0x9a, ...
0xff, 0x00, 0xff, 0x00, ...
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, but not less, frames have been transmitted on some
ports. The default value is 10, so the number of frames sent will be at least 10
million.
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:
0 Cable loopback
1 Port loopback (loopback plugs)
2 External (SERDES) loopback
3 Silkscreen loopback
4 Internal (parallel) loopback
and
