spinSilk
777Fabric OS Version 3.1.x/4.1.x Reference Guide
An example of the data used are as follows:
CSPAT: 0x7e, 0x7e, 0x7e, 0x7e, ...
BYTE_LFSR: 0x69, 0x01, 0x02, 0x05, ...
RANDOM: 0x25, 0x7f, 0x6e, 0x9a, ...
RDRAM_PAT: 0xff, 0x00, 0xff, 0x00, ...
At each pass, the frame is created from a different data type. There are seven data
types:
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,...
If seven passes are requested, the 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.
spinSilk Modes
These are the test modes. These modes can be used together to test specific ports.
■ Loopback mode
■ SFP mode
LoopBack Mode (lbmode)
There are four loopback modes that can be used when executing the spinSilk
command. The modes are specified by entering:
■ 0 for cable mode. This loopback mode is the default mode and tests only
M->N connections. It requires that the user connect a cable from one port to a
different port.
■ 1 for single port also loopback mode. This lb_mode tests M->N and M->M
connections.
If M->N cable connections are used, the spinsilk command operates
identically in lb_mode 0 and lb_mode 1.
If M->M loopback plugs are used with SPLB mode disabled, the
spinsilk command will circulate frames between pairs of M->M
connected ports as follows:
P1 TX >>> P1 RX -> P2 TX >>> P2 RX -> P1 TX
