bpPortLoopbackTest
2
At each pass, a different data type is used to create the frame from a palette of seven. If a pass of seven
is requested, seven different frames are used in the test. If eight passes, the first seven frames are
unique, and the eighth frame is the same as the first. The data palette of seven consists of the following
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, ...
NOTES
This command does not support High Availability (HA).
This command is currently supported only on the Brocade Encryption platform at a default speed of 4
Gbps and a loopback mode of 7. Use portLoopBackTest on all other platforms.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS
This command has the following operands:
--slot slot
Specifies the slot number on bladed systems.
-nframes count
Specifies the number of frames to send. The test progresses until the specified
number of frames has been transmitted on each port. The default value is 8.
-pklen count
Specifies the size of the packet to be sent. The default is 2112 bytes. The valid
range is 100 to 2112 bytes.
-lb_mode mode
Specifies the loopback point for the test. The Brocade Encryption Platform, only
supports line loopback (lb_mode 7) and lb_mode defaults to 7 when the
parameter is not specified. Mode values are as follows:
1
Port Loopback (loopback plugs)
2
External (SERDES) loopback
7
Back-end bypass & port loopback
8
Back-end bypass & SERDES loopback
-spd_mode mode
Specifies the speed mode for the test. On the Brocade Encryption platforms only a
speed of 4 Gbps is supported and spd_mode defaults to 4 when the parameter is
not specified.
1
Runs test at 1 Gbps (deprecated).
2
Runs test at 2 Gbps.
4
Runs test at 4 Gbps (Default for Encryption platforms).
