bpPortLoopbackTest

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.
2 Runs test at 2 Gbps.
4
Runs test at 4 Gbps (Default for Encryption platforms).
8
Runs test at 8 Gbps (Default for Condor2).
-bpports itemlist
Specifies a list of blade ports to test. By default all valid blade ports in the
specified blade are tested. On the Brocade Encryption platforms, ports
80-103 are the only valid ports, because these are the only blade ports with
access to the Vader chip. Refer to the itemlist help page for further
information on the itemlist parameter.
Examples
To run the test on blade ports 80-90 with one frame:
switch:admin>
bpportloopbacktest -bpports 80-90 -nframes 1
