HP StorageWorks 1606 Brocade Fabric OS Command Reference v6.3.0 (53-1001337-01 - Page 101

bpPortLoopbackTest 2 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 slotnumber 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 -spd_mode mode 8 Back-end bypass & SERDES loopback 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). -bpports itemlist 8 Runs test at 8 Gbps (Default for Condor2). 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.
