HP StorageWorks 8/80 Brocade Fabric OS Command Reference Manual v6.2.0 (53-100 - Page 618

2 portCmd portCmd Synopsis Diagnoses intelligent ports. portcmd action [slot/]geport arguments Description Use this command to invoke the end-to-end IP path performance (ipperf) characterization feature, or to ping or trace route to a destination IP host from an intelligent GbE port. Notes Virtual LAN (VLAN) tagging is supported on the Brocade FR4-18i and all 7500 platforms that run Fabric OS v6.0.0 or later. To ensure that test traffic traverses the same path as real FCIP traffic would, portCmd supports the VLAN settings as an option. Note that a VLAN tag entry must exist prior to issuing the --ping or --traceroute commands; this includes both the local and remote sides. A VLAN Tag table entry is dynamically maintained by the ipperf application. End-to-end path characterization is not supported if there exists an IPSec-enabled tunnel using the same source/local IP address. 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 For bladed systems only, specify the slot number of the port to be configured, followed by a slash (/). ge port Specifies the port number of the GbE port on the blade. --ipperf -s src_ip -d dst_ip Determines the path characteristics to the remote host. Valid arguments and their values include: Specifies the local IP address to use for sourcing the probe packets. ipperf will not start if there exists an IPSec-enabled tunnel using the same source IP address. IPv6 addresses are supported. Specifies the destination IP address to which to probe the IP router path. IPv6 addresses are supported. -S Specifies the source mode to initiate the TCP connection. The source end-point generates a traffic stream and reports the end-to-end IP path characteristics from this end-point to the receiver end-point sink. -R -i interval -p port -q diffserv Specifies the sink mode to accept the new connection. The end-to-end path characteristics are not reported. Specifies the intervals between polling and displaying statistics, in seconds. If the duration is less than -t running_time, the statistics displays only once, at the conclusion of the test. This operand is optional. Specifies the TCP port number for the listener end-point. This operand is optional. Specifies the DSCP (DiffServ Code Point) marking used for the TCP connection. This operand accepts values between 0 and 63 (inclusive). The default value is 0. 590 Fabric OS Command Reference 53-1001186-01
