4 WAN performance analysis tools Ipperf options Please refer to Brocade Fabric OS Command Reference Manual or the man pages for definitive command syntax and option descriptions. Ipperf options are repeated here for convenience. portCmd --ipperf [slot]/ge0|ge1 -s source_ip -d destination_ip -S|-R [-r rate] [-z size] [-t time] [-i interval] [-p port] [-q diffserv] [-v vlan_id] [-c L2_Cos] Where: -s source_ip The source IP address. -d destination_ip The destination IP address. -S Operates the WAN tool FCIP port-embedded client in the sender mode. The test endpoint will generate a traffic stream and report the end-to-end IP path characteristics from this endpoint toward the receiver endpoint. This option cannot be used with the -R option. -R Operates the WAN tool FCIP-port embedded client in the receiver mode. The test endpoint will accept a connection and traffic stream from the sender This option cannot be used with the -S option. -r rate The committed rate for the data stream in Kb/s. If specified, the traffic generator will be limited by a traffic shaper. This can be used to characterize the end-to-end IP path performance based on the data rate to be configured for a tunnel between the same endpoints. If a rate is not specified then the traffic generator will compete for uncommitted bandwidth. -z size The size in bytes for each buffer handed to the TCP layer. If a size is not specified, the maximum size data buffer will be used based on the outbound IP interface MTU. The size is the only buffer size that will be handed over to the TCP layer. -t time The total time in seconds to run the test traffic stream. If a time is not specified, the test will run continuously until stopped by typing ctrl-C. -i interval The interval in seconds between polling and printing stats. The default is 30 sec. If this time is greater than the running time (specified by -t), the stats will be printed only once at the conclusion of the test. -p port The TCP port number for the listener endpoint. If a TCP port is not specified, port 3227 is used (this is next port after ports 3225 and 3226, which are used for the FCIP tunnel connections). -q diffserv The DiffServ marking code point (DSCP) for the TCP connection. The value must be an integer in the range of 0 to 63. The default value is 0. This operand is optional. Before configuring DSCP settings, determine if the IP network you are using implements PHB, and consult with the network administrator to determine the appropriate DSCP values. -v vlan_id The VLAN ID. Values must be in the range of 1 - 4094. There is no default value. Note that a VLAN tag entry must exist on the local and remote sides prior to issuing the -v option. A VLAN Tag table entry will be dynamically maintained by the ipperf application. -c L2_Cos The Class of Service/Priority as defined by IEEE 802.1p. Values must be in the range between 0 and 7. The default is 0. This operand is optional with the -v option 78 Fabric OS FCIP Administrator's Guide 53-1001766-01
