2 portCmd -q service_type Specifies the type of service in the traceroute request. The default is 0 and service_type must be an integer from 0 to 255. This operand is optional. -w wait_time Sets the time, in milliseconds, to wait for a response to a probe. The default is 5000 milliseconds. The maximum wait time is 9000 milliseconds (9 seconds). This operand is optional. -z size Specifies the size, in bytes, of the trace route packet to use. The default is 64 bytes. In an IPv4 environment, the ICMP/IP header occupies 28 bytes. In an IPv6 environment, it occupies 48 bytes. The total size, including ICMP/IP headers (28 or 48 bytes without IP options), cannot be greater than the IP MTU configured on the interface. This operand is optional. -v vlan_id Specifies 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 is dynamically maintained by the ipperf application. See the portCfg help page for details on creating a VLAN tag table. This option is currently not supported on the Brocade 7800 and FX-24. -c L2 Class-of-Service Specifies Class of Service/Priority, as defined by the IEEE 802.1p specification. Values must be in the range of 0 to 7. The default value is 0. This operand is optional with the -v option. --tperf Determines the path characteristics to a remote host or tunnel destination The -tperf option requires two separate Brocade FX-24 blades to function. One blade plays the role of a data sink and the other blade plays the role of the data source. TPerf also requires that you define a tunnel as a TPerf tunnel. Refer to portCfg fciptunnel for more information. -sink | -source Designates the switch to function either as a data sink or a data source. This operand is required. When -sink is specified, TPerf begins to respond to traffic sent by the switch acting as the data source. The process continues to run until it is either terminated by user intervention (Ctrl +C) or, if a duration is specified with the -t option, until the process completes the set time frame. The following optional arguments are ignored on the data sink, because it services all requests from the data source: --high, --medium, --low, -unidirectional, -random, -pattern, and -size. When -source is specified, TPerf generates traffic until it is interrupted by user intervention (Ctrl + c) or, if a duration is specified with the -t option, until the process completes the set time frame. The TPerf module on the remote host will immediately begin generating traffic; it is therefore imperative that the data sink has been started on the opposing switch before the data source is started on the local switch. TPerf generates statistics every 30 seconds by default unless you specify a different value for -interval. The output displays the following information: Tunnel ID Numeric identifier for the TPerf tunnel. Traffic Priority High, Medium, or Low. bytes tx Number of bytes transmitted. 644 Fabric OS Command Reference 53-1001337-01
