Dell Brocade G620 Brocade 8.0.1 Fabric OS Command Reference - Page 777

portCmd -f first_ttl Specifies the starting point for the "time to live" parameter. The default is 1. The command skips processing for those intermediate gateways that are less than the first_ttl hops. This operand is optional. -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 between 1 and 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. See the portCfg help page for details on creating a VLAN tag table. This option is supported on Brocade FX8-24 blade only. -c L2 Class-of-Service Specifies Class of Service/Priority, as defined by the IEEE 802.1p specification. Values must be in the range between 0 and 7. The default value is 0. This operand is optional with the -v option. --help Displays command usage. --tperf Determines the path characteristics to a remote host or tunnel destination. The -tperf option requires two separate Brocade FX8-24 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. This option is supported on Brocade FX8-24 blade only. -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 value for duration is specified with the -t option, until the process completes the set time frame.
