portCmd 2 -z size Specifies the default packet size to a fixed size in bytes. 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. 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. -c L2 Class-of-Service Specifies 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. --traceroute Traces the IP router hops used to reach the host dst_ip from one of the source IP interfaces on the GbE port. Valid arguments include the following: -s src_ip Specifies the local IP address to use for sourcing the probe packets. IPv6 addresses are supported. -d dst_ip Specifies the destination IP address to which to probe the IP router path. IPv6 addresses are supported. -x | -crossport Specifies the source IP address as a crossport. A crossport is the nonlocal (secondary) XGE port to a VE_Port group that provides failover capabilities for the tunnel configured on the local XGE port. This operand is optional and supported only on the Brocade FX8-24 XGE ports. -h max_hops Specifies the maximum hop limit used in the outgoing probe packets. The default value is 30 hops. This operand is optional. -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.
