-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.
