-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 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.
--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.
-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.
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 value for 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.
The following arguments are optional:
-high
Generates high priority traffic.
-medium
Generates medium priority traffic.
-low
Generates low priority traffic.
If no traffic priority is specified only medium priority traffic is generated.
-time duration
Specifies the duration of the TPerf traffic flow in seconds. If a value for duration is
not specified, the process continues to run until it is terminated with Ctrl + C.
-unidirectional
Generates traffic in one direction only. The default is round-trip.
-random
Specifies a random protocol data unit (PDU) size between 2048 and the size of
the send request. Refer to -size below.
