portCmd
The following arguments are optional:
-high
-medium
-low
-time duration
-unidirectional
-random
-pattern pattern
706
-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.
Generates high priority traffic.
Generates medium priority traffic.
Generates low priority traffic.
If no traffic priority is specified only medium priority traffic is generated.
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.
Generates traffic in one direction only. The default is round-trip.
Specifies a random protocol data unit (PDU) size between 2048 and the size of
the send request. Refer to -size below.
Specifies the test data pattern for the payload as one of the following values:
0 | notspecified
No pattern is specified. TPerf applies whatever is already set or in memory. This is
the default value.
1 | allzeros
The specified pattern is "all zeros".
2 | allones
The specified pattern is "all ones".
3 | incrementingbyte
The specified pattern is "incrementing byte".
4 | random
The specified pattern is "random".
5 | jitter
The specified pattern is "jitter".
