    3. Double-click on the frame you want.

    4. When you are finished adding frames, click Ok. The added frame(s) appears in the Frame Display Area.

Note: The Length field gets calculated and updated automatically. The Exerciser cannot send a frame with length less than 64 bytes.

Frame Display Area

Setting/Control

Description

Frame number

Counts the number of frames from 1 through total

Frame

Name of selected frame

Repeat Count

Number of times to repeat each frame

Burst Count

Number of bursts for the Repeat Count. This field is only active in Burst-Interleave Transmission Mode.

Note: Repeat Count must be a Multiple of the Burst Count.

Mean IPG

Interpacket Gap: You can set the IPG in bytes or nanoseconds.

Note: The minimal IPG is speed-dependent and automatically set by the software.

Protocol Error

You can inject errors from the drop-down menu. The default is Per Port Error Settings, as defined in the bottom pane of the dialog.

Payload Length

Length of data to be included in the frame:

  • Fixed

  • Random: Enter range from minimum to maximum)

  • Incremental: Min, Max, and Step

Note:The payload length field gets calculated and updated automatically.

The payload length is only incremented for frames that are repeated when the Repeat Counter is used.

The payload length is limited to 1999 bytes.

Payload

Define the Payload:

Select the Pattern Type, then select the Payload Pattern Size and specify the Payload Pattern that will be repeated up to the Payload Length.

  • Fixed: Always sends the same thing.

  • Incremental: Increments the Payload Pattern by the Step.

  • Random: Creates a random pattern the size of Payload Length.

Custom

Define exactly what you want the pattern to be, or you can import a file.

Transmission Settings

Setting

Description

Transmission Mode

Sequential: Frames are sent out according to the order defined in the top pane. Each frame is repeated as many times as specified in “Repeat Count” settings for that frame.

Interleave: One frame is sent from each row in the top pane, until each one reaches “Repeat Count” settings.

Burst-Interleave: “Burst Count” bursts, each of “Repeat Count” frames, are sent from each frame defined in the top pane.

Mean Burst Gap

Only applicable in Burst-Interleave Mode. This is the gap (defined in either bytes or nanoseconds) between consecutive bursts of frames (between each frame in the burst, the defined IPG will remain).

Stop transmission after sending

Stop sending frames after a set number of frames or milliseconds

Example Transmission Mode

Option

Example

Interleave

For example, if 3 frames have been defined:

  • A (Repeat Count=3)

  • B (Repeat Count=2)

  • C (Repeat Count=1)

The sequence of sending frames is:

  • A, B, C

  • A, B

  • A

  • A, B, C

  • A, B

... then the above sequence repeats. (Sequence repeats until the “Stop transmission” conditions have been met.)

Burst-Interleave

For example, if 3 frames have been defined:

  • A (Repeat Count=9, Burst Count=3)

  • B (Repeat Count=6, Burst Count=3)

  • C (Repeat Count=3, Burst Count=3) The sequence of sending frames is:

  • A, A, A

  • B, B, B

  • C, C, C

  • A, A, A

  • B, B, B

  • A, A, A

... then the above sequence repeats. (Sequence repeats until the “Stop transmission” conditions have been met.)
