4. Press the stream's Number Button under in
burst of packets, for the configured burst size.
When done inserting bursts configuring the stream for transmitting at a
Constant %BW rate, set the Burst Size back to 1 to avoid "bursty" transmissions.
Inserting a Pause (Flow Control) into a Stream
Pausing frames is a means of flow control that specifies how long the transmitting
device should remain quite. The flow control gives limited ability to regulate a (high
bandwidth) source by sending pause frames to the source. Inserting a pause into a
stream causes the source to stop sending frames for a specified amount of time
(Quanta), allowing the (low bandwidth) receiver to catch up and process queued
frames.
Important: Flow Control must be enabled in order to count received Pause
Packets.
Important: Pause is not available when IP Reflection is enabled.
To start insert a Pause frame in a packet stream:
1. Select Config and choose Set.
2. Select Pause. The Enter Pause Quanta keypad appears.
3. Enter a Pause Quanta value and select OK.
A quanta is the unit of time required for transmitting 512-bits at the speed of the
port.
The number of quanta (N x 512-bits) indicate the duration of the pause.
Valid pause quanta values are 0-65535.
A pause frame with a pause quanta of 0 indicates a resume frame to restart the
paused traffic.
