<div><div class="section"> <p>Ethernet networks break data up into many little chunks called
|
||
|
|
frames. These frames are sent individually across the network and reconstructed
|
||
|
|
by the receiving computer. Changing the size of the frames can alter the behavior
|
||
|
|
of the network. Changing the frame size is possible for both TCP/IP over Ethernet
|
||
|
|
networks and SNA over Ethernet networks. </p>
|
||
|
|
<p>Your frame size might need
|
||
|
|
adjusting if the remote bridge drops your frames. For more information about
|
||
|
|
remote bridges dropping frames, see Remote bridges dropping frames.</p>
|
||
|
|
<p>To
|
||
|
|
change your frame size do the following:</p>
