<h4 id="rzahjper-maxframesizeref">Maximum frame size (MAXFRAME) parameter</h4>
|
|
<p>The maximum frame size is specified in the MAXFRAME parameter in the line
|
|
and controller descriptions. Larger frame sizes generally supply better performance.
|
|
Large frame sizes may not work well for error-prone lines or networks because
|
|
longer times are required to transmit large frames when errors are encountered.</p>
|
|
<p>For each line type, set these maximum frame sizes in the line description.</p>
|
|
<p>To take advantage of these large frame sizes, these values must be configured
|
|
correctly. The MAXFRAME parameter on the line description and controller description
|
|
must reflect the maximum value.</p>

|
|
<div class="notebody">For X.25, increase the DFTPKTSIZE
|
|
parameter value and MAXFRAME parameter value to its maximum value.</div>
|
|
<p>Having configured a large frame size does not negatively affect performance
|
|
for small transfers. Note that both the server and the other link station
|
|
must be configured for large frames. Otherwise, the smaller of the two maximum
|
|
frame size values are used in transferring data. Bridges may also limit the
|
|
frame size.</p>
