Enabling or Disabling Control Traffic

By default, the QoS feature for certain critical control traffic is enabled. These critical control frames 
are assigned the highest (absolute) priority. 

</p>
<a name="wp1072483"> </a><p class="pBodyAutonumRel">
<strong>Tip	&nbsp;&nbsp;&nbsp;</strong> We do not recommend disabling this feature as all critical control traffic is automatically assigned the 
lowest priority once you issue this command.
