ST Port

</h1>

In the SPAN tunnel port (ST port) mode, an interface functions as an entry point port in the source switch 
for the RSPAN Fibre Channel tunnel. The ST port mode and the remote SPAN (RSPAN) feature are 
specific to switches in the Cisco MDS 9000 Family. When configured in ST port mode, the interface 
cannot be attached to any device, and thus cannot be used for normal Fibre Channel traffic (see the <em class="cEmphasis">Cisco 
MDS 9000 Family NX-OS System Management Configuration Guide</em>). 

</p>
<a name="wp1072790"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> ST port mode is not supported on the Cisco MDS 9124 Fabric Switch, the Cisco Fabric Switch for HP 
c-Class BladeSystem, and the Cisco Fabric Switch for IBM BladeCenter.
