Configuring RSPAN

</h1>
<a name="wp1551506"> </a><p class="pBody">
The RSPAN tunnel begins in the source switch and terminates in the destination switch. This section 
assumes Switch S to be the source and Switch D to be the destination. 

</p>
<a name="wp1551507"> </a><h2 class="pHeading2">
Prerequisites 
</h2>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1551508"> </a><li class="pSmartList1">In addition to the source and destination switches, the VSAN must also be configured in each Cisco 
MDS switch in the Fibre Channel fabric, if they exist.
</li>
</ul></div>
<a name="wp1551509"> </a><h2 class="pHeading2">
Detailed Steps
</h2>
<a name="wp1551511"> </a><p class="pBody">
To monitor network traffic using the RSPAN feature, follow these steps:

</p>
<div class="pSmartList1"><ol type="1" class="pSmartList1">
<a name="wp1551512"> </a><li class="pSmartList1">Create VSAN interfaces in destination switch (Switch D) and source switch (Switch S) to facilitate the 
Fibre Channel tunnel (FC tunnel) creation.
</li>
<a name="wp1551513"> </a><li class="pSmartList1">Enable the FC tunnel in each switch in the end-to-end path of the tunnel.
</li>
<a name="wp1551514"> </a><li class="pSmartList1">Initiate the FC tunnel (in Switch S) and map the tunnel to the VSAN interface’s IP address (in Switch 
D) so all RSPAN traffic from the tunnel is directed to the SD port.
</li>
<a name="wp1551516"> </a><li class="pSmartList1">Configure SD ports for SPAN monitoring in the destination switch (Switch D).
</li>
<a name="wp1551517"> </a><li class="pSmartList1">Configure the ST port in the source switch (Switch S) and bind the ST port to the FC tunnel.
</li>
<a name="wp1551518"> </a><li class="pSmartList1">Create an RSPAN session in the source switch (in Switch S) to monitor network traffic.
</li>
