<para>The following steps show how a Cisco 3750 is configured for pod-level layer-2

switching.</para>

<para>Setting VTP mode to transparent allows us to utilize VLAN IDs above 1000. Since we only
|

use VLANs up to 999, vtp transparent mode is not strictly required.</para>

<para>By default, Cisco passes all VLANs. Cisco switches complain of the native VLAN IDs are
|
||
different when 2 ports are connected together. That’s why you must specify VLAN 201 as the
|
||
native VLAN on the layer-2 switch.</para>
