Changing Your Cisco Switch Database Manager (SDM) Templates to Support IPv4/IPv6 Dual Stack
The following video tutorial will walk you through the manipulation of the Cisco Switch Database Manager (SDM) feature. This feature is not well known and is a very powerful tool that will allow you to change your Ternary Content Addressable Memory (TCAM) table to support a number of different use cases, like IPv4/IPv6 dual stack support, routing, VLANs, QoS, and the default setting. This can be used (as shown in the video) to enhance the IPv6 capabilities of your 3750s and I have also used this command to enable dual stack on the Cisco 2960 for use in my CCNA course.
