The default template is the default Switch Database Management (SDM) desktop template.

SDM Template Configuration Guidelines

Follow these guidelines when selecting and configuring SDM templates:

You must reload the switch for the configuration to take effect.

Use the sdm prefer vlan global configuration command on switches intended for Layer 2 switching with no routing.

When you use the VLAN template, no system resources are reserved for routing entries, and any routing is done through software. This overloads the CPU and severely degrades routing performance.

Do not use the routing template if you do not have routing enabled on your switch. To prevent other features from using the memory allocated to unicast routing in the routing template, use the sdm prefer routing global configuration command.

If you try to configure IPv6 without first selecting a dual IPv4 and IPv6 template, a warning message appears.

Using the dual stack template results in less hardware capacity allowed for each resource, so do not use it if you plan to forward only IPv4 traffic.
