Configuring SDM Templates
The Catalyst 2960 and 2960-S switch command reference has command syntax and usage information.
Unless otherwise noted, the term switch refers to a standalone switch and a switch stack.
Note Configuring an SDM template is not required on Catalyst 2960-S switches unless you configure static
routing on the switch. A Catalyst 2960-S switch running the LAN base image uses a default template
that includes maximum resources for all supported features.

Understanding the SDM Templates
Note The SDM template used by Catalyst 2960-S running LAN Lite image is a default templates and is not
configurable. Catalyst 2960-S switches running the LAN base image support only a default template and
the lanbase-routing template.
You can use SDM templates to configure system resources in the Catalyst 2960 switch to optimize
support for specific features, depending on how the switch is used in the network. You can select a
template to provide maximum system usage for some functions or use the default template to balance
resources.
To allocate ternary content addressable memory (TCAM) resources for different usages, the switch SDM
templates prioritize system resources to optimize support for certain features. You can select SDM
templates to optimize these features on the Catalyst 2960 switch:
• Default—The default template gives balance to all functions.
• Dual—The dual IPv4 and IPv6 template allows the switch to be used in dual stack environments
(supporting both IPv4 and IPv6). Using the dual stack templates results in less TCAM capacity
allowed for each resource. Do not use them if you plan to forward only IPv4 traffic.
Note The dual IPv4 and IPv6 template is not supported on Catalyst 2960 switches running the LAN
Lite image or on Catalyst 2960-S switches.
