Configuring SDM Templates
This chapter describes how to configure the Switch Database Management (SDM) templates on the
Catalyst 3750-X or 3560-X switch. Unless otherwise noted, the term
switch refers to a Catalyst 3750-X
or 3560-X standalone switch and to a Catalyst 3750-X switch stack.
Note For complete syntax and usage information for the commands used in this chapter, see the command

Understanding the SDM Templates
You can use SDM templates to configure system resources in the 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; for example, use the default template to balance resources,
and use the access template to obtain maximum ACL usage. The switch SDM templates allocate system
hardware resources for different uses.
You can select SDM templates for IP Version 4 (IPv4) to optimize these features on switches running
the IP Base or IP Services feature set:
Note When the switch is running the LAN Base feature set, do not select a routing template ( sdm prefer
routing ). The routing values shown in the templates are not valid on the switch. To configure IPv4 static
routing on switches running the LAN Base feature set, you must use the default template.
• Routing—The routing template maximizes system resources for unicast routing, typically required
for a router or aggregator in the center of a network.
•
VLANs—The VLAN template disables routing and supports the maximum number of unicast MAC
addresses. It would typically be selected for a Layer 2 switch.
• Default—The default template gives balance to all functions.
