Configuring Sdm Templates; Understanding The Sdm Templates - Cisco 3750G - Catalyst Integrated Wireless LAN Controller Configuration Manual

Configuring SDM Templates

This chapter describes how to configure the Switch Database Management (SDM) templates on the
Catalyst 3750 switch. Unless otherwise noted, the term switch refers to a standalone switch and a switch
stack.

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 access template to obtain maximum ACL usage.
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 for IP Version 4 (IPv4) to optimize these features:

There are two versions of each template: a desktop template and an aggregator template. The
Catalyst 3750-12S switch can use the larger TCAM size available in the aggregator templates or can use
the standard desktop templates. All other Catalyst 3750 switches support only the desktop templates. If
you do not enter the desktop keyword on an aggregator switch, the aggregator templates are selected.

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.
Access—The access template maximizes system resources for access control lists (ACLs) to
accommodate a large number of ACLs.
