This chapter describes how to configure the Switch Database Management (SDM) templates on the
Catalyst 2960 switch.
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release.
This chapter consists of these sections:

Understanding the SDM Templates
You can use the 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 or to use the default template to balance resources.
To allocate TCAM resources for different usages, the SDM templates prioritize system resources to
optimize support for certain features. You can select SDM templates to optimize these features:
• QoS—The QoS template maximizes system resources for quality of service (QoS) access control
entries (ACEs).
• Default—The default template gives balance to all functions.
Table 7-1 lists the approximate numbers of each resource supported in each template.
