Configuring SDM Templates
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

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 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:
• 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.
• Dual—The dual IPv4 and IPv6 Switch Database Management (SDM) template enables a dual stack
environment.
Table 7-1 lists the approximate numbers of each resource supported in each template.

IPv4 IGMP groups 256 256 256
