Configuring SDM Templates
This chapter describes how to configure the Switch Database Management (SDM) templates on the IE
3000 switch.
Note For complete syntax and usage information for the commands used in this chapter, see the command
reference for this release.

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:
• Default—The default template gives balance to all functions.
• QoS—The QoS template maximizes system resources for quality of service (QoS) access control
entries (ACEs).
• 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.
Table 10-1 lists the approximate numbers of each resource supported in each template.
