System Management Software Configuration Guide for Cisco IE 2000U and Connected Grid Switches

Configuring SDM Templates

This chapter describes how to configure the Switch Database Management (SDM) templates on the

Cisco Industrial Ethernet 2000U Series (IE 2000U) and Connected Grid Switches, hereafter referred to

as switch. SDM template configuration is supported in both IP Services and LAN Base images.

Note For complete syntax and usage information for the commands used in this chapter, see the command

Information About the SDM Templates

If the switch is running the IP services image, you can use SDM templates to optimize system resources

in the switch to support specific features, depending on how the switch is used in the network. The SDM

templates allocate TCAM resources to support different features. You can use the SDM templates for IP

Version 4 (IPv4) and select the default template to balance system resources or select the layer-2

template to support only Layer 2 features in hardware.

• Layer-2—The layer-2 template maximizes system resources for Layer 2 functionality and does not

support routing. You should use this template when the switch is being used for Layer 2 forwarding.

When you select the layer-2 template on a switch running the IP services image, any routing is done

through software, which overloads the CPU and severely degrades routing performance.
