Finding Feature Information
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required.
Information About Configuring SDM Templates
SDM Templates
You can use SDM templates to configure system resources to optimize support for specific features, depending on how your device is used in the network. You can select a template to provide maximum system usage for some functions.
Advanced—The advanced template is available on all supported images for this release. It maximizes system resources for features like netflow, multicast groups, security ACEs, QoS ACEs, and so on.
VLAN—The VLAN template is available only on the LAN Base license. The VLAN template disables routing and supports the maximum number of unicast MAC addresses. It would typically be selected for a Layer 2 device.
After you change the template and the system reboots, you can use the show sdm prefer privileged EXEC command to verify the new template configuration. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.
The default is the advanced template.

 Note | When the switch is used as a Wireless Mobility Agent, the only template allowed is the advanced template. |
The tables represent approximate hardware boundaries set when a template is selected. If a section of a hardware resource is full, all processing overflow is sent to the CPU, seriously impacting switch performance.
SDM Templates and Switch Stacks
In a switch stack, all stack members must use the same SDM template that is stored on the active switch. When a new switch is added to a stack, the SDM configuration that is stored on the active switch overrides the template configured on an individual switch.

DETAILED STEPS
Monitoring and Maintaining SDM Templates
| Command | Purpose |
|---|---|
show sdm prefer |
Displays the SDM template in use. |
reload |
Reloads the switch to activate the newly configured SDM template. |
no sdm prefer |
Sets the default SDM template. |
Configuration Examples for Configuring SDM Templates
Examples: Configuring SDM Templates
This example shows how to configure the VLAN template:
SwitchControllerDevice(config)# sdm prefer vlan SwitchControllerDevice(config)# exit SwitchControllerDevice# reload Proceed with reload? [confirm]
Examples: Displaying SDM Templates
This is an example output showing the advanced template information:
SwitchControllerDevice# show sdm prefer Showing SDM Template Info This is the Advanced template. Number of VLANs: 4094 Unicast MAC addresses: 32768 Overflow Unicast MAC addresses: 512 IGMP and Multicast groups: 8192 Overflow IGMP and Multicast groups: 512 Directly connected routes: 32768 Indirect routes: 8192 Security Access Control Entries: 3072 QoS Access Control Entries: 2816 Policy Based Routing ACEs: 1024 Netflow ACEs: 1024 Input Microflow policer ACEs: 256 Output Microflow policer ACEs: 256 Flow SPAN ACEs: 256 Tunnels: 256 Control Plane Entries: 512 Input Netflow flows: 8192 Output Netflow flows: 16384 These numbers are typical for L2 and IPv4 features. Some features such as IPv6, use up double the entry size; so only half as many entries can be created. SwitchControllerDevice#
This is an example output showing the VLAN template information:
SwitchControllerDevice# show sdm prefer vlan Showing SDM Template Info This is the VLAN template for a typical Layer 2 network.
