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.
These templates are supported on your device:
-
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.

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.
