Configuring SDM Templates

Information About 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.

Cisco Catalyst 9200 Series Switches support the following templates:

  • Advanced

  • VLAN

It is recommended that you reload the system as soon as you make a change to the SDM template. 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.

How to Configure SDM Templates

Setting the SDM Template

Follow these steps to use the SDM template to maximize feature usage:

Procedure

  Command or Action Purpose

Step 1

enable

Example:


Device> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2

configure terminal

Example:


Device# configure terminal

Enters global configuration mode.

Step 3

sdm prefer {advanced | vlan }

Example:


Device(config)#sdm prefer vlan

Selects an SDM template.

  • advanced —Sets the switch to the advanced template.

  • vlan —Maximizes VLAN configuration on the switch with no routing supported in hardware.

Step 4

end

Example:


Device(config)# end

Returns to privileged EXEC mode.

Step 5

reload

Example:


Device# reload

Reloads the operating system.

After 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.

Monitoring and Maintaining SDM Templates

Verifying SDM Templates

Use the following commands to monitor and maintain SDM templates.

Command Purpose

show sdm prefer

Displays the SDM template in use.


Note

The SDM templates contain only those commands that are defined as part of the templates. If a template enables another related command that is not defined in the template, then this other command will be visible when the show running config command is entered. For example, if the SDM template enables the switchport voice vlan command, then the spanning-tree portfast edge command may also be enabled (although it is not defined on the SDM template).

If the SDM template is removed, then other such related commands are also removed and have to be reconfigured explicitly.

so only half as many entries can be created.
