Select an SDM template that supports IPv4 and IPv6.

•default—Set the switch to the default template to balance system resources.

•routing—Set the switch to the routing template to support IPv4 and IPv6 routing, including IPv4 policy-based routing.

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

desktop—Supported only on Catalyst 3750-12S aggregator switches to set the switch to one of the desktop templates. If not selected on an aggregator switch, an aggregator template is automatically selected.
