To allocate ternary content addressable memory (TCAM) resources for different usages, the switch SDM templates prioritize system resources to optimize support for certain features. You can select SDM templates to optimize these features:
* Access — The access template maximizes system resources for access control lists (ACLs) to accommodate a large number of ACLs.
* Default — The default template gives balance to all functions.
* Routing — The routing template maximizes system resources for Ipv4 unicast routing, typically required for a router or aggregator in the center of a network.
* VLANs — The VLAN template disables routing and supports the maximum number of unicast MAC addresses. It would typically be selected for a Layer 2 switch.
