sdm prefer

To configure the template used in Switch Database Management (SDM) resource allocation, use the sdm
prefer command in global configuration mode. You can use a template to allocate system resources to
best support the features being used in your application. Use a template to provide maximum system
usage for unicast routing or for VLAN configuration or to select the dual IPv4 and IPv6 template to
support IPv6 forwarding. To return to the default template, use the no form of this command.
Although visible in the command-line help, the ipe keyword is not supported. The routing keywords are
Note
not supported on switched running the LAN base feature set.

template if you have a large number of ACLs.
Gives balance to all functions.
Select a template that supports both IPv4 and IPv6 routing.
• default—Provide balance to IPv4 and IPv6 functionality.
routing—Provide maximum system usage for IPv4 and IPv6 routing,
•
including IPv4 policy-based routing.
Note
vlan—Provide maximum system usage for IPv4 and IPv6 VLANs.
•
Allows more entries for IPv4 and IPv6 summary or indirect routes, and fewer
entries for IPv4 and IPv6 policy-based routing, QoS, and ACLs.
Provides maximum system usage for unicast routing. You would typically use
this template for a router or aggregator in the middle of a network.
This keyword is not supported on switches running the LAN base feature set.
Provides maximum system usage for VLANs. This template maximizes system
resources for use as a Layer 2 switch with no routing.
