sdm prefer
Use the sdm prefer global configuration command on the switch stack or on a standalone switch to
configure the template used in Switch Database Management (SDM) resource allocation. 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. Use the no form of this command to return
to the default template.
sdm prefer {access | default | dual-ipv4-and-ipv6 {default | routing | vlan} | routing | vlan}
no sdm prefer
Note Although visible in the command-line help, the ipe keyword is not supported. The routing keywords are
not supported on switched running the LAN base feature set.

including IPv4 policy-based routing.
Note The routing keyword is not supported on switches running the LAN

resources for use as a Layer 2 switch with no routing.
