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.
