usage:
After the system reboots, you can use the show sdm prefer privileged EXEC command to verify the new
template configuration. If you enter the show sdm prefer command before you enter the reload
privileged EXEC command, the show sdm prefer command shows the template currently in use and the
template that will become active after a reload.

switch to the default desktop template. (Use the no sdm prefer
command to set a desktop switch to the default desktop template
or to set an aggregator switch to the default aggregator template.)
• dual-ipv4-and-ipv6—Select a template that supports both IPv4
and IPv6 routing.
–
