sdm prefer
Use the sdm prefer global configuration command 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 VLAN configuration or to select the dual IPv4 and IPv6 template to support IPv6 host. Use the no
form of this command to return to the default template.

Usage Guidelines
You must reload the switch for the configuration to take effect. 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.
Use the no sdm prefer command to set the switch to the default template.
The access template maximizes system resources for access control lists (ACLs) as required to
accommodate a large number of ACLs.
The default templates balances the use of system resources.
Do not use the ipv4-and-ipv6 templates if you do not plan to enable IPv6 on the switch. Entering the
sdm prefer ipv4-and-ipv6 {default | vlan} global configuration command divides resources between
IPv4 and IPv6, limiting those allocated to IPv4 forwarding.
