The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release.

The following are restrictions when using SDM templates:
The LAN Base routing template prevents other features from using the memory allocated to unicast routing. Routing must be enabled on your switch before you can use the routing template.
For more information about homogeneous and mixed stacks, see the Catalyst 2960-X Switch Stacking Configuration Guide.
After you change the template and 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 becomes active after a reload.

All stack members use the same SDM template that is stored on the stack master. When a new switch is added to a stack, as with the switch configuration and VLAN database files, the SDM configuration that is stored on the stack master overrides the template configured on an individual switch.
Version-mismatch (VM) mode has priority over SDM-mismatch mode. If a VM mode condition and an SDM-mismatch mode exist, the switch stack first attempts to resolve the VM-mode condition. You can use the show switch privileged EXEC command to see if any stack members are in SDM-mismatch mode.
1. configure terminal
2. sdm prefer { default | lanbase-default | lanbase-routing }
3. end
4. reload
This is an example output showing the default template information.
Switch# show sdm prefer default "default" template: The selected template optimizes the resources in the switch to support this level of features for 0 routed interfaces and 255 VLANs. number of unicast mac addresses: 8K number of IPv4 IGMP groups + multicast routes: 0.375k number of IPv4 unicast routes: 0 number of IPv6 multicast groups: 0.25K number of directly-connected IPv6 addresses: 0.25K number of indirect IPv6 unicast routes: 32 number of IPv4 policy based routing aces: 0 number of IPv4/MAC qos aces: 0.375k number of IPv4/MAC security aces: 0.375k number of IPv6 policy based routing aces: 0 number of IPv6 qos aces: 60 number of IPv6 security aces: 0.125k Switch#
This is an example output showing the LAN Base default template information.
Switch# show sdm prefer lanbase-default "lanbase-default" template: The selected template optimizes the resources in the switch to support this level of features for 0 routed interfaces and 1024 VLANs. number of unicast mac addresses: 16K number of IPv4 IGMP groups + multicast routes: 1K number of IPv4 unicast routes: 3K number of directly-connected IPv4 hosts: 2K number of indirect IPv4 routes: 1K number of IPv6 multicast groups: 1K number of directly-connected IPv6 addresses: 2K number of indirect IPv6 unicast routes: 1K number of IPv4 policy based routing aces: 0 number of IPv4/MAC qos aces: 0.5K number of IPv4/MAC security aces: 0.625k number of IPv6 policy based routing aces: 0 number of IPv6 qos aces: 0.5K number of IPv6 security aces: 0.625k Switch#
This is an example output showing the LAN Base routing template information.
Switch# show sdm prefer lanbase-routing "lanbase-routing" template: The selected template optimizes the resources in the switch to support this level of features for 0 routed interfaces and 255 VLANs. number of unicast mac addresses: 4K number of IPv4 IGMP groups + multicast routes: 0.375k number of IPv4 unicast routes: 0.875k number of directly-connected IPv4 hosts: 0.875k number of indirect IPv4 routes: 80 number of IPv6 multicast groups: 0.25K number of directly-connected IPv6 addresses: 0.75K number of indirect IPv6 unicast routes: 32 number of IPv4 policy based routing aces: 0 number of IPv4/MAC qos aces: 0.375k number of IPv4/MAC security aces: 0.375k number of IPv6 policy based routing aces: 0 number of IPv6 qos aces: 0.125k number of IPv6 security aces: 0.25K Switch#
This example shows how to configure the VLAN template:
Switch(config)# sdm prefer lanbase-routing Switch(config)# exit Switch# reload Proceed with reload? [confirm]
