Chapter 8 Configuring SDM Templates

You must reload the switch with the dual IPv4 and IPv6 templates for switches running IPv6.
Table 8-2
switches running the IP base or IP services feature set. Template estimations are based on a switch with
8 routed interfaces and 1024 VLANs.
On switches running the LAN base feature set, routing values shown in the templates are not valid.

SDM Templates and Switch Stacks

In a Catalyst 3750-X-only or a mixed hardware switch stack, all stack members must use the same SDM
desktop template that is stored on the stack master. When a new switch is added to a stack, the SDM
configuration that is stored on the stack master overrides the template configured on an individual
switch. For more information about stacking, see
You can use the show switch privileged EXEC command to see if any stack members are in SDM
mismatch mode. This example shows the output from the show switch privileged EXEC command when
an SDM mismatch exists:
