The rows in the tables represent approximate hardware boundaries set when a template is selected. If a
section of a hardware resource is full, all processing overflow is sent to the CPU, seriously impacting
switch performance.

SDM Templates and Switch Stacks

Note Stacking is supported only on Catalyst 2960-S switches running the LAN base image.
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. 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:
