Chapter 1 Configuring SDM Templates
Understanding the SDM Templates
SDM Templates and Switch Stacks
In only a Catalyst 3750-X or a mixed hardware switch stack, all stack members must use the same SDM
template that is stored on the active switch. When a new switch is added to a stack, the SDM
configuration that is stored on the active switch overrides the template configured on an individual
switch. For more information about stacking, see Chapter 1, “Managing Switch Stacks.”
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:
Switch# show switch
Current
Switch# Role Mac Address Priority State
------------------------------------------------------------
*2 Master 000a.fdfd.0100 5 Ready
4 Member 0003.fd63.9c00 5 SDM Mismatch
This is an example of a syslog message notifying the stack master that a stack member is in SDM
mismatch mode:
2d23h:%STACKMGR-6-SWITCH_ADDED_SDM:Switch 2 has been ADDED to the stack (SDM_MISMATCH)
2d23h:%SDM-6-MISMATCH_ADVISE:
2d23h:%SDM-6-MISMATCH_ADVISE:
2d23h:%SDM-6-MISMATCH_ADVISE:System (#2) is incompatible with the SDM
2d23h:%SDM-6-MISMATCH_ADVISE:template currently running on the stack and
2d23h:%SDM-6-MISMATCH_ADVISE:will not function unless the stack is
2d23h:%SDM-6-MISMATCH_ADVISE:downgraded. Issuing the following commands
2d23h:%SDM-6-MISMATCH_ADVISE:will downgrade the stack to use a smaller
2d23h:%SDM-6-MISMATCH_ADVISE:compatible desktop SDM template:
2d23h:%SDM-6-MISMATCH_ADVISE:
2d23h:%SDM-6-MISMATCH_ADVISE: "sdm prefer vlan desktop"
2d23h:%SDM-6-MISMATCH_ADVISE: "reload"
