As far as I know there is no problem in combining different models of 3750 in the stack so long as they are running the same code and using the same template.

Hi Richard,


It should work fine just take care of one small configuration.


The Cisco Catalyst 3750 series switches use Switch Database Management (SDM) templates to optimize the system resources for specific features dependent on how the switch is used in the network. There are two versions of the SDM templates: Desktop and Aggregator. The 3750-12S switch alone supports both templates. All other model switches of the 3750 series support only the Desktop version.


When a Cisco Catalyst 3750 switch stack consists of 3750-12S and other models, make sure to use only the Desktop SDM template


This is an output from the show switch command when an SDM mismatch exists:


3750-Stk# show switch

Current

Switch# Role Mac Address Priority State

------------------------------------------------------------

*2 Master 000a.fdfd.0100 5 Ready

4 Member 0003.fd63.9c00 5 SDM Mismatch



To change the SDM template on a 3750-12S to Desktop version, complete these steps:


3750-Stk# conf t

3750-Stk(config)# sdm prefer routing desktop
