Hi


Is it possible to have a WS-C3750G-12S-S and a WS-C3750X-24T-L in the same stack, if so do they need to both be running the same software version/IOS.


Thanks in advance.


Gavin

If you have a 3750X-24T, your entire stack should be running a minimum of 12.2(53)SE1.  Anything less and the 3750X will not join the stack and the stack won't even know what a "3750X" is.

Hi,


Yes it is possible to have both these switches in stack. One more important thing to note is that the license should be same on both the switches.


3750x switch supports three software feature sets: Lanbase, ipservers, ipbase


Show license detail output from each switch will tell you with what license exactly the switch is running.


Hope this helps


Cheers

Hi


I Managed to stack 3570 X with 3750 G this weekend.


3750 X running IOS

C3750E-UNIVERSALK9-M

3750G running IOS

C3750-IPSERVICESK9-M


Switch Ports Model              SW Version            SW Image                

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

     1 18    WS-C3750X-12S      12.2(58)SE2           C3750E-UNIVERSALK9-M    

     2 18    WS-C3750X-12S      12.2(58)SE2           C3750E-UNIVERSALK9-M    

*    3 52    WS-C3750G-48TS     12.2(58)SE2           C3750-IPSERVICESK9-M    

     4 52    WS-C3750G-48TS     12.2(58)SE2           C3750-IPSERVICESK9-M    


Seems all you need is the SW version to match.

Hi

No this will not work

The Lan base will only stack with other Lan base switches.

You can not mix lan base and ipbase/ip services


it does not matter if the software is the same version or not.

They will not stack with eachother.


IF you update the Lan base license key to an ip base then it will stack with your switch if they have the same software version.


Good luck
