I've a situation where I need to add a new 3750x to a existing stack of 3750. Information as follows :
The new switch is :
SW Version 12.2(55)SE3
SW Image C3750E-UNIVERSALK9-M
The existing switch stack consists of the following switches :
1 WS-C3750-48P 12.2(25)SEE2 C3750-IPSERVICES-M
2 WS-C3750-48P 12.2(25)SEE2 C3750-IPSERVICES-M
3 WS-C3750-48P 12.2(25)SEE2 C3750-IPSERVICES-M
4 WS-C3750G-48TS 12.2(25)SEE2 C3750-IPSERVICES-M
When I tried to stack them together, I get a version mismatch error. Is this because of the difference in SW Image? What are my options next ? My ultimate goal is to make the new switch stack correctly with the exisitng switches.
Usually these are handled by my colleague but he's on vacation.
Is order for the stack to work correctly, you need to have the same exact image in all your switches including the new one.
You currenly have 12.2(25) in the existing switches and 12.2(55) in the new switch. Try to upgrade all you switches to 12.2(55) if you have enough flash in the existing switches. If not you would need to lower the image in the new switch to 12.2(25) (the same as the existing switches).
