Stacking WS-C3750X-12S-S and WS-C3750X-48T-L

[Sunil Gajjar]

I have a couple of WS-C3750X-48T-L and a couple of WS-C3750X-12S-S, I want to stack all four of them together into a single stack.

WS-C3750X-12S-S are running c3750e-universalk9-mz.122-58.SE2 whereas WS-C3750X-48T-L are running c3750e-universalk9-mz.122-55.SE3.

I have got a couple of queries as under:

What are the options to achieve putting all these 4 switches into a single stack?

Can the LAN Base switches upgraded to IP Base? If yes, what would be the procedure?

Thanks in advance!

The Cisco Catalyst 3750-X Series Switches with LAN  Base feature set can only stack with other Cisco Catalyst 3750-X Series  LAN Base switches. A mixed stack of LAN Base switch with IP Base or IP  Services features set is not supported.

I have verified it and it is possible by upgrading license on WS-C3750X-48T-L - product number is L-C3750X-48-L-S. It will allow me to upgrade WS-C3750X-48T-L to IP Base so that I can stack them with WS-C3750X-12S-S.

Upgrade the WS-C3750X-48T to the same IOS version as the WS-C3750X-12S.  Make sure that all of the stack members have the same license level.
