3850 stackable with different License Levels?

[Kevin Smith]

We will be decommissioning a 3750 that is uplinked to a 3850-48 port and will be connecting a 3850-24 port in full stack-wise and stack-power High availability mode………now it will have the same IOS but the License Level will be different….so my question is will the two switches become stackable with different License Levels?

Based on the FAQ that is not supported:

You find the FAQ on http://www.cisco.com/go/3850 -> FAQ

Q. What are the license requirements for a Cisco Catalyst 3850 switch stack?

A. In a Cisco Catalyst 3850 stack, all switches should be at the same image-based license (IP Services/IPBase/LAN Base) level. The active switch license level is considered as the reference, and the member switch licenses are compared against it. If there is a mismatch, the active switch with the syslog message “ license mismatch error” indicates that the stacking was unsuccessful.

Q. How is a “ license mismatch error” fixed in a Cisco Catalyst 3850 stack?

A. The license level of the mismatch stack member switch can be changed with the license right-to-use activate <license> all acceptEULA CLI command (entire stack should have the same wired license level) and reloaded from the active switch console. This will enable the member switch to join the stack successfully. The customer has to purchase a license before moving to a specific license level.
