Managing Licenses on a Stack
The SummitStack feature is not licensed separately. You can use the
SummitStack feature with a Base or Premier license.
The rules for licensing are as follows:
- The effective license level of all master-capable nodes must be
the same.
- If you set a license level for the stack, then each node must be
at that license level or higher.
- If you do not set a license level for
the stack, the license level the stack uses is the effective license level of the
node that is elected master at startup.

Note
If the stack is using
a certain license level, and you attempt to add a master-capable node that is
using a lower level license, the node does not become operational. In response
to the
show slot {slot {detail} | detail }
command, the node displays as Failed with a License Mismatch reason.
- Master-capable nodes continuously monitor the effective license
level of the master node.
- Nodes with higher license levels than other nodes can be
restricted to operate at a lower or effective license level.
