Managing Licenses on a Stack
The SummitStack feature is not licensed separately. You can use the
SummitStack feature with an Edge 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 the Advanced
Edge license and you attempt to add a master-capable node that is using an Edge
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.
