How many Cisco Catalyst 3850 switches can make up a Cisco StackPower stack?

Up to four switches can become part of the same Cisco StackPower stack in a ring topology.

What are the different types of licenses in the Cisco Catalyst 3850?

There are two main types of Cisco Catalyst 3850 license: permanent RTU license and evaluation RTU license. These are available for both image-based licensing (IP Base or IP Services) and AP count licensing. A permanent RTU license is a paid license, with no expiration date. The universal Cisco IOS XE Softwarebased images have all three license levels: LAN Base, IP Base, and IP Services. RTU CLI commands enable the switch license to be moved between different license levels. An evaluation RTU license allows the customers to evaluate image-based and/or AP count license for 90 days at no cost.

What is SSO technology?
