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?

The Cisco SSO technology synchronizes the Layer 2/3 and wireless tunnel protocol state machines from Active to Standby stack switch. During Active switch switchover the Standby switch performs graceful-recovery with neighbors without disrupting network topology.

Can the Cisco Catalyst 3850 act as a wired switch?

The Cisco Catalyst 3850 switch can act as a wired switch as well as a converged wired wireless switch.

What management ports are available on the Cisco Catalyst 3850?

The Cisco Catalyst 3850 comes with a 10/100 Ethernet dedicated management port on the backside of the switch right above the console port. This port is in separate VRF called “Mgmt-vrf.” This is to segment the management traffic from the global routing table of the switch.
Can both console ports be used simultaneously?
No. When the USB console is used, the RJ-45 console receives the output of the USB console as well. This design allows the administrator to see when the USB console port is in use. This capability is useful for remote administrators.

Does the Cisco Catalyst 3850 support 802.1ae on downlink ports?

The Cisco Catalyst 3850 is hardware capable for 802.1ae on all ports on the switch. Software support will be available later.
