The Cisco® Catalyst® 3850 Series is the next generation of enterprise-class stackable access-layer switches that provide full convergence between wired and wireless on a single platform. Cisco's new Unified Access Data Plane (UADP) application-specific integrated circuit (ASIC) powers the switch and enables uniform wired plus wireless policy enforcement, application visibility, and application optimization. This convergence is built on the resilience of the new and improved Cisco StackWise-480. The Cisco Catalyst 3850 Series Switches support full IEEE 802.3at Power over Ethernet Plus (PoE+), Cisco Universal Power over Ethernet (UPOE), modular and field-replaceable network modules, redundant fans, and power supplies.
Integrated wireless controller capability with:
Up to 40G of wireless capacity per switch (48 port models)
Up to 50 access points (APs) and 2000 wireless clients support on each switching entity (switch or stack)
24 and 48 10/100/1000 data and Power over Ethernet Plus (PoE+) models with Energy Efficient Ethernet (EEE)
Cisco StackWise®-480 technology provides scalability and resiliency with 480 Gbps of stack throughput
Cisco StackPower!22 technology provides power stacking among stack members for power redundancy
Three optional uplink modules with 4 x Gigabit Ethernet, 2 x 10 Gigabit Ethernet or 4 x 10 Gigabit Ethernet ports
Dual redundant, modular power supplies and three modular fans providing redundancy
Full IEEE 802.3at (PoE+) with 30W power on all ports in 1 rack unit (RU) form factor
Cisco Universal Power over Ethernet (UPOE) which delivers up to 60W per port over standard cabling infrastructure
Software support for IPv4 and IPv6 routing, Multicast routing, modular quality of service (QoS), Flexible NetFlow (FnF) Version 9, and enhanced security features
Single Universal IOS image across all license levels, providing an easy upgrade path for software features
Enhanced limited lifetime warranty (E-LLW) with next business day (NBD) advance hardware replacement and 90-day access to Cisco Technical Assistance Center (TAC) support
Converged Wired plus Wireless Access
Mobility agent (MA): This is the default mode in which the Cisco Catalyst 3850 switch ships. In this mode the switch is capable of terminating the CAPWAP tunnels from the access points and providing wireless connectivity to wireless clients. Maintaining wireless client databases and configuring and enforcing security and QoS policies for wireless clients and access points can be enforced in this mode. No additional license on top of IP Base is required to operate in the mobility agent mode.
Mobility controller (MC): In this mode, the Cisco Catalyst 3850 switch can perform all the mobility agent tasks in addition to mobility coordination, radio resource management (RRM), and Cisco CleanAir®coordination within a mobility subdomain. The mobility controller mode can be enabled on the switch CLI. IP Base license level is required when the Cisco Catalyst 3850 switch is acting as the mobility controller. A centrally located Cisco 5508 Wireless LAN Controller (WLC 5508), Cisco Wireless Services Module 2 (WiSM2) (when running AireOS Version 7.3), and Wireless LAN Controller 5760 can also perform this role for larger deployments.
