Features: Advanced QoS, NetFlow, other services for wireless and wired traffic, Layer 3 visibility, and WAN
efficiency.
Benefits: Management simplicity, good availability due to mobility agent/mobility controller redundancy
within the Cisco Catalyst 3850 switch stack, optimized multicast, mobile device onboarding, BYOD and
wireless continuity with either WAN outage or switch failure within the stack. These benefits are also shared
with environments describe next.
Financial services or retail industries with small branch environments are some of the examples of customers that
might consider this deployment model. (See Figure 4.)

Large Branch or Small/Medium Campus Environment
This can be a medium to large remote site such as an entire building or a remote campus. Network reliability is
critical, and scalability also becomes important because there are more end users and devices in this type of
environment. High-quality user experience and productivity gains are top priorities. Converged access can be
implemented by multiple stacks of Cisco Catalyst 3850 switches to support wired and wireless networking needs.
Each Cisco Catalyst 3850 switch stack serves as a wireless mobility agent and mobility controller. This model
supports up to 250 access points and 16,000 wireless clients without requiring a dedicated WLC.
Features: Advanced QoS, NetFlow, other services for wireless and wired traffic, Layer 3 roaming,
VideoStream and optimized multicast, mobile device onboarding, BYOD, and network intelligence.
Benefits: High-quality user experience, excellent availability because of mobility agent/mobility controller
redundancy within the Cisco Catalyst 3850 switch stacks, and wireless continuity to mitigate risks because
of either WAN outage or switch failure within the stack. (See Figure 5.)
