White Paper

●

Distributed intelligent services with Flexible NetFlow on all ports, hardware capability for TrustSec and

MediaNet, and ease of operations using Cisco

Catalyst

Smart Operations.

●

Foundation for Cisco Open Network Environment enabled by the new ASIC with programmability and

investment protection.

The new Cisco Catalyst 3850 switch also provides enhanced radio resource management (RRM) capabilities,

which include neighbor discovery; noise, interference, load, and coverage measurements; use of the neighbor list;

and rogue containment and detection. Additional Cisco advanced radio frequency (RF) technologies include Cisco

CleanAir

, ClientLink 2.0, and VideoStream. CleanAir uses silicon-level intelligence to create a spectrum-aware

and self-optimizing wireless network that mitigates RF interference. VideoStream provides superior and consistent

performance of streaming video over wireless by enforcing video priority levels, controlling resource reservation,

and delivering reliable multicast.

In addition to the ability to terminate wireless data tunnels on the Cisco Catalyst 3850 switch and to apply policies

and Flexible NetFlow within hardware, irrespective of the number of policies applied, the QoS entries, the access-

control list (ACL), or the number of clients connected, the Cisco Catalyst 3850 switch with its built-in wireless

controller functionality continues to provide line-rate throughput. (See Figure 1.)

Additional Deployment Modes

In addition to converged access, Cisco also provides other deployment modes of the wireless infrastructure to

support the flexibility required to best match the network with the business requirements.

●

Autonomous: This is a deployment mode in which no wireless controllers are used. It is traditionally used

in small customer deployments. Wireless access points provide RF management, and they work directly

with ISE and Prime infrastructure to meet policy and network management requirements.
