Converged Wired and Wireless Access
This workflow explains how to enable the converged access functionality of the switch, and explains how
the switch can operate as the wireless mobility controller (MC) as well as the wireless mobility anchor
(MA) in a small branch deployment.
Wired and wireless features that are enabled in the same platform is referred to as converged access. The
wired plus wireless features are bundled into a single Cisco IOS Software image, which reduces the
number of software images that users have to qualify and certify before enabling them in their network.
Converged access improves wireless bandwidth across the network and the scale of wireless deployment.
For example, a 48-port Catalyst 3850 switch provides 40 Gbps of wireless throughput. This wireless
capacity increases with the number of members in the stack. This ensures that the network will scale
with current wireless bandwidth requirements, as dictated by IEEE 802.11n-based access points and
with future wireless standards such as IEEE 802.11ac.
Prerequisites
Complete the following tasks before proceeding with wireless configuration:
• Switch stack must function in Stateful Switchover (SSO) mode.
• Interface configuration is completed, as explained in the “Access Interface Connectivity” workflow.
• Lightweight access points are used.
• NTP configuration should be present and operational, as explained in the “Global System
Configuration” workflow.
• A wireless site survey should be completed. The site survey identifies the proper placement of
wireless access points for the best coverage. For detailed information about the site survey process
and the tool to use, see the Wireless Site Survey FAQ.
• Complete the QoS workflow.
Restrictions
• AP-count licenses are supported only on IP Base and IP Services licenses. See the Cisco Catalyst
3850 Switch Right-to-Use Licensing Model.
