Case Study: Configuring Converged Access with the Cisco Catalyst 3850 Switch
This section explains how to configure the wireless services on the Cisco Catalyst 3850 Switch. The converged
access deployment is explained using a case study that starts with a small branch that grows to a large branch or
medium campus deployment.
Configuring the Small Branch Deployment
One Cisco Catalyst 3850 Switch forms the access layer. The distribution in this example is made of the Cisco
Catalyst 4500E Supervisor 7-E systems in virtual switching system (VSS) configuration. It is a multilayer network
design where the L3 switched virtual interfaces (SVIs) for L2 VLANs on the access are defined on the VSS system.
The Cisco Catalyst 3850 Switch connects to the VSS through an L2 port channel configured as an 802.1Q trunk
carrying all the VLANs. Three VLANs are used: VLAN 501 for wired clients, VLAN 500 for wireless clients, and
VLAN 601 for switch and wireless management. The access points connect directly to the switch. (See Figure 13).

Use these commands to enable wireless termination on the Cisco Catalyst 3850 Switch:
The ap cdp command enables CDP process on the Cisco access points connected to the Cisco Catalyst 3850
Switch. The wireless management interface command is used to source the access point CAPWAP and other
CAPWAP mobility tunnels. The wireless mobility controller command enables the switch to act as the mobility
controller role for the converged access deployment. This command requires a reload of the switch. Save the
configuration and reload the switch.
