Dynamic interfaces, also known as VLAN interfaces, are created by users and designed to be analogous to
VLANs for Wireless LAN clients. A controller can support up to 512 dynamic interfaces (VLANs). Each
dynamic interface is individually configured and allows separate communication streams to exist on any or all
of the distribution system ports of the controller. Each dynamic interface controls VLAN and other
communications between controllers and all other network devices, and each acts as a DHCP relay for
wireless clients associated to WLANs mapped to the interface. You can assign dynamic interfaces to
distribution system ports, WLANs, the Layer 2 management interface, and the Layer 3 AP−manager interface.
You can also map the dynamic interface to a backup port.

You can configure zero, one, or multiple dynamic interfaces on a distribution system port. However, all
dynamic interfaces must be on a different VLAN or IP subnet from all other interfaces configured on the port.
If the port is untagged, all dynamic interfaces must be on a different IP subnet from any other interface
configured on the port.

Configuring a dynamic interface with a secondary subnet is not supported.

Cisco recommends using tagged VLANs for dynamic interfaces.

VLANs with WLAN controllers use this model:
