Cisco IOS Software Release 12.2(15)XR New Features
IP-Based Wireless Domain Services
IP-based Wireless Domain Services (WDS) enables the access point to be explicitly configured with the IP address of its WDS device. This allows the access point to use a Cisco network infrastructure device running WDS from anywhere in the network.
Layer 3 Mobility Service via Fast Secure Roaming Tunnels
This feature allows an access point to segregate WLAN clients into different mobility groups. Once a client is authenticated according to its mobility group's security policy, all IP traffic from that client is encapsulated using generic routing encapsulation (GRE) and sent to a specific multipoint GRE (mGRE) interface of a Cisco Structured Wireless-Aware Network (SWAN) infrastructure device that supports mobility groups. An access point with Layer 3 Mobility Service provides clients within each mobility group with Layer 3 mobility when used with a Cisco SWAN infrastructure devices supporting Layer 3 mobility. Support for Layer 3 roaming is provided for all Wi-Fi certified client devices. Support for fast secure Layer 3 roaming is provided for Cisco or Cisco Compatible wireless LAN client devices using the Cisco Centralized Key Management (CCKM) protocol.
