This document introduces the Cisco 8500 Wireless LAN Controller (WLC), and provides general guidelines for its deployment. The purpose of this document is to: • Provide an overview of the Cisco 8500 WLC, and its deployment within the Cisco Unified Architecture. •...
Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions. Product Overview In Cisco Unified Architecture, a wireless access point (AP) is deployed in one of three major modes in order to serve wireless clients: • Local mode − A Local mode AP tunnels all traffic to the Controller (via CAPWAP), where the Controller handles tagging the packets and placing them on the wired network.

Both the Cisco 5500 Series Controller and the WiSM2 Controller support all modes of AP operation scaling up to 500 and 1000 APs respectively, and 7000 and 15,000 wireless clients respectively. The explosion of mobile clients in enterprise empowered by bring your own device (BYOD), the deployment of wireless in mission−critical applications, and the adoption of Wi−Fi in service provider networks enabling new business...

Look and Feel of the Cisco 8500 Controller The Cisco 8500 Controller enables console redirect by default with baud rate 9600 simulating a VT100 terminal with no flow control. The 8500 Controller has the same boot sequence as existing controller platforms.

The GUI also remains the same as previous controllers.
Highlighted Features in the Cisco 8500 Controller Scalability The Cisco 8500 Series WLC provides Service−Provider−class scalability in a small 1RU form factor. It allows Service Providers to consolidate multiple controllers and reduce operational costs with a single point of control and management for up to 64,000 clients distributed over 4096 VLANs and 6000 APs.
New Licensing Model Release 7.3 also introduces a new Right to Use (RTU) licensing model to the Cisco Flex 7500 and Cisco 8500 Series Controllers. This is an Honor−based licensing scheme that allows AP licenses to be enabled on supported controllers with End User License Agreement (EULA) acceptance The RTU license scheme simplifies addition, deletion, or the transfer of AP adder licenses in the field by eliminating the need for an additional step, additional tools, or access to Cisco.com for PAK license or return materials authorization...
Other device on the network (defined as CN) will be able to reach the wireless client (MN) via its home address through the LMA, which is advertising the reachability for the MN prefix to the CN. For more information on the PMIPv6 Seamless IP Mobility feature, refer to Cisco Wireless Proxy Mobile IPv6 Configuration Guide.

Note: The Passpoint features are available in software release 7.3 for all controller platforms and CAPWAP APs which are capable of running the 7.2 release (except the Office Extend AP600). For more information on configuring these features, refer to the Cisco Wireless LAN Controller Configuration Guide, Release 7.3.
4k VLAN Support at the Controller In order to Address Service Providers scalability requirements, the 7.3 software release extends the number of supported VLANs to 4096. This enables location−based service per Interface/VLAN as the number of maximum interfaces has also been increased from 512 to 4096 (4095 + management interface) and associated VLANs.
Other Important Service Provider Oriented Features These other important Service Provider oriented features were introduced in the Cisco WLCs with the 7.3 code: • Central DHCP for FlexConnect local switching • VLAN Tagging on CAPWAP management (no CAPWAP restriction to native VLAN) •...
Multicast Multicast support is enabled in the Cisco 8500 Controller, and its operation is comparable to that of the Cisco 5500 Series Controllers, but with these restrictions: If all APs on the 8500 Controller are configured in Local mode, Multicast−Multicast will be the default mode and all features are supported (for example, VideoStream).
Note: Multicast−Unicast is required for IPv6 operation on FlexConnect APs (for RA and NS packet delivery). Inter−Platform Mobility In most networks, support for heterogeneous Wireless Controllers in a mobility group is usually required. These can be instances of upgrade, migration, or backup with such a heterogeneous configuration. In these cases, the number of supported Fast Secure Roaming (FSR) clients should be considered in the network design.
