    A full-featured command-line interface (CLI) can be used to configure and monitor individual Cisco Wireless LAN Controllers. See Chapter The Cisco Wireless Control System (WCS), which you use to configure and monitor one or more • Cisco Wireless LAN Controllers and associated access points. WCS has tools to facilitate large-system monitoring and control.

  • Page 31: Single-controller Deployments

    Chapter 1 Overview Cisco Unified Wireless Network Solution Overview Figure 1-1 Cisco UWN Solution Components Single-Controller Deployments A standalone controller can support lightweight access points across multiple floors and buildings simultaneously, and supports the following features: • Autodetecting and autoconfiguring lightweight access points as they are added to the network.

  • Page 32: Multiple-controller Deployments

    Multiple-Controller Deployments Each controller can support lightweight access points across multiple floors and buildings simultaneously. However, full functionality of the Cisco Wireless LAN Solution is realized when it includes multiple controllers. A multiple-controller system has the following additional features: Autodetecting and autoconfiguring RF parameters as the controllers are added to the network.

    Cisco Wireless Control System (WCS) to provide system-wide wireless LAN functions. Each 2100 series controller controls up to 6, 12, or 25 lightweight access points for multi-controller architectures typical of enterprise branch deployments. It may also be used for single controller deployments for small and medium-sized environments.

  • Page 37: Catalyst 6500 Series Wireless Services Module

    Without any other service module installed, the Catalyst 6509 switch chassis can support up to seven Note Cisco WiSMs, and the Catalyst 6506 with a Supervisor 720 can support up to four Cisco WiSMs. If one or more service modules are installed, the chassis can support up to a maximum of four service modules (WiSMs included).

    Access points subscribe to the CAPWAP multicast group using IGMP. • Cisco 1100, 1130, 1200, 1230, and 1240 access points use IGMP versions 1, 2, and 3. • Access points in monitor mode, sniffer mode, or rogue detector mode do not join the CAPWAP multicast group address.
