Chapter 1 Overview
Cisco Wireless LAN Solution Overview
Figure 1-1 shows the Cisco Wireless LAN Solution components, which can be simultaneously deployed
across multiple floors and buildings.
Figure 1-1 Cisco WLAN Solution Components
Single-Controller Deployments
A standalone Cisco Wireless LAN 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.
Full control of lightweight access points.
Full control of up to 16 lightweight access point wireless LAN (SSID) policies.
Lightweight access points connect to controllers through the network. The network equipment may
or may not provide Power over Ethernet to the access points.
Note that some Cisco Wireless LAN Controllers use redundant Gigabit Ethernet connections to bypass
single network failures. At any given time one of the redundant Gigabit Ethernet connections is active
and the other is passive. Upon a network failure, the active connection becomes passive, and the passive
connection becomes active.
Note Some controllers can connect through multiple physical ports to multiple subnets in the network. This
feature can be helpful when Cisco WLAN Solution operators want to confine multiple VLANs to
separate subnets.
Figure 1-2 shows a typical single-controller deployment.
