AIR-WLC2125-K9 Overview
Cisco Wireless LAN Controllers work in conjunction with Cisco Aironet access points and the Cisco Wireless Control System (WCS) to provide systemwide wireless LAN functions. As a component of the Cisco Unified Wireless Network, the Cisco 2100 Series enables administrators to securely manage WLANs and mobility services, such as enhanced security, voice, guest access, and location services.
Cisco 2100 Series Wireless LAN Controllers supports up to 6, 12, or 25 access points and up to 256 clients, making it a cost-effective solution for retail, enterprise branches, and small and medium-sized businesses. These controllers come with eight Ethernet ports, two of which can provide power directly to Cisco lightweight access points.
