What is a Cisco Lightweight Access Point (LAP)?
A. The Cisco LAP is part of the Cisco Unified Wireless Network architecture. A LAP is an AP that is designed to be connected to a wireless LAN (WLAN) controller (WLC). The LAP provides dual band support for IEEE 802.11a, 802.11b, and 802.11g and simultaneous air monitoring for dynamic, real-time radio frequency (RF) management. In addition, Cisco LAPs handle time-sensitive functions, such as Layer 2 encryption, that enable Cisco WLANs to securely support voice, video, and data applications. APs are “lightweight,” which means that they cannot act independently of a wireless LAN controller (WLC). The WLC manages the AP configurations and firmware. The APs are “zero touch” deployed, and individual configuration of APs is not necessary. The APs are also lightweight in the sense that they handle only real-time MAC functionality. The APs leave all the non-real-time MAC functionality to be processed by the WLC. This architecture is referred to as the “split MAC” architecture.
