CNT1512 3/2/2023 Chapter 07 - Configuring Access Points Assignment 1. Describe the three types of APs found in controller-based architectures and compare them to the autonomous AP architecture. The three main types of APs found in controller-based architecture are: Lightweight APs: limited functionality, no management or configuration functions; benefit of decreased ownership cost. Fewer functions than autonomous AP architecture, but less costly. Mesh APs: a mesh AP is almost entirely wireless, as only one mesh AP must be physically connected to the wired network. The rest of the mesh APs do not need to be connected, and are able to communicate through each other. Captive Portal APs: involve the use of a web browser for logging in, reading and accepting policies, and providing other information to the user. Captive Portal APs are typically found when accessing a public WLAN. 2. How are wireless LAN controllers similar to network switches? Wireless LAN controllers are very similar to network switches, so much so that they are sometimes called wireless switches. Like network switches, WLAN controllers monitor what devices are connected to the network, and they allow for devices within the network to communicate with each other. 3. How can SNMP be used to monitor network devices? Simple Network Management Protocol (SNMP) can be used to monitor network devices through the use of SNMP agents and an SNMP manager. Data is gathered by SNMP from all devices on the network. Commands can manually be sent to gather specific information, and SNMP metrics can be viewed as well. SNMP tools are essential for monitoring and maintaining a vast array of devices on the network with relative ease. 4. What is a wireless mesh network? A Wireless Mesh Network, or WMN, involves several mesh APs communicating amongst each other. Each mesh AP does not need to individually be connected to the wired network; rather, only one of the APs within the WMN must be physically connected to the wired network. 5. Compare Single Channel Architecture against Multiple Channel Architecture. Single-channel and Multiple-channel are two architecture models for WLANs: Single-channel Architecture has all APs using the same channel. This allows for easier setup and smoother handoffs, although issues with cochannel interference may prove to be a problem unless mitigation techniques are employed. Multiple-channel Architecture has APs in the network using more than one channel. This type of architecture is more difficult to deploy than single-channel, yet due to the use of multiple channels, cochannel interference is less of an issue.
