Cisco Three-Layer Hierarchical Model
Providing connectivity between wireless and wired networks to transport data is the primary purpose of Cisco Wireless Architecture and AP modes. Many wireless clients can be connected at once with autonomous AP architecture, and the network functions like a LAN. The Central Access Point, which controls all wireless networks and devices, is provided by the autonomous AP design. Data may be transported between wireless and wired networks thanks to the central access point’s wireless and wired capabilities. The process of encryption and decryption takes place when data is transmitted. The Core layer, Distribution Layer, and Access Layer comprise Cisco’s proprietary three-layer design. An upgraded version of the Cisco three-layer design is the Cisco Wireless Architecture and AP modes. See the graphic below for an explanation of the three-layer hierarchical architecture used by Cisco.
Basic service sets also referred to as BSSs, are offered by the autonomous AP architecture of Cisco Wireless Architecture. In the access layer of Cisco’s three-layer hierarchical architecture, autonomous APs link wireless service set identifiers (SSIDs) with wired virtual LANs. As indicated in the below diagram, a network can use 100 or 1000 APs to offer connectivity to the customers.
The fastest and easiest method for data transfer across wireless and wired networks is used by an Autonomous AP architecture of Cisco Wireless Architecture and AP modes. The access point serves as a bridge between the wired and wireless networks. A device linked to an AP wireless network can send data to another wirelessly connected device without using the wired network. The trunk mode port connects to the core switch and access layer switches in the above image to transport data between VLANs. Each autonomous AP is allocated a fixed IP address for remote management and setup. The primary parameters that must be configured are SSIDs, VLANs, Channel and transmission power, and so on.
Each autonomous AP is necessary to communicate in order to exchange data and maintain VLANs. All AP SSIDs and their VLANs must be extended to layer 2 in order for all VLANs to communicate with the wired network.
Cisco Wireless Architecture and AP Modes
Cisco Wireless Architecture and AP modes connect a wireless network to a wired network to safely transfer data. Cisco Wireless Architecture and AP modes are classified into three categories:
- Autonomous AP architecture
- Cloud-based AP architecture
- Split MAC AP architecture.
