Cisco Cisco Aironet 1200 Access Point Referencia técnica

Cisco SWAN provides the framework to integrate and extend wired and wireless networks to deliver the 
lowest possible total cost of ownership for companies deploying WLANs. Cisco SWAN extends 
"wireless awareness" into important elements of the network infrastructure, providing the same level of 
security, scalability, reliability, ease of deployment, and management for wireless LANs that 
organizations have come to expect from their wired LANs.

The Cisco SWAN framework addresses two key issues with managing and operating WLANs: fast secure 
WLAN client roaming and radio management. Fast secure roaming allows WLAN clients to move 
association from one access point to another with little or no service disruption. Cisco SWAN radio 
management characterizes the radio transmission environment and responds to the conditions of the 
environment.

The Cisco SWAN framework can be visualized as a layered model. The Cisco SWAN framework layers 
are:

Management Layer

Wireless Domain Services Layer

Infrastructure Access Point Layer

Wireless Client Layer

Access Point-Based 
WDS Architecture

The Access Point-Based WDS architecture is an architecture 
with Layer 2 WLAN control domains, where WDS is hosted 
on Cisco Aironet access points.

Switch-Based WDS 
Architecture

The Switch-Based WDS architecture is an architecture with 
Layer 3 WLAN control domains, where the WDS is hosted on 
the WLSM.

mGRE

Multipoint Generic Route Encapsulation — A tunneling 
encapsulation type defined by IETF RFC that is leveraged by 
the Cisco SWAN framework switch-based WDS solution.

CCKM

Cisco Centralized Key Management — A Cisco- defined 
encryption key management scheme that enables fast secure 
roaming within a WLAN control domain.

802.1X/EAP

802.1X is an IEEE defined mechanism for port access control, 
and extensible authentication protocol (EAP) is an 
authentication protocol defined by IETF RFC. EAP is generic 
enough to be implemented in a number of ways, including 
Cisco LEAP, EAP-FAST, PEAP, EAP-TLS, and EAP-TTLS. 
The combination of 802.1X port access control and EAP 
authentication type is used to secure access to the WLAN.

Cisco LEAP

A Cisco-defined EAP type for secure access to the WLAN

EAP-FAST

A Cisco-defined EAP type for secure access to the WLAN
