What You Should Pay Attention to Cisco Aironet Access Point While Purchasing

Executive Summary

Access points are critical elements of the Cisco Unified Wireless Network. Cisco single- and dual band access points are designed for offices and similar environments, challenging RF environments, and the outdoors. The devices are available in two versions: unified or autonomous. Unified access points operate with the Lightweight Access Point Protocol (LWAPP) and work in conjunction with Cisco wireless LAN controllers and the Wireless Control System (WCS).

Autonomous access points are based on Cisco IOS Software and may optionally operate with the CiscoWorks Wireless LAN Solution Engine (WLSE). Autonomous access points, along with the WLSE, deliver a core set of features and may be field-upgraded to take advantage of the full benefits of the Cisco Unified Wireless Network as requirements evolve.

To make the best choices for their particular applications, customers need to understand the features and benefits of the different Cisco Aironet access points. This solution overview details the capabilities of each of the devices in the Cisco Aironet Family of wireless access points.

Management Paradigm

As wireless LANs become increasingly mission-critical and evolve in terms of scale and capabilities, the way the wireless deployment is managed must evolve as well. Because each customer and each deployment is unique, Cisco provides differing feature sets and differing paradigms to address these customer-specific requirements.

Cisco provides a core feature set that includes autonomous access points and the CiscoWorks WLSE management appliance. The core feature set provides a base set of capabilities that are required for enterprise deployments. Core features include secure connectivity through support for 802.11i Wi-Fi Protected Access 2 (WPA2), fast and secure Layer 2 roaming, and interfaces to a variety of third-party applications and products. Most Cisco access points are available in versions designed for autonomous operation. These devices may be upgraded in the field to lightweight mode, thereby providing customers with a smooth path from core to unified features.

The Cisco unified feature set is delivered by lightweight access points, wireless LAN controllers, and the Wireless Control System (WCS) management solution. The unified feature set represents the most comprehensive set of capabilities in the industry, including guest access, wireless intrusion detection and intrusion prevention, scalable Layer 3 mobility, and location services. Most Cisco Aironet access points are available in versions designed for lightweight operation.

Deployment Environments

Wireless LANs are becoming commonplace in numerous environments, including offices, schools, factories, warehouses, and even the outdoors. At the same time, the wireless industry is evolving from lower-capacity, single-band devices to high-capacity, dual-band solutions. The Cisco Aironet

Family of access points meets these various application requirements by providing:

Single- and dual-band access points

Devices designed for indoor and outdoor deployments

A consistent hardware feature set and predictable RF performance for deployment across the enterprise

As WLAN deployment expands into more applications and installation scenarios, a diverse line of access points is required to meet the associated capacity, coverage, and environmental requirements. The Cisco product line includes access points designed for offices and similar facilities, such as hospitals and retail environments, challenging RF environments like factories and warehouses, and the outdoors. These devices can be installed on desktops, on walls, on ceilings, above ceilings, and on top of poles.

While application requirements may vary, Cisco understands that all enterprise customers require uncompromised network security, scalable manageability, and an evolving set of network services. That’s why all Cisco Aironet access points support the Cisco Unified Wireless Network, a framework for wired and wireless integration that delivers the security, manageability, and services that enterprises have come to expect from Cisco on both wired and wireless networks.

Solution

Addressing Feature Requirements

As wireless LAN usage has evolved from basic transport for largely transactional applications, so have the feature expectations of wireless LAN users and administrators. This change has come about on a segment-by-segment, customer-by-customer basis. It is critical for Cisco to provide differing feature sets to best fit differing customer requirements. Given that customer requirements can evolve during the lifetime of a wireless LAN deployment, it is also necessary to provide a means of smoothly upgrading this feature set for the installed base of products, with minimal disruption to network operations.

Cisco’s unified wireless LAN feature set offers the features required for most enterprise deployments. Some deployments may not yet require these advanced capabilities. To address these evolving requirements, customers can select lightweight access points, or they can upgrade autonomous access points in the field to lightweight operation. With Cisco, customers can choose the feature set that is right for them, at the time that it is right for them. Table 1 provides a summary of the operational capabilities of various Cisco Aironet access points.

Table1. Operational Capabilities of Cisco Aironet Access Points

Operational Capabilities of Cisco Aironet Access Points

Addressing Capacity Requirements

In just a few years, WLANs have evolved from proprietary systems with sub-Mbps capabilities to standardized offerings operating at data rates as high as 600 Mbps for dual-band 802.11n access points. These high data rates are available by taking advantage of the emerging 802.11n draft 2.0 standard with radios operating in both the 2.4 GHz band and the 5 GHz band. 802.11n draft 2.0 offers backward compatibility with 802.11a/b/g devices. Both 802.11b/g and 802.11n draft 2.0 are limited to three no overlapping channels when deployed in the 2.4 GHz band. 802.11a and 802.11n draft 2.0 support as many as 23 channels in the 5 GHz band (depending upon local regulations). To provide both backward compatibility and high capacity, WLAN client vendors are migrating to 802.11n-capable client devices, although many devices will continue to support the 802.11a/b/g standards and the 802.11n support complete backwards compatibility to ensure investment protection.

Deploying an infrastructure that takes full advantage of next generation wireless with 802.11n makes sense if capacity or reliability is currently an issue or is expected to become an issue during the useful life of the infrastructure devices. Given the rapid expansion of wireless-enabled devices, increasing capacity requirements are likely to apply to most WLAN installations. For this majority of applications, access points that support the emerging 802.11n draft 2.0 standard represents a better long-term value, particularly given the low price premium relative to performance. For the few applications that are not expected to present capacity issues in the near term, customers can choose existing 802.11a/g dual-radio access points. Table 2 summarizes which Cisco access points support 802.11a, 802.11b, 802.11g, and the new 802.11n draft 2.0 standard.

Table2. Cisco Aironet Access Point Support for 802.11a/b/g and 802.11n draft 2.0

Cisco Aironet Access Point Support for 802 11abg and 802 11n draft 2 0-2

With a hardware upgrade module, Cisco Aironet 1200 Series Access Points may be field-upgraded to support 802.11a.

Award-Winning Security

The Cisco Aironet Series access points supports 802.11i, Wi-Fi Protected Access (WPA), WPA2, and numerous Extensible Authentication Protocol (EAP) types. WPA and WPA2 are the Wi-Fi Alliance certifications for interoperable, standards-based WLAN security. These certifications support IEEE 802.1X for user-based authentication, Temporal Key Integrity Protocol (TKIP) for WPA encryption, and Advanced Encryption Standard (AES) for WPA2 encryption. These certifications help to ensure interoperability between Wi-Fi-certified WLAN devices from different manufacturers.

Cisco Aironet Series Access Points operating with LWAPP support Cisco Unified Intrusion Detection System/Intrusion Prevention System (IDS/IPS), a software feature that is part of the Cisco Self-Defending Network and is the industry’s first integrated wired and wireless security solution. Cisco Unified IDS/IPS (Figure 1) takes a comprehensive approach to security—at the wireless edge, wired edge, WAN edge, and through the data center. When an associated client sends malicious traffic through the Cisco Unified Wireless Network, a Cisco wired IDS device detects the attack and sends shun requests to Cisco wireless LAN controllers, which will then disassociate the client device.

Figure1. Cisco Unified IDS/IPS Detects Malicious Attacks Allowing the WLAN Controller to Disassociate the Offending Client Device

Cisco Unified IDS

Autonomous or unified Cisco Aironet Series access points support management frame protection for the authentication of 802.11 management frames by the wireless network infrastructure. This allows the network to detect spoofed frames from access points or malicious users impersonating infrastructure access points. If an access point detects a malicious attack, an incident will be generated by the access point and reports will be gathered on the Cisco wireless LAN controller, Cisco WCS, or CiscoWorks WLSE.

Management and Deployment Flexibility

The Cisco Aironet Series access points are key elements of the Cisco Unified Wireless Network, a comprehensive solution that delivers an integrated, end-to-end wired and wireless network. Using the radio and network management features of the Cisco Unified Wireless Network for simplified deployment, the access points extend the security, scalability, reliability, ease of deployment, and manageability available in wired networks to the wireless LAN. In addition to management flexibility the Cisco Aironet Series offers investment protection deployment flexibility with Hybrid REAP and Link Role Flexibility.

Hybrid REAP

Hybrid Remote Edge Access Point (Figure 2) functionality is supported on the Cisco Aironet 1240AG and 1130AG Series Access Points. It allows users to deploy access points in remote offices, and choose whether they would like to have traffic bridged locally, or tunneled over the WAN over LWAPP on a per SSID basis. If users choose to bridge traffic locally, then it is bridged onto separate VLANs that directly correlate to an SSID (i.e. there is a 1:1 mapping of SSIDs to VLANs when traffic is bridged locally).

Figure2. Remote Edge Access Point (REAP) Capabilities Allow Users to Deploy Access Points in Remote Offices, and Choose Whether They Would Like to Have Traffic Bridged Locally, or Tunneled over the WAN over LWAPP on a Per-SSID Basis

Remote Edge Access Point (REAP) Capabilities

Users receive their IP address locally within the branch, but authenticate at a central site when using 802.1x, 802.11i, MAC authentication, web authentication, or NAC is in use. If any type of pre-shared key is used (i.e. WEP, WPA-PSK), then there is no need for central authentication.

After central authentication, the user traffic can still be bridged locally.

If a WAN link goes down, no new users using authentication can be added into the network, however users that have already authenticated remain connected. Users using pre-shared key remain connected and new pre-shared key users can still associate with the network since centralized authentication is not necessary. When the WAN link becomes active again, all users are disassociated and then authenticated to the network. This is used to ensure that the controller has accurate, up to date information about the users who are on the network.

Following are key elements of Hybrid REAP functionality:

Supported only on Cisco Aironet 1240AG and 1130AG Series Access Points.

8 advertised WLANs/SSIDs that terminate on a Controller or bridged locally.

Locally bridged WLAN/SSID can be mapped to a VLAN.

There is support for NAC/Web Auth/802.1x/802.11i on a per WLAN/SSID basis. These protocols are handled centrally, and subsequently the traffic can be bridged locally or continue to be tunneled back to the controller.

If an AP has never joined a Controller, it can be primed with an IP address, subnet mask, default gateway, and IP address of a Controller. After the AP has contacted the Controller the console is no longer available.

Cisco recommends that only two Hybrid REAPs be used in any one location over a WAN connection. This configuration is recommended because of the WAN bandwidth required.

Link Role Flexibility

The autonomous versions of the Cisco Aironet 1300 Series, 1240AG Series, 1230AG Series, and the 1200 Series offer link role flexibility, which provides both access point and bridge functions through configuration of each radio as an access point, repeater, root bridge, non-root bridge, or workgroup bridge. This configuration flexibility enables the access points to address a wide range of applications, including basic wireless LAN coverage, wireless LAN coverage with wireless backhaul, and more traditional bridging applications (Table 3).
