What you should pay attention to cisco aironet access point while purchasing

  1. 1. What You Should Pay Attention to Cisco Aironet Access Point While Purchasing?General Information of Cisco Aironet Access PointAs WLAN deployments expand, security, scalability, reliability, ease of deployment,and management become increasingly important. Cisco provides a comprehensiveline of access points that deliver enterprise-class features for business-ready wirelessLANs.Executive SummaryAccess points are critical elements of the CiscoUnified Wireless Network. Ciscosingle- and dual band access points are designed for offices and similar environments,challenging RF environments, and the outdoors. The devices are available in twoversions: unified or autonomous. Unified access points operate with the LightweightAccess Point Protocol (LWAPP) and work in conjunction with Cisco wireless LANcontrollers and the Wireless Control System (WCS).Autonomous access points are based on Cisco IOSSoftware and may optionallyoperate with the CiscoWorks Wireless LAN Solution Engine (WLSE). Autonomousaccess points, along with the WLSE, deliver a core set of features and may befield-upgraded to take advantage of the full benefits of the Cisco Unified WirelessNetwork as requirements evolve.To make the best choices for their particular applications, customers need tounderstand the features and benefits of the different Cisco Aironetaccess points. Thissolution overview details the capabilities of each of the devices in the Cisco AironetFamily of wireless access points.Management ParadigmAs wireless LANs become increasingly mission-critical and evolve in terms of scale
  2. 2. and capabilities, the way the wireless deployment is managed must evolve as well.Because each customer and each deployment is unique, Cisco provides differingfeature sets and differing paradigms to address these customer-specificrequirements.Cisco provides a core feature set that includes autonomous access points and theCiscoWorks WLSE management appliance. The core feature set provides a base set ofcapabilities that are required for enterprise deployments. Core features includesecure 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-partyapplications and products. Most Cisco access points are available in versionsdesigned for autonomous operation. These devices may be upgraded in the field tolightweight mode, thereby providing customers with a smooth path from core tounified features.The Cisco unified feature set is delivered by lightweight access points, wireless LANcontrollers, and the Wireless Control System (WCS) management solution. Theunified feature set represents the most comprehensive set of capabilities in theindustry, including guest access, wireless intrusion detection and intrusionprevention, scalable Layer 3 mobility, and location services. Most Cisco Aironetaccess points are available in versions designed for lightweight operation.Deployment EnvironmentsWireless LANs are becoming commonplace in numerous environments, includingoffices, schools, factories, warehouses, and even the outdoors. At the same time, thewireless industry is evolving from lower-capacity, single-band devices tohigh-capacity, dual-band solutions. The Cisco AironetFamily of access points meets these various application requirements by providing:Single- and dual-band access pointsDevices designed for indoor and outdoor deploymentsA consistent hardware feature set and predictable RF performance for deploymentacross the enterpriseAs WLAN deployment expands into more applications and installation scenarios, adiverse line of access points is required to meet the associated capacity, coverage,and environmental requirements. The Cisco product line includes access pointsdesigned for offices and similar facilities, such as hospitals and retail environments,challenging RF environments like factories and warehouses, and the outdoors. Thesedevices can be installed on desktops, on walls, on ceilings, above ceilings, and on topof poles.While application requirements may vary, Cisco understands that all enterprisecustomers require uncompromised network security, scalable manageability, and anevolving set of networkservices. That’s why all Cisco Aironet access points support
  3. 3. the Cisco Unified Wireless Network, a framework for wired and wireless integrationthat delivers the security, manageability, and services that enterprises have come toexpect from Cisco on both wired and wireless networks.SolutionAddressing Feature RequirementsAs wireless LAN usage has evolved from basic transport for largely transactionalapplications, so have the feature expectations of wireless LAN users andadministrators. This change has come about on a segment-by-segment,customer-by-customer basis. It is critical for Cisco to provide differing feature sets tobest fit differing customer requirements. Given that customer requirements canevolve during the lifetime of a wireless LAN deployment, it is also necessary toprovide a means of smoothly upgrading this feature set for the installed base ofproducts, with minimal disruption to network operations.Cisco’s unified wireless LAN feature set offers the features required for mostenterprise deployments. Some deployments may not yet require these advancedcapabilities. To address these evolving requirements, customers can selectlightweight access points, or they can upgrade autonomous access points in the fieldto lightweight operation. With Cisco, customers can choose the feature set that isright for them, at the time that it is right for them. Table 1 provides a summary of theoperational capabilities of various Cisco Aironet access points.Table1.Operational Capabilities of Cisco Aironet Access PointsAddressing Capacity RequirementsIn just a few years, WLANs have evolved from proprietary systems with sub-Mbpscapabilities to standardized offerings operating at data rates as high as 600 Mbps fordual-band 802.11n access points. These high data rates are available by takingadvantage of the emerging 802.11n draft 2.0standard with radios operating in boththe 2.4 GHz band and the 5 GHz band. 802.11n draft 2.0 offers backwardcompatibility with 802.11a/b/g devices. Both 802.11b/g and 802.11n draft 2.0 arelimited 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
  4. 4. 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 the802.11n support complete backwards compatibility to ensure investment protection.Deploying an infrastructure that takes full advantage of next generation wireless with802.11n makes sense if capacity or reliability is currently an issue or is expected tobecome an issue during the useful life of the infrastructure devices. Given the rapidexpansion of wireless-enabled devices, increasing capacity requirements are likely toapply to most WLAN installations. For this majority of applications, access points thatsupport 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 fewapplications that are not expected to present capacity issues in the near term,customers can choose existing 802.11a/g dual-radio access points. Table 2summarizes which Cisco access pointssupport 802.11a, 802.11b, 802.11g, and thenew 802.11n draft 2.0 standard.Table2. Cisco Aironet Access Point Support for 802.11a/b/g and 802.11n draft 2.0With a hardware upgrade module, Cisco Aironet 1200 Series Access Points may befield-upgradedto support 802.11a.Award-Winning SecurityThe Cisco Aironet Series access points supports 802.11i, Wi-Fi Protected Access(WPA), WPA2, and numerous Extensible Authentication Protocol (EAP) types. WPAand WPA2 are the Wi-Fi Alliance certifications for interoperable, standards-basedWLAN security. These certifications support IEEE 802.1X for user-basedauthentication, Temporal Key Integrity Protocol (TKIP) for WPA encryption, andAdvanced Encryption Standard (AES) for WPA2 encryption. These certifications helpto ensure interoperability between Wi-Fi-certified WLAN devices fromdifferentmanufacturers.Cisco Aironet Series Access Points operating with LWAPP support Cisco UnifiedIntrusion Detection System/Intrusion Prevention System (IDS/IPS), a software featurethat is part of the Cisco Self-Defending Network and is the industry’s first integratedwired and wireless security solution. Cisco Unified IDS/IPS (Figure 1) takes acomprehensive approach to security—at the wireless edge, wired edge, WAN edge,
  5. 5. and through the data center. When an associated client sends malicious trafficthrough the Cisco Unified Wireless Network, a Cisco wired IDS device detects theattack and sends shun requests to Cisco wireless LAN controllers, which will thendisassociate the client device.Figure1.Cisco Unified IDS/IPS Detects Malicious Attacks Allowing the WLANController to Disassociate the Offending Client DeviceAutonomous or unified Cisco Aironet Series access points support managementframe protection for the authentication of 802.11 management frames by thewireless network infrastructure. This allows the network to detect spoofed framesfrom access points or malicious users impersonating infrastructure access points. Ifan access point detects a malicious attack, an incident will be generated by theaccess point and reports will be gathered on the Cisco wireless LAN controller, CiscoWCS, or CiscoWorks WLSE.Management and Deployment FlexibilityThe Cisco Aironet Series access points are key elements of the Cisco Unified WirelessNetwork, a comprehensive solution that delivers an integrated, end-to-end wiredand wireless network. Using the radio and network management features of theCisco Unified Wireless Network for simplified deployment, the access points extendthe security, scalability, reliability, ease of deployment, and manageability available inwired networks to the wireless LAN. In addition to management flexibility the CiscoAironet Series offers investment protection deployment flexibility with Hybrid REAPand Link Role Flexibility.Hybrid REAPHybrid Remote Edge Access Point (Figure 2) functionality is supported on the CiscoAironet 1240AG and 1130AG Series Access Points. It allows users to deploy accesspoints in remote offices, and choose whether they would like to have traffic bridged
  6. 6. locally, or tunneled over the WAN over LWAPP on a per SSID basis. If users choose tobridge traffic locally, then it is bridged onto separate VLANs that directly correlate toan 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 DeployAccess Points in Remote Offices, and Choose Whether They Would Like to HaveTraffic Bridged Locally, or Tunneled over the WAN over LWAPP on a Per-SSID BasisUsers receive their IP address locally within the branch, but authenticate at a centralsite when using 802.1x, 802.11i, MAC authentication, web authentication, or NAC isin use. If any type of pre-shared key is used (i.e. WEP, WPA-PSK), then there is noneed 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 thenetwork, however users that have already authenticated remain connected. Usersusing pre-shared key remain connected and new pre-shared key users can stillassociate with the network since centralized authentication is not necessary. Whenthe WAN link becomes active again, all users are disassociated and thenauthenticated to the network. This is used to ensure that thecontroller 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,
  7. 7. 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 FlexibilityThe autonomous versions of the Cisco Aironet 1300 Series, 1240AG Series, 1230AGSeries, and the 1200 Series offer link role flexibility, which provides both access pointand bridge functions through configuration of each radio as an access point, repeater,root bridge, non-root bridge, orworkgroup bridge. This configuration flexibilityenables the access points to address a wide range of applications, including basicwireless LAN coverage, wireless LAN coverage with wireless backhaul, and moretraditional bridging applications (Table 3).Table3. Wireless LAN Link Role Flexibility Applications for Dual-Band Access PointsNote: Only one 802.11g radio and one 802.11a radio are supported.Office Access PointsCisco Aironet 1130AG Series IEEE 802.11a/b/g Access PointPackages high-capacity, high-security, and enterprise-class features to deliverwireless LAN access for a low total cost of ownership.
