  • Details

    The Cisco® 5500 Series Wireless Controller, shown in Figure 1, is a highly scalable and flexible platform that enables systemwide services for mission-critical wireless networking in medium-sized to large enterprises and campus environments. Designed for 802.11ac and 802.11n performance and maximum scalability, the 5500 Series offers enhanced uptime with:

    ●   RF visibility and protection

    ●   The ability to simultaneously manage up to 500 access points

    ●   Superior performance for reliable streaming video and toll- quality voice

    ●   Sub-second stateful failover of all access points and clients from the primary to standby controller

    Figure 1.      Cisco 5500 Series Wireless LAN Controller



    Optimized for high-performance wireless networking, the Cisco 5500 Series Controller offers improved mobility and prepares the business for the next wave of mobile devices and applications. The 5500 Series supports a higher density of clients and delivers more efficient roaming, with at least nine times the throughput of existing 802.11a/g networks.

    The 5500 Series automates wireless configuration and management functions and allows network managers to have the visibility and control needed to cost-effectively manage, secure, and optimize the performance of their wireless networks. With integrated Cisco CleanAir®technology, the 5500 Series protects 802.11n performance by providing cross-network access to real-time and historic RF interference information for quick troubleshooting and resolution.

    The Cisco 5508 Wireless Controller supports Cisco Application Visibility and Control(AVC), the technology that includes the Network-Based Application Recognition 2 (NBAR-2) engine, Cisco’s deep packet inspection (DPI) capability. The NBAR-2 engine can classify applications, applies quality of service (QoS) setting to either drop or mark the traffic, and prioritizes business-critical applications in the network. Cisco AVC uses NetFlow Version 9 to export the flows to Cisco Prime Infrastructure or a third-party NetFlow Collector. The 5508 also supports Bonjour Services Directory to enable Bonjour Services to be advertised and utilized in a separate Layer 3 network. Wireless Policy engine is a wireless profiler and policy feature on the Cisco 5500 Series Wireless Controller that enables profiling of wireless devices and enforcement of policies such as VLAN assignment, QoS, ACL and time-of-day-based access.

    As a component of the Cisco Unified Wireless Network, this controller provides real-time communications between Cisco Aironet® access points, the Cisco Wireless Control System (WCS), and the Cisco Mobility Services Engine to deliver centralized security policies, wireless intrusion prevention system (IPS) capabilities, award-winning RF management, and QoS.

    Software Licensing Flexibility

    Base access point licensing offers flexibility to add up to 500 additional access points as business needs grow. The licensing structure supports a variety of business mobility needs as part of the basic feature set, including the Cisco OfficeExtend solution for secure, mobile teleworking and Cisco Enterprise Wireless Mesh, which allows access points to dynamically establish wireless connections in locations where it may be difficult or impossible to physically connect to the wired network.

    Table 1 lists the features of the Cisco 5500 Series Wireless LAN Controllers.

    The additive capacity licenses allow for the increase in access point capacity supported by the controller up to a maximum of 500 access points. As an example, if a controller was initially ordered with support for 250 access points, that capacity could be later increased to up to 500 access points by purchasing a 250-access-point additive capacity license (1x-LIC-CT5508-250A).

    A certificate with a PAK is required to add additional access point capacity on the Cisco 5500 Series Wireless Controller.

    The certificate may be expedited via email. If a paper certificate is required for customs, it should be ordered to ship via U.S. mail. Each additive capacity license and PAK must be registered prior to installation.

    Ordering and installing the Cisco 5500 Series Wireless Controller additive capacity licenses is a three-step process:

    1.     Select the correct SKU for email or paper delivery.

    2.     Register the PAK certificate (see Registering PAK Certificate).

    3.     Install the license on the Cisco 5500 Series Wireless Controller (see Installing License).

    Please review the Cisco Wireless LAN Controller Configuration Guide, Release 6.0 or later, for detailed ordering, registration, and installation information for the 5500 Series additive capacity licenses.

    Electronic delivery of the same PAKs is available by ordering the e-License SKUs as listed in Table 5. If a paper certificate is required, please use the SKUs listed in Table 6.

    PAK Certificate Registration

    Customers are required to register a PAK certificate for all upgrade licenses for the Cisco 5500 Series Wireless Controllers. Customer email address and host name are required to register the PAK certificate at:

    Installing License on Cisco WCS Server

    Follow these steps to install a license file. If you need additional help, contact Cisco Technical Assistance Center (TAC) at 800 553-2447 or

    1.     Install Cisco WCS software if not already completed.

    2.     Save the license file (.lic) to a temporary directory on your hard drive. (You will receive an email from Cisco with an attached license file)

    3.     Open a supported version of the Internet Explorer browser.

    4.     In the location or address field, enter the following URL, replacing IP address with the IP address or host name of the Cisco WCS server: https: // <IP address>.

    5.     Log in to the Cisco WCS server as system administrator. (Be aware that usernames and passwords are case-sensitive.)

    6.     From the Help menu, select Licensing.

    7.     On the Licensing page, from the Command menu, select Add License.

    8.     On the Add License page, click Browse to navigate to the location where you saved the .lic file.

    9.     Click Download. The Cisco WCS server imports the license.

    Table 7 shows the optional DTLS license for Cisco 5500 Series Wireless Controllers.

    Datagram Transport Layer Security (DTLS) is required for all OfficeExtend deployments to encrypt the Data Plane traffic. Customers planning to install this device physically in Russia must order the controller with DTLS disabled and then obtain a physical PAK in order to enable a DTLS license and should not download the license from Please consult your local government regulations to ensure that Data DTLS encryption is permitted.

    If a customer chooses SWC5500K9-60, SWC5500K9-70 or SWC5500K9-72, DTLS Data Encryption is enabled by default. When a customer orders the 5500 Series and chooses either SWC5500LPE-K9-70 or SWC5500LPE-K9-72 in the Optional Licenses tab, data DTLS Encryption is disabled.

    The DTLS Paper PAK license is designated for customers who purchase a controller with DTLS disabled due to import restrictions but get permission to add DTLS support after initial purchase. This optional DTLS license is required for Cisco OfficeExtend deployment.
