Converged Access – Configure SSID for CWA using ISE on 3850 Switches and 5760 Controller





    In the document Cisco TAC escalation engineer "Viten Patel" has explained "How to Configure SSID for Central Web Authentication (CWA) using ISE on Catalyst 3850 Switches and 5760 Wireless Controller".

    Unified Access CT5760 Wireless Controller

    The CT5760 Wireless LAN Controller (WLC) is the first Cisco IOS® software-based controller built with smart ASIC intended to be deployed as a centralized controller in the next generation unified wireless architecture. CT5760 controllers are specifically designed to function like the older unified model central wireless controllers. They also support the newer Mobility functionality with Next Generation Wireless Controllers 3850 switches in the wireless architecture.

    CT5760 controllers are deployed behind a core switch/router. The core switch/router is the only gateway into the network for the controller. The uplink ports connected to the core switch are configured as EtherChannel trunk to ensure port redundancy.

    This new controller is an extensible and high performance wireless controller, which can scale up to 1000 access points (AP) and 12,000 clients. The controller has eight 6-10 Gbps data ports.

    As a component of the Cisco Unified Wireless Network, the 5760 series works in conjunction with Cisco Aironet Access Points, the Cisco Prime Infrastructure, and the Cisco Mobility Services Engine to support business-critical wireless data, voice, and video applications.

    Unified Access Catalyst 3850 Switches

    The Unified Access Catalyst 3850 switch is a flexible ASIC-based hardware that can support multiple protocols and has many advantages over the current hardware platform. The Catalyst

    3850 switch has an integrated hardware-based wireless support with Control and Provisioning of Wireless Access Points (CAPWAP) and fragmentation. It also has 40 GB of uplink bandwidth when all ports function at line rate.

    The Catalyst 3850 switch provides an open service platform. It has a 4-core CPU to leverage the operating system (OS) and to host various services. The Catalyst 3850 hardware is the next- generation switching hardware.

    The UA Catalyst 3850 switch has unified wired and wireless architecture. The wireless operating system is Cisco IOS® software-based. UA Catalyst 3850 switch provides uniform wired and wireless policies. It can house 50 access points (802.11n) and support 2000 clients per stack.

    Hello Vinay,

    A great resourse libary - hence my 5 star rating.


    I can see that this was posted over 1 year ago so I still hope that you catch this message.

    I am new to converged access but i am currently desinging a new network solution which will not have any Cisco ISE or dedicated WLC. All WLC functions will be hosted of 3850 swtiches.


    My query is for corp and guest user (SSID) authentication. As we are not using a dedicated Cisco ISE for this single site branch deployment, the client is looking to provide a 3rd pary radius server and i think i can use the configuration guidance for ISE...since this looks to be the right template for radius?

    Many thanks in advance

    Best wishes
