Introduction

This document introduces the maintenance release 3.2.2 Web GUI functionality for the Cisco Converged Access CT5760 and Cat3850 products. This guide is designed to help you access, configure, and monitor both products using the Web GUI interface.

CT5760 Controller

CT5760 is an innovative UADP ASIC based wireless controller deployed as a centralized controller in the next generation unified wireless architecture. CT5760 controllers are specifically designed to function as the Unified model central wireless controllers. They also support the newer Mobility functionality with Converged Access 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 performing wireless controller, which can scale up to 1000 access points and 12000 clients. The controller has 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.

Catalyst 3850 Switches

Unified Access Catalyst 3850 switches are innovative UADP ASIC hardware that can support multiple protocols and has many advantages over the current hardware platform. CAT3850 switch has an integrated hardware based wireless support with CAPWAP and fragmentation. The CAT3850 switch has 40gig of uplink bandwidth with all port functioning at line rate.

The CAT3850 switches provide Open Service platform. It is a 4 core CPU to leverage the OS and to host various services. The CAT3850 hardware is the Next-Gen switching hardware.

UA CAT3850 switches have unified wired and wireless architecture. The wireless operating system is IOS based. UA CAT3850 switches provide uniform wired and wireless policies. The CAT3850 switch can manage 50 access points (802.11n) and support 2000 clients per stack.

Getting Started

Before you get started with enabling the WEB GUI on the Cat3850/CT5760, make sure you have the following:

1. CLI access to the box. Console Access information is shown in the CLI/Console Access section.

2. Have one of the Supported Browser Version as listed in the section.

3. Go through the release notes for Release 3.2.2 located at:

http://www.cisco.com/en/US/docs/switches/lan/catalyst3850/software/release/3.2_0_se/release_notes/OL28114.html#wp223882

4. Have access information such as Username/Password and networking access information.

Supported Browser Version

The following is a list of supported browser versions:

  • Chrome – Ver. 26.x
  • Mozilla – Ver. 20.x
  • IE – Ver. 8.x, 9.x and 10.x

CLI/Console Access

Before you configure the switch or controller for basic operations, you must connect it to a PC that uses a VT-100 terminal emulator (such as, HyperTerminal, ProComm, or Putty).

The controller has both EIA/TIA-232 asynchronous (RJ-45) and USB 5-pin mini Type B, 2.0 compliant serial console ports. The default parameters for the console ports are 9600 baud, 8 data bits, 1 stop bit, and no parity. The console ports do not support hardware flow control. Choose the serial baud rate of 9600; if you have issues, try a baud rate of 115200. The figure below shows an example of a Mac Secure CRT; use similar configuration for PC/Windows Putty, and so on.
