Site Requirements, For Infrastructure Devices

Chapter 2 Preparing for Installation

Site Requirements

•If your wireless network uses PEAP authentication with a One-Time Password (OTP) user database:

–SofToken version 1.3, 2.0, or later from Secure Computing; SecurID version 2.5 from RSA; or hardware token from OTP vendors

–Your software token PIN or hardware token password

•If your wireless network uses EAP-SIM authentication:

–PCSC-compliant smartcard reader installed in your computer’s Type II or Type III PC card slot

–Gemplus SIM+ smartcard inserted in the reader

–The SIM card’s PIN

Note The EAP-SIM supplicant included in the Install Wizard file supports only Gemplus SIM+ cards; however, an updated supplicant is available that supports standard GSM-SIM cards as well as more recent versions of the EAP-SIM protocol. The new supplicant is available for download from Cisco.com at the following URL: http://www.cisco.com/cgi-bin/tablebuild.pl/access-registrar-encrypted

•The following information from your system administrator:

–The logical name for your workstation (also referred to as client name)

–The protocols necessary to bind to the client adapter

–The case-sensitive service set identifier (SSID) for your RF network

–If your network setup does not include a DHCP server, the IP address, subnet mask, and default gateway address of your computer

–The wired equivalent privacy (WEP) keys of the access points with which your client adapter will communicate, if your wireless network uses static WEP for security

–The username and password for your network account

–Protected access credentials (PAC) file if your wireless network uses EAP-FAST authentication with manual PAC provisioning

Site Requirements

This section discusses the site requirements for both infrastructure and client devices.

For Infrastructure Devices

Because of differences in component configuration, placement, and physical environment, every network application is a unique installation. Therefore, before you install any wireless infrastructure devices (such as access points, bridges, and base stations, which connect your client adapters to a wired LAN), a site survey must be performed to determine the optimum placement of these devices to maximize range, coverage, and network performance. Appendix F, which is provided for people who are responsible for conducting a site survey, explains how ACU’s site survey tool can be used to determine the best placement for infrastructure devices within a wireless network.

Note Infrastructure devices are installed and initially configured prior to client devices.

Cisco Systems has long been a prominent player in the realm of networking and communications technology. Among its comprehensive product lineup, the Cisco 350 and 340 series of switches stand out as reliable solutions for businesses looking to enhance their network performance.

The Cisco 350 series, often referred to for its accessibility and performance, is designed for small to medium-sized enterprises. It offers a versatile set of features that cater to various networking needs. Key characteristics include a range of models supporting 10/100/1000 Mbps Ethernet ports, which allow for high-speed connectivity. The series also supports PoE (Power over Ethernet) capabilities, enabling devices such as IP phones and wireless access points to receive power directly through the network connection. This not only simplifies deployment but also minimizes the need for additional power supplies.

Cisco's Intelligent Prosumer Networking features are incorporated into the 350 series, enabling enhanced security and management capabilities. The switches provide Layer 2 and Layer 3 functionality for routing and switching, allowing users to segment their networks efficiently and reduce broadcast traffic. Additionally, Quality of Service (QoS) features prioritize critical applications, ensuring a smooth user experience without interruptions.

On the other side, the Cisco 340 series builds on similar performance foundations but targets environments requiring even more robust capabilities. It includes advanced features such as StackWise technology, which provides scalability and redundancy. This allows multiple switches to operate as a single unit, improving network resilience and simplifying management.

Both the 350 and 340 series incorporate Cisco's Smart Group technology, facilitating streamlined configuration and easier monitoring of network performance. Furthermore, with Cisco DNA (Digital Network Architecture) capabilities, these switches can support automation and insights through analytics, enabling IT teams to respond rapidly to network demands.

In terms of security, both series are equipped with advanced features that prevent unauthorized access and support secure management protocols. They include features like Access Control Lists (ACLs) and storm control, further protecting network integrity.

Overall, whether you opt for the Cisco 350 or 340 series, you will benefit from a robust set of features designed for modern networking challenges, along with the innovation and reliability that Cisco Systems is known for. These switches provide scalable, efficient, and secure solutions to support business growth and operational efficiency.
