Management Options, Roaming Client Devices

Chapter 1 Overview

Management Options

–The client generates a double encrypted session key and sends it to the access point along with the chosen cipher specification.

–The access point authenticates the client based on a user ID and password when the user manager feature is enabled.

–If authentication is successful, all management traffic between the client and access point is encrypted using the session key.

Management Options

You can use the bridge management system through the following interfaces:

•A web-browser interface

•A command-line interface (CLI)

•Simple Network Management Protocol (SNMP)

The bridge’s management system pages are organized the same way for the web- browser interface and the CLI. The examples in this manual are all taken from the web-browser interface. Chapter 2, “Using the Management Interfaces” provides a detailed description of each management option.

Roaming Client Devices

If you have more than one bridge or access point in your wireless LAN, wireless client devices can roam seamlessly from one bridge or access point to another. The roaming functionality is based on signal quality, not proximity. When a client’s signal quality drops, it roams to another bridge or access point.

Wireless LAN users are sometimes concerned when a client device stays associated to a distant bridge or access point instead of roaming to a closer bridge or access point. However, if a client’s signal to a distant bridge or access point remains strong, the client will not roam to a closer bridge or access point. If client devices checked constantly for closer bridges and access points, the extra radio traffic would slow throughput on the wireless LAN.

Quality of Service Support

The bridge now supports Cisco’s QoS, primarily in the area of wireless VoIP telephones from Spectralink and Symbol Technologies Corporation. The bridge also provides priority classification, prioritized queueing, and prioritized channel access for other downlink IEEE 802.11 traffic such as streaming audio or video traffic.

With this software release, the bridge does not include any QoS enhancements in Cisco IEEE 802.11 client software.

What is QoS?

QoS refers to the ability of a network to provide improved service to selected network traffic over various underlying technologies including Ethernet and wireless LANs. In particular, QoS features provide improved and more predictable network service by providing the following services:

•Improving loss characteristics

350 specifications

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.
