Chapter 1 Overview

VLAN Support

Avoiding and managing network congestion

Prioritizing service to different kinds of network traffic

Shaping network traffic

Setting traffic priorities across the network

Limitations and Restrictions

The QoS implementation on the bridge has the following limitations and restrictions:

Provides only prioritized QoS for downlink traffic on IEEE 802.11 links and does not support a general purpose QoS signalling protocol, uniform admission control, guaranteed bandwidth, and other features that are generally associated with parametized QoS.

Supports rudimentary admission control mechanisms for Spectralink and Symbol VoIP phones.

Does not provide a method for prioritizing uplink traffic on IEEE 802.11 links.

Does not offer 802.1X authentication for Symbol VoIP phones because those phones do not support an 802.1X type such as LEAP or EAP-TLS.

The DTIM beacon period must be small to support jitter-sensitive streaming multicast audio and video applications.

Supports IEEE 802.11e EDCF-like channel access prioritization but does not support IEEE 802.11e QoS frame formats.

VLAN Support

Version 12.01T supports VLAN technology by mapping SSIDs to VLANs. With the multiple-SSID capability, the bridge can support up to 16 VLAN subnets.

What is a VLAN?

A switched network can be logically segmented into virtual local-area networks (VLANs), on a physical or geographical basis, or by functions, project teams, or applications. For example, all workstations and servers used by a particular workgroup team can be connected to the same VLAN regardless of their physical connections to the network or the fact that they might be intermingled with devices for other teams. Reconfiguration of VLANs can be done through software rather than physically unplugging and moving devices or wires.

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.
