Introduction

Thank you for choosing the Linksys 24/48-Port 10/100

+4-Port Gigabit Smart Switch with Resilient Clustering Technology and PoE.

These switches allow you to expand your network securely. User control is secured using 802.1x security using a RADIUS authentication mechanism and can also be controlled using MAC filtering.

For Wireless or VoIP deployments, the SLM224G4PS and SLM248G4PS Switches support the IEEE802.3af standard for Power over Ethernet (PoE), allowing you to attach PoE- enabled devices to your network. These devices need no additional power cables or nearby power outlets, resulting in simpler and less expensive installation. PoE support also allows devices like cameras and Wireless Access Points to be positioned in optimal locations, such as in ceilings and walls—even outdoors.

Extensive QoS features makes the solution ideal for real- time applications like Voice and Video. The four priority queues together with the Weighted Round Robin and Strict Priority scheduling techniques facilitate efficient co-existence of real-time traffic with data traffic allowing them each to meet their QoS needs. Individual users or applications can be prioritized above others using various Class of Service options—by port, Layer 2 priority (802.1p), and Layer 3 priority (TOS or DSCP). Intelligent Broadcast and Multicast storm control minimize and contain the effects of these types of traffic on regular traffic. IGMP Snooping limits bandwidth-intensive video traffic to only the requestors without flooding to all users. Incoming traffic can be policed and outgoing traffic can be shaped allowing you to control network access and traffic flow.

There are features that allow you to expand and grow your network of switches. Link aggregation allows multiple high-bandwidth trunks between switches to be set up. This also provides a level of reliability in that the system continues to operate if one of the links breaks. Spanning Tree (STP) and Fast Link allow you to build a mesh of switches increasing the availibility of the system.

The rich management functionality of the Smart Switches with Resilient Clustering Technology includes SNMP, RMON, Telnet, and HTTP Management options, allowing you to flexibly integrate and manage these devices in your network.

NOTE: Throughout this User Guide, the term reset refers to cycling the power to the Switch; that is, powering the Switch off, then on again.
