Cisco Systems SRW224G4 User's Manual

Secure, reliable, intelligent,

SNMP managed switching for growing businesses

The Linksys WebView Managed switch allows you to expand your network securely.

Configuration of the switch is secured using SSL for Web access and SSH for Telnet access. User control is secured using 802.1x security using a RADIUS authentication mechanism and can also be controlled using MAC filtering.

Extensive Quality of Service (QoS) features make the solution ideal for real-time applications like Voice and Video. The 4 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), Layer 3 priority (TOS or DSCP), or IPv6 Traffic Class. Intelligent Broadcast, Multicast, and Unknown Unicast storm control minimizes and contains the effect 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 setup. Spanning

Tree, Rapid Spanning Tree, and Multiple Spanning Tree allow you to build a mesh of switches increasing the availability of the system. This also provides a level of reliability in that the system continues to operate even if one of the links breaks.

The rich management functionality of the WebView switches includes SNMP, RMON, Telnet, and HTTP Management options, allowing you to flexibly integrate and manage these devices in your network.
