SRW2048

Secure, reliable, intelligent, high density

managed switching for your network core

Optimized to be your

network core with

very high perfor-

mance and density

Intelligent traffic man-

agement with Rate

Limiting, Policing, Shap-

ing, and Storm control

Secure management

via SSH/SSL and secure

user control via 802.1x

& MAC filtering

IGMP snooping, L2/L3

COS, queuing & sched-

uling makes solution

ideal for Voice/Video

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 QoS features makes the solution ideal for real-time applications like Voice and Video. The 4 pri-

ority 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 contain the effect of these types of traffic on

regular traffic. IGMP Snooping limits bandwidth-intensive video traffic to only the requestors without flood-

ing to all users. Incoming traffic can be policed and outgoing traffic can be shaped allowing you to con-

trol network access and traffic flow.

There are features that allow you to expand and grow your network of switches. Link aggregation allow

multiple high-bandwidth trunks between switches to be setup. This also provides a level of reliability in that

the system continues to operate if one of the links break. Spanning Tree(STP), Fast Spanning Tree, and Mul-

tiple Spanning Tree allow you to build a mesh of switches increasing the availibility of the system.

The rich management functionality of the WebView switches includes SNMP, RMON, Telnet, and HTTP Man-

agement options, allowing you to flexibly integrate and manage these devices in your network.
