Linksys SRW208L User Manual

Secure, reliable, intelligent, managed
switching for your growing business

Growing businesses require cost effective, networking solutions that can scale with
ever changing business needs. The Linksys SRW208L Switch with WebView brings
a whole new level of intelligence and security to the network infrastructure. The
combination of its intelligence and small size make it ideal for a conference room or
training room where security and uptime are important. It offers a miniGBIC port and a
100 Mbps intermediate reach optical interface for connection to a core switch.

Network security is a top priority in any size business. Most business data networks, large
and small, are unsecured. Unauthorized access to the network and mission critical data
is a constant concern. The SRW208L is able to secure the network through 802.1X port
authentication and MAC-based filtering. 802.1X requires clients to authenticate themselves
before the port will pass data.

Businesses are recognizing the benefits of doing Voice over IP (VoIP) and are quickly
migrating their voice services to IP based platforms, requiring their local area networks to
support both voice and data applications. In unmanaged IP networks, bursty data sessions
can disrupt voice packet delivery, causing poor voice quality. With the enhanced QoS and
traffic management features in the SRW208L, voice data can be prioritized, ensuring clear and
reliable voice communications.

SRW208L

Enabling the SRW208L advanced features further secures the integrity of your network. The
WebView interface provides an intuitive, secure management interface enabling you to better
utilize the comprehensive feature-set of the switch, resulting in a better optimized, more secure
network.
