Cisco SRW208G 8-Port 10/100 Ethernet Switch: WebView/Expansion Slots

Secure, Reliable, Intelligent Switching for Small Businesses

Highlights
• Connects up to eight network devices - PCs, printers, and servers - to share and transfer files and videos across your network
• Strong security protects network traffic to keep unauthorized users off the network
• Intelligent QoS helps ensure a consistent network experience and supports networked applications including voice, video, and data storage
• Simplified, web-based management for easy installation and configuration
• Compact size provides multiple placement options for areas with limited space

Growing businesses require cost-effective networking solutions that can scale with ever-changing business needs. The Cisco® SRW208G 8-Port 10/100 Ethernet Switch brings a new level of intelligence and security to the network infrastructure. Its intelligence and small size make it ideal for a conference room or training room where security and uptime are important. It offers a port for connecting a Gigabit copper or optical interface to the core network.
Network security is a top priority in any business. Most business data networks, large and small, are unsecured. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW208G is able to secure the network through 802.1X port authentication and MAC-based filtering. The 802.1X standard requires clients to authenticate themselves before the port will pass data for them.
Businesses are recognizing the benefits of 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 quality of service (QoS) and traffic management features in the Cisco SRW208G, voice data can be prioritized, helping ensure clear and reliable voice communications.
Enabling the advanced features of the Cisco SRW208G further secures the integrity of your network. The WebView interface provides an intuitive, highly secure management interface, enabling you to better utilize the comprehensive feature set of the switch, for a better-optimized, more secure network.
