Help your business achieve its fullest potential by putting a strong internal network in place. Formerly a part of the Linksys Business Series, the Cisco SRW2016 16-port Gigabit Switch is the heart of a digital environment. The switch supports gigabit networking, offering you exemplary performance over 16 separate connections. Because security is a priority, the SRW2016 sends no information to an attached device without authentication, and allows access levels to be customized in multiple ways.
The SRW2016 prioritizes dataflow with a variety of traffic-shaping mechanisms. This helps ensure high performance and clarity for heavy-traffic communications like video teleconferencing. The switch's robust management functions are easy to access using a variety of clients, and its internal monitoring software keeps tabs on your network's every operation.
Additional features of the Cisco SRW2016 16-port Gigabit Switch include:
- Non-blocking switching capacity of up to 32 Gbps
- Up to 256 active port- and 802.1Q-based VLANs (4096 range)
- Two shared miniGBIC ports for future-proofed network expansion
- 16 autosensing 10/100/1000 full duplex, auto MDI/MDI-X ports
- WebView remote monitoring and configuration via web browser
Growing businesses require cost-effective networking solutions that can scale to meet ever-changing business needs. The Cisco® SRW2016 16-Port Gigabit Switch (Figure 1) brings Gigabit speeds to your users and servers, while adding a new level of intelligence and security to the network infrastructure. The sixteen 10/100/1000 Mbps ports enable you to take advantage of the Gigabit Ethernet interfaces shipping in the current generation of servers, workstations, and storage devices, in addition to supporting your existing 10/100 Mbps clients. The optional Gigabit optical interfaces allow you to expand the network as your business grows.
Network security is a top priority in any size business. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW2016 is able to secure the network through 802.1x port authentication. 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 QoS and traffic management features in the Cisco SRW2016, voice data can be prioritized, helping ensure clear and reliable voice communications.
Enabling the advanced features of the Cisco SRW2016 further secures the integrity of your network. The WebView interface provides an intuitive, secure management interface, helping you better utilize the comprehensive feature set of the switch, for a better-optimized, more secure network.
