The Cisco SFE2010 48-Port 10/100 Ethernet Switch allows you to expand your network securely. Web-based configuration of the switch is secured using SSL. The Cisco SFE2010 is optimized for maximum system availability, with fully redundant stacking, redundant power options, and dual images for resilient firmware upgrades. The switch helps secure the network through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, access control lists (ACLs), denial-of-service (Dos) prevention, and MAC-based filtering. The enhanced quality of service (QoS) and traffic-management features help ensure clear and reliable voice and video communications.The Cisco SFE2010 provides resilient stacking for up to four units, or 192 ports. A stack of units is managed as a single switch with one web management interface. The SFE2010 switch can coexist in a stack with the Cisco SFE2000 and SFE2000P 24-Port 10/100 Ethernet Switches and the Cisco SFE2010P 48-Port 10/100 Ethernet Switch, for a maximum of 192 ports in a stack. The stacking capability includes master/backup unit behavior, ring and chain architecture, and hot insertion and removal of units. An intuitive, highly secure management interface provides access to the comprehensive feature set of the Cisco SFE2010, for a better-optimized, more secure network.
