Product Overview

The Cisco® SFE2000 24-Port 10/100 Ethernet Switch (Figure 1) is optimized to maximize system availability, with fully redundant stacking, redundant power options, and dual images for resilient firmware upgrades. The Cisco SFE2000 is able to 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 QoS and traffic management features help ensure clear and reliable voice and video communications.

The Cisco SFE2000 provides an intuitive, secure management interface, enabling you to better utilize the switch’s comprehensive feature set, resulting in a better-optimized, more secure network.
