Cisco SFE2000 24-Port 10/100 Ethernet Switch
Cisco Small Business Managed Switches
Secure, Flexible Switches for Small Business Network Foundations
Highlights
●Designed for small businesses that require speed, flexibility, and performance
●Resilient clustering provides the ability to manage several switches as a single switch to
support growing businesses
●QoS helps ensure a consistent network experience and supports networked applications
including voice, video, and data storage
●Strong security protects network traffic to keep unauthorized users off the network

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.
Features
●Twenty-four 10/100 Ethernet ports plus four 10/100/100 copper ports
●Two Small Form-Factor Pluggable (SFP) slots (shared with two copper ports) for fiber
Gigabit Ethernet expansion
