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

● Limited lifetime warranty

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.
