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.

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

Dual images for resilient firmware upgrades

Up to 12.8-Gbps nonblocking, store-and-forward switching capacity

Simplified quality of service (QoS) management using 802.1p, Differentiated Services (DiffServ), or type of

service (ToS) traffic prioritization specifications

Fully resilient stacking provides optimized growth with simplified management

ACLs for granular security and QoS implementation

Can be configured and monitored from a standard web browser

Secure remote management of the switch via Secure Shell (SSH) and Secure Sockets Layer (SSL)

encryption

802.1Q-based VLANs enable segmentation of networks for improved performance and security

Private VLAN Edge (PVE) for simplified network isolation of guest connections or autonomous networks

Automatic configuration of VLANs across multiple switches through Generic VLAN Registration Protocol

(GVRP) and Generic Attribute Registration Protocol (GARP)

User/network port-level security via 802.1X authentication and MAC-based filtering

Increased bandwidth and added link redundancy with link aggregation

Enhanced rate-limiting capabilities, including back pressure, multicast, and broadcast flood control

Port mirroring for noninvasive monitoring of switch traffic

Mini jumbo frame support (1600 bytes)

Simple Network Management Protocol (SNMP) v1, v2c, v3 and Remote Monitoring (RMON) support

Fully rack-mountable using the included rack-mounting hardware

Simple, one-step automated installation and initial configuration
