Get to Know the Sx250 Series Smart Switches

Introduction

The Cisco Sx250 Series Smart Switches are designed to be easy to configure, manage, and troubleshoot, allowing you to focus on your business priorities. These switches are equipped with a new generation of highly-integrated, cost-effective packet processors targeted for Carrier Ethernet and Small-Medium Enterprise (SME) applications with full wire-speed performance Fast Ethernet (FE) or Gigabit Ethernet (GE) ports, and GE Combo platforms.

The web-based utility allows you to deploy and manage your network efficiently. Setting up and troubleshooting can be done easily with easy-to-use tools such as Cisco Discovery Protocol (CDP), FindIT Network Management, and Cisco Smartports, which let your network automatically detect and configure all connected Cisco devices.

This article shows the features and functions of the Sx250 Smart Switches.
