A Cisco Ethernet switch connects the pieces of your network. Cisco catalyst switches offer intelligent switching - the ability to inspect packets of data and forward them to the device they are intended for. Cisco Catalyst switches offer greater network performance than hubs or basic switches that broadcast packets to every device.

The Cisco catalyst switch is an industry leader, featuring advanced technology and innovative products. Cisco Ethernet switches ensure high network availability, easy management tools, and advanced features. Some of the advantages of buying Cisco switches are:

1. Cisco network switches can integrate with an existing blade server.

2. There are plenty of design options and advanced features available.

3. A Cisco Catalyst switch includes many service and support options.

Action Steps
The best contacts and resources to help you get it done

Get a Cisco switch that integrates with your server

A Cisco blade switch can be installed on an IBM, HP or Dell server.

I recommend: The Cisco Systems Fiber Intelligent Gigabit Ethernet Switch Module is a Cisco fiber switch that connects to an IBM bladecenter server through internal ports. It includes module slots that enable gigabit SX fiber optic interfaces for external networks. The Cisco Catalyst Blade Switch 3030 for Dell PowerEdge servers has trunk failover, advanced security features and a simple user interface. For the HP Bladesystem, there is the Cisco Catalyst Blade Switch 3020 with 16 1GB downlinks and eight 1GB uplinks; 4 of which can be configured as fiber SX links.

Choose between stacked and modular switches

Several models of Cisco Ethernet switches are available for businesses of various sizes.

I recommend: The compact 8-port Catalyst 2940 is ideal for small offices and classrooms. There's a selection of 12-to-48-port stackable switches for small and mid-size organizations. The 4900 series is a rack optimized switch. The 4500 series is a modular mid-range switch with a chassis that supports a broad selection of line and supervisor cards. It's customizable with various chassis designs and power supplies. Individual components can be upgraded individually to reduce costs. View the full range of modular and standalone switches through Cisco's Comparison Guide.

Decide what kind of service and support you need

Cisco products carry a standard warranty as well as advanced support services. An entry level Cisco Ethernet switch can easily be installed and configured by a technically proficient employee. The web interface makes it easy to monitor and make changes.

I recommend: Subscribe to the Cisco Smart Foundation Service to get quick hardware replacement and access to phone support, online troubleshooting tools, and the Cisco knowledgebase. Cisco Network assistant has a user interface that allows IT staff to view and configure services across multiple switches. As you get into more advanced solutions, consider enrolling your IT staff in Cisco training through Cisco's online Networking Academy or Cisco learning partners like Global Knowledge or Element K. All have locations nationwide. You may also want to enlist help from a local certified Cisco partner.

Investigate advanced features

There are models of Cisco switches at all levels that support Power over Ethernet and other advanced features.

I recommend: Go to Cisco's Solution Designer to get assistance in finding a Cisco managed switch that meets your needs. If you require WAN support, advanced security modules, or support for video, IP telephony, or wireless, look at the Catalyst 6500. In addition to it's other features, its Virtual Switching Supervisor module presents a virtual switch that eliminates the need for a spanning tree and keeps links active until a failover occurs.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  All Cisco switches are VLAN Trunk Protocol (VTP) servers by default. In a large network, VTP can create excess traffic. At this point, the most advanced switches should be kept as VTP servers, and the others turned into a client.
