Overview

The Catalyst Express switches (Table 1-1) provide networking for businesses with up to 250 employees. These switches provide network services to support data, voice, and mobile network demands. The services ensure transmission quality and reliability for data and voice traffic. They also provide security to protect against network attacks.

You can simply install the switch and allow it to operate without any further management intervention. You can also take advantage of the embedded software features—tools to quickly and easily set up, customize, monitor, and troubleshoot the switch—to optimize your use of the switch.

Figure 1-1 is an example network using Catalyst Express switches. Devices outside the dotted line are network users and network resources, such as servers and printers. Devices within the dotted line are switches, routers, and access points that enable communication between network users and provide access to network resources.

Figure 1-1 Catalyst Express Network Example

Any of the Catalyst Express switch models can be Switches A, B, C, and D in this network. To take full advantage of the different switch models, use the model that is designed for the type of connections that you require.

For example, use the Catalyst Express 500G-12TC for Switches A and B. This model has the most Gigabit Ethernet ports, and it is best suited to providing 1000-Mbps connections between switches and to servers.

Use either the Catalyst Express 500-24TT or the Catalyst Express 500G-12TC for Switches C and D. These switches are designed to provide high-speed (up to 100 Mbps and 1000 Mbps, respectively) connections to network users.

If you need to connect PoE devices to your network, use the Catalyst Express 500-24LC and the Catalyst Express 500-24PC. These switches can provide power to up to 4 or up to 24 PoE devices, respectively.

PoE connections from the switch provide both power and network access to PoE-capable devices, such as IP phones and access points. PoE devices can receive up to 15.4 W of power from their connections to the switch. PoE also helps reduce cabling costs. You can place PoE devices where power outlets are not available or are not convenient.

Multiple connections between the switches ensure that users maintain network access if any of the switches becomes overused or unavailable.

A network administrator can manage the network onsite or remotely through the device manager GUI (embedded in the Catalyst Express switches), through Cisco Network Assistant, or through a Simple Network Management Protocol (SNMP)-based network management application. For more information about managing the switches, see the "Device Manager GUI" section and the "Switch Management Options" section.

For more information about how to optimize the connections in a Catalyst Express network, see the "Optimize Ports through Smartports Port Roles" section on page 3-2.

Software Features

These are the switch software features and the benefits that they provide. You can configure these features through the device manager GUI (see the "Device Manager GUI" section). For details on these features, see the chapters on Customization, Monitoring, and Troubleshooting.


Note For enhanced switch features that are available only through Network Assistant and not through the device manager GUI, see the "Cisco Network Assistant" section.


Express Setup

Initial setup only requires IP information for first-time switch configuration.

Quick IP information updates if you relocate the switch to a different network.

Date and time settings automatically synchronized between the switch and the network management station.

Dynamic Host Configuration Protocol (DHCP) automatically assigns the switch an IP address, a default gateway, and a subnet mask from a DHCP server.

Troubleshooting

General switch diagnostic test detects problems on the switch. Link diagnostic test detects cable-related issues on a specified port.

General switch and link diagnostic reports describe problems detected on the switch and its ports and list recommended actions to resolve each problem.

Monitoring

Alert LED notifies that one or more problems were detected on the switch.

Alert Log lists all problems detected on the switch, including a timestamp of the most recent detection of each problem.

Graphical front panel display, LEDs, gauges, graphs, and animated indicators show switch and port status, utilization, and error percentages, and temperature and fan status.

Port status and statistics tables display port operating status and the statistics for data being received and sent on each port.

Customization

Smartports port roles optimize switch ports according to their attached devices. Security and quality of service (QoS) benefits are built into the port roles.

Secure Socket Layer (SSL) protocol authenticates and encrypts communications to the switch device manager GUI. (Requires the cryptographic version of the switch software available from the software download page on Cisco.com.)

Username-and-password pair configuration for controlling switch access.

VLANs for grouping network users according to functions, teams, or applications, and regardless of the physical location of the network users. The switch supports up to 32 VLANs.

VLAN support includes these features:

Spanning Tree Protocol (STP) prevents network loops from developing and provides a redundant path if the active path becomes unavailable.

Internet Group Management Protocol (IGMP) snooping reduces duplicate and excess traffic on the network.

EtherChannels for bundling multiple Fast Ethernet or Gigabit Ethernet ports into a single logical link to create a higher bandwidth link between the switch and another switch.

Simple Network Management Protocol (SNMP) versions 1, 2C, and 3 to allow a remote network management station to access, monitor, and control the switch.


Device Manager GUI

The device manager is a graphical device management tool for configuring, monitoring, and troubleshooting the switch (Figure 1-3).

It simplifies configuration tasks with features such as Express Setup and Smartports for quickly setting up the switch and its ports. It uses graphical, color-coded displays such as the switch front panel view, graphs, and animated indicators to simplify monitoring tasks. It provides alert and diagnostic tools to help you identify and solve networking problems.

Additional details about the device manager and procedures on using the device manager windows are available from the device manager online help (Figure 1-4).

You can display the device manager from anywhere in your network through a web browser such as Microsoft Internet Explorer or Netscape Navigator. For information on how to display the device manager, see the "Display the Device Manager" section.
