When You Are Done

Set Up the Switch for the First Time

Prerequisite

To set up the switch for the first time, follow the procedure described in the Getting Started Guide for the Catalyst Express 500 Switches.


These are the configuration settings that you can set during initial setup:

Network Settings

Optional Settings

Network Settings

The network settings enable the switch to operate with its standard default settings and to be managed through the device manager. You must apply these settings to access and to take advantage of the monitoring, troubleshooting, and configuration features on the switch. Otherwise, the switch cannot be managed, and switch monitoring is limited to only its physical LEDs.

Management Interface (VLAN ID)

The ID of the management VLAN through which the switch will be managed.

The management VLAN ID can be from 1 to 1001. The default ID is 1. The default name for the management VLAN is default.

Note Make sure that the switch and your network management station are in the same VLAN. Otherwise, you cannot manage the switch from your management station. If they are in different VLANs, a router or Layer 3 switch is needed to communicate between VLANs.

The management VLAN is the broadcast domain where management traffic is sent between specific users or devices. It provides broadcast control and security for management traffic that should only be limited to a specific group of users (such as the administrators of your network). It also ensures secure, administrative access to all devices in the network at all times.

For more information about management VLANs and about VLANs in general, see the "VLAN Types" section on page 3-14.

IP Assignment Mode

The IP assignment mode determines if the switch IP information will be manually assigned (static) or be automatically assigned by a Dynamic Host Configuration Protocol (DHCP) server. The default is Static.

We recommend that you select Static and manually assign the IP address for the switch. You can then use the same IP address whenever you want to access the device manager.

If you select DHCP, the DHCP server automatically assigns an IP address, subnet mask, and default gateway to the switch. As long as the switch is not restarted, the switch continues to use this information, and you can use the same IP address to access the device manager.

Note If you manually assign the switch IP address and your network uses a DHCP server, make sure that the IP address that you give to the switch is not within the range of addresses that the DHCP server will automatically assign to other devices. This prevents IP address conflicts between the switch and another device.

IP Address

The IP address is a unique identifier for the switch in a network. The format is four numbers separated by periods. Each number can be from 0 to 255.

This field is enabled only if the IP assignment mode is Static.

Note Make sure that the IP address that you assign to the switch is not being used by another device in your network.

The IP address and the default gateway cannot be the same.

The IP addresses in the 10.0.0.0 network cannot be configured on the switch.

Subnet Mask List

The subnet mask is the network address that identifies the subnetwork (subnet) to which the switch belongs. Subnets segment the devices in a network into smaller groups. The default is 255.255.255.0.

This setting is enabled only if the IP assignment mode is Static.

Default Gateway

The IP address for the default gateway. A gateway is a router or a dedicated network device that enables the switch to communicate with devices in other networks or subnetworks. The IP address should be part of the same subnet as the switch IP address.

If all of your devices are in the same network and a default gateway is not used, you do not need to enter an IP address in this field.

This setting is enabled only if the IP assignment mode is Static.

Note You must specify a default gateway if your network management station and the switch are in different networks or subnetworks. Otherwise, the switch and your network management station will not be able to communicate with each other.

The IP address and the default gateway cannot be the same.

Username

The name of a user who is authorized to access the device manager. The name can have up to 64 alphanumeric characters and is not case sensitive. The name cannot contain a ?, a space, or a tab.

You must enter a username if you enter a password. We recommend that you provide a username-and-password pair to the switch to secure access to the device manager.

After initial setup, you can add, delete, or modify username-and-password pairs from the Users and Passwords window on the device manager. To display this window, choose Configure > Users and Passwords from the device manager menu. For more information, see the "Control Access to the Switch" section on page 3-11.

Password

The password for the switch can have up to 25 alphanumeric characters, can start with a number, is case sensitive, and allows embedded spaces. The password cannot contain a ? or a tab and does not allow spaces at the beginning or end.

We recommend that you provide a username-and-password pair to the switch to secure access to the device manager.

After initial setup, you can add, delete, or modify username-and-password pairs from the Users and Passwords window on the device manager. To display this window, choose Configure > Users and Passwords from the device manager menu. For more information, see the "Control Access to the Switch" section on page 3-11.


Optional Settings

The optional settings identify and synchronize the switch so that it can be managed properly. The switch clock is automatically synchronized with the system clock on your network management station. You can manually set the system clock settings if the switch should have different time settings.

Host Name

A name for the switch. The name can have up to 31 alphanumeric characters. The name cannot contain a ?, a space, or a tab. The default is Switch.

We recommend entering either the name, location, or IP address of the switch to help identify the switch during monitoring or troubleshooting.

System Date

The date that the switch automatically reads from the network management station. You can also manually set the date.

System Time

The time that the switch automatically reads from the network management station. You can also manually set the time.

Time Zone

The time zone that the switch automatically reads from the network management station. You can also manually set the time zone.

Daylight Saving Time

The check box is automatically enabled only when the selected time zone is in U.S., Europe, or Australia.

Installation Guidelines

When deciding where to place the switch, be sure to observe these requirements:

Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures.

Clearance to front and rear panels is such that

Airflow around the switch and through the vents is unrestricted.

Front-panel LEDs can be easily read.

Access to ports is sufficient for unrestricted cabling.

AC power cord can reach from the AC power outlet to the connector on the switch rear panel.

Temperature does not exceed 113°F (45°C), humidity does not exceed 85 percent, and altitude at the installation site is not greater than 10,000 feet (3049 m).

If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

For copper Ethernet ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).

For SFP module cable lengths, see Table A-2 and the documentation that shipped with the module.

Rack-Mounting

Position the mounting bracket and screw on the side of the switch. Tighten the screw with a screwdriver. Repeat on the opposite side.

Insert the switch into the 19-inch rack, and align the bracket in the rack. Use either the 10-32 pan-head screws or the 12-24 pan-slotted screws to secure the switch in the rack. Use the supplied black Phillips machine screw to attach the cable guide to either bracket.

Desktop-Mounting

Place the switch upside-down on a flat surface. Attach the four rubber pads to the recessed areas on the bottom of the switch. Place the switch on a desktop near an AC power source.

If you are stacking switches, make sure that the mounting feet of the upper switch align with the recesses of the lower switch. Do not stack more than four units high.

Wall-Mounting

Position the mounting bracket and screw on the side of the switch, rotated 90-degrees from the view shown in the rack-mounting illustration. Tighten the screw with a screwdriver. Repeat on the opposite side.

Mount the switch on the wall with the front panel facing up. For the best support of the switch and cables, make sure that the switch is attached securely to wall studs or to a firmly attached plywood mounting backboard. Screws for wall-mounting are not provided.

Display the Device Manager

Prerequisite

Make sure that you meet the requirements described in the "System Requirements" section on page 1-10.


You can display the device manager (Figure 1-3) from anywhere in your network through a web browser such as Microsoft Internet Explorer or Netscape Navigator.

Follow these steps to display the device manager:

1. Open a web browser session on your PC or workstation.

2. Enter the switch IP address in the web browser, and press Enter. The device manager page appears.

3. Use the device manager to perform basic switch configuration and monitoring. See the device manager online help for information.

For more advanced configuration, download and run the Cisco Network Assistant (see the "Cisco Network Assistant" section on page 1-12) application.

We recommend running the cryptographic software image on the switch and using the option to run a secured session with the switch. See the "Secured Sessions with the Switch" section for information on how to ensure that your device manager session is protected from unauthorized access.

Secured Sessions with the Switch

The switch uses the Secure Sockets Layer (SSL) protocol to secure the HTTP communications between the switch and your network management station. When you attempt to display the device manager, this protocol:

Authenticates the web-based connection between the switch and your network management station

Encrypts and decrypts the information exchanged between the switch and your network management station to protect the information from unauthorized access over the Internet

SSL is enabled by default on the switch. It is available only on the cryptographic version of the switch software image.

More information about secured sessions is available from the device manager online help.

When You Are Done

Use the features that are described in Chapter 3, "Customization" and Chapter 4, "Monitoring" to configure and to monitor the switch in your network.
