1 Switches that support only the SI cannot run the cryptographic image.


For guidelines and procedures on how to download the switch software from Cisco.com and to upgrade the switch, refer to the Cisco IOS Release 12.1(22)EA1 release notes.


Note After upgrading the switch to this release, you can only upgrade the switch through the CLI. You cannot upgrade the switch through the device manager.



Caution A bootloader upgrade occurs if you are upgrading Catalyst 2950 switches running Cisco IOS Release 12.1(9)EA1d or earlier to Cisco IOS Release 12.1(11)EA1 or later for both cryptographic and noncryptographic images. The bootloader can take up to 30 seconds to upgrade. Do not power cycle the switch while you are copying this image to the switch. If a power failure occurs when you are copying this image to the switch, call Cisco Systems immediately.

Installation Notes

You can assign IP information to your switch by using one of these methods:

Express Setup program, as described in the switch getting started guide. For information about this guide, see the "Getting Started Guide" section.

CLI-based setup program, as described in the switch hardware installation guide.

DHCP-based autoconfiguration, as described in the switch software configuration guide.

Manually assigned IP address, as described in the switch software configuration guide.

New Feature

This release offers a new embedded GUI referred to as the device manager. The device manager provides simplified management for a single switch. Its features, such as Smartports and color-coded graphs, make it easier to configure and monitor the switch. No special installation is required. After the switch is configured through the Express Setup program or through the CLI-based setup program, the device manager is accessible through a Microsoft Internet Explorer or Netscape Navigator browser session. For more information, refer to the device manager online help. For information on how to display the device manager, refer to the switch getting started guide. This guide is a new Catalyst 2950 document. For more information, see the "Getting Started Guide" section.

With the introduction of the device manager, note these considerations:

The Cluster Management Suite (CMS) software is not supported in this release and does not apply to the device manager. Disregard the CMS information in the Cisco IOS Release 12.1(22)EA1 release notes and in the Catalyst 2950 documentation, including the "Getting Started with CMS" chapter and the CMS instructions in the "Clustering Switches" chapter in the switch software configuration guide.

A new network management application referred to as Cisco Network Assistant replaces CMS. Network Assistant provides a comprehensive set of features for managing single and multiple devices, including switch clusters, through a GUI. This application must be downloaded from Cisco.com and be installed on your PC. It will be available from Cisco.com later in 2004. You can learn more about Network Assistant at this URL:

http://www.cisco.com/go/NetworkAssistant

Limitations and Restrictions

You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

These are the limitations and restrictions:

"Cluster Limitations and Restrictions" section

"Device Manager Limitations and Restrictions" section

Cluster Limitations and Restrictions

This release supports the same switch cluster compatibilities supported in Cisco IOS Release 12.1(22)EA1. However, you cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the CLI or the Cisco Network Assistant application. For information about Network Assistant, see the "New Feature" section.


Note Disregard the CMS information in the "Clustering Switches" chapter in the switch software configuration guide because they do not apply to this release or to the device manager.


Device Manager Limitations and Restrictions

These limitations and restrictions apply to the device manager:

This release supports the same switch cluster compatibilities supported in Cisco IOS Release 12.1(22)EA1. However, you cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the CLI or the Cisco Network Assistant application. For information about Network Assistant, see the "New Feature" section.


Note Disregard the CMS information in the "Clustering Switches" chapter in the switch software configuration guide because they do not apply to this release or to the device manager.


After upgrading the switch to this release, you can only upgrade the switch through the CLI. You cannot upgrade the switch through the device manager.

Important Notes

This section describes important information related to the device manager.

We recommend this browser setting to speed up the time to display the device manager from Microsoft Internet Explorer.

From Microsoft Internet Explorer:

1. Choose Tools > Internet Options.

2. Click Settings in the "Temporary Internet files" area.

3. From the Settings window, choose Automatically.

4. Click OK.

5. Click OK to exit the Internet Options window.

The HTTP server interface must be enabled to display the device manager. By default, the HTTP server is enabled on the switch. Use the show running-config privileged EXEC command to see if the HTTP server is enabled or disabled.

Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:

 
Command
Purpose

Step 1 

configure terminal

Enter global configuration mode.

Step 2 

ip http authentication {enable | local | tacacs}

Configure the HTTP server interface for the type of authentication that you want to use.

enable—Enable password, which is the default method of HTTP server user authentication, is used.

local—Local user database, as defined on the Cisco router or access server, is used.

tacacs—TACACS server is used.

Step 3 

end

Return to privileged EXEC mode.

Step 4 

show running-config

Verify your entries.

The device manager uses the HTTP protocol (the default is port 80) and the default method of authentication (the enable password) to communicate with the switch through any of its Ethernet ports and to allow switch management from a standard web browser.

If you change the HTTP port, you must include the new port number when you enter the IP address in the browser Location or Address field (for example, http://10.1.126.45:184 where 184 is the new HTTP port number). You should write down the port number through which you are connected. Use care when changing the switch IP information.

If you are not using the default method of authentication (the enable password), you need to configure the HTTP server interface with the method of authentication used on the switch.

Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:

 
Command
Purpose

Step 1 

configure terminal

Enter global configuration mode.

Step 2 

ip http authentication {enable | local | tacacs}

Configure the HTTP server interface for the type of authentication that you want to use.

enable—Enable password, which is the default method of HTTP server user authentication, is used.

local—Local user database, as defined on the Cisco router or access server, is used.

tacacs—TACACS server is used.

Step 3 

end

Return to privileged EXEC mode.

Step 4 

show running-config

Verify your entries.

If you use Internet Explorer Version 5.5 and select a URL with a nonstandard port at the end of the address (for example, www.cisco.com:84), you must enter http:// as the URL prefix. Otherwise, you cannot launch the device manager.

Open Caveats

These are the open caveats for the device manager:


Note Refer to the Cisco IOS Release 12.1(22)EA1 release notes for the open Cisco IOS caveats, which also apply to this release.
