As maintenance releases and future software releases become available, they will be posted to Cisco.

Cisco IOS Release The dual front ends are not redundant interfaces, and only one port of the pair is active. These sections describes the hardware and software requirements for using the device manager:. The device manager verifies the browser version when starting a session to ensure that the browser is supported.

Note The device manager does not require a plug-in. You cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the command-line interface CLI or the Network Assistant application. When creating a switch cluster or adding a switch to a cluster, follow these guidelines:. For example, if the command switch is a Catalyst switch, all standby command switches must be Catalyst switches. For additional information about clustering, see the "Clustering Switches" chapter of the software configuration guide.

These are the procedures for downloading software, download catalyst 2960 ios. Before downloading software, read this section for important information:.

A subdirectory contains the files needed for web management. The image is stored on the system board flash device flash:.

You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version, download catalyst 2960 ios.

You also can use the dir filesystem: privileged EXEC command to see the directory names of other software images that you might have stored in flash memory, download catalyst 2960 ios. The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager.

You must use the combined tar file to upgrade the switch through the device manager. Catalyst image file and device manager files. Catalyst cryptographic image download catalyst 2960 ios and device manager files. This image has the Kerberos and SSH features.

You can upgrade switch software by using the device manager or Network Assistant. For detailed instructions, click Help. Note When using the device manager to upgrade your switch, do not use or close your browser session after the upgrade process begins.

Wait until after the upgrade process completes. Before upgrading your switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly in your network.

See Product Bulletin for more information:. You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command. We recommend that you download the tar file from Cisco. Download catalyst 2960 ios can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command, download catalyst 2960 ios.

This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image. If you have a SmartNet support contract, go to this URL, and log in to download the appropriate files:. To download the image for a Catalyst switch, click Catalyst software.

To obtain authorization and to download the cryptographic software files, click Catalyst 3DES Cryptographic Software, download catalyst 2960 ios. For more information, refer to Appendix B in the software configuration guide for this release.

For more information about assigning an IP address and default gateway to the switch, refer to the software configuration guide for this release. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:. Directory and image names are case sensitive. This example shows how to download an image from a TFTP server at For recovery procedures, see the "Troubleshooting" chapter in the software configuration guide for this release.

These sections describe the new supported hardware and the new software features provided in this release:. For a list of all supported hardware, see the "Hardware Supported" section.

This release is the first software release for the Catalyst switch. For a detailed list of key features for this software release, refer to the Catalyst Switch Software Configuration Guide.

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 download catalyst 2960 ios changes to the switch hardware or software.

Unless otherwise noted, these limitations apply to the Catalyst switches:. The workaround is to reconfigure the static IP address. The problem is observed only when the switch is receiving frames. The workaround is to configure the port for 10 Mbps and half duplex or to connect a hub or a nonaffected device to the switch. The workaround is to enter the no switchport block unicast interface configuration command on that specific interface.

There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. The workaround is to ensure that the ports on the standby cluster members are not in the spanning-tree blocking state. To verify that these ports are not in the blocking state, see the "Configuring STP" chapter in download catalyst 2960 ios software configuration guide.

The workaround is to use rate limiting on Download catalyst 2960 ios traffic to prevent a denial of service attack from occurring, download catalyst 2960 ios.

These APs should be discovered as Cisco pre-standard devices. The workaround is to power the AP by using an AC wall adaptor. MAC addresses are manually or automatically deleted when a topology change occurs or when port security or an Because learning is restricted on No workaround is necessary.

The workaround is to reduce the number of multicast routes and IGMP snooping groups to less than the maximum supported value. It is not applied to packets that are forwarded download catalyst 2960 ios software. Hence, with multicast routing enabled, the first few packets are sent from a port even when IGMP filtering is set to deny those groups on that port. The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic.

The workaround is to enter clear ip mroute privileged EXEC command on the interface. The ratio of buffer size to threshold level should be greater than 10 to avoid disabling the queue. The workaround is to choose compatible buffer sizes and threshold levels. Instead, the switch uses shaped round robin SRR as the queuing mechanism.

The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and download catalyst 2960 ios queuing mechanism supported on each platform might be different. Valid However, you cannot create and manage switch clusters through the device manager, download catalyst 2960 ios.

For information about Network Assistant, see the "New Features" section. The workaround is to click Yes when you are prompted to accept the certificate. These sections describe the important notes related to this software release for the Catalyst switches:.

Click Settings in the "Temporary Internet files" area. From the Settings window, choose Automatically. Click OK. Click OK to exit the Internet Options window. By default, the HTTP server is enabled on the switch. Configure the HTTP server interface for the type of authentication that you want to use. 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 download catalyst 2960 ios authentication the enable passwordyou need to configure the HTTP server interface with download catalyst 2960 ios method of authentication used on the switch.

Download catalyst 2960 ios, you cannot launch the device manager. Cisco IOS may permit arbitrary code execution after exploitation of a heap-based buffer overflow vulnerability.
