Note In Cluster Management displays, Internet Explorer versions 4.01 and 5.0 might not display edge devices that are not connected to the command switch. Other functionality is similar to that of Netscape Communicator.


Installing the Required Plug-In

A browser Java plug-in is required to access the HTML-based Cluster Management Suite (CMS). Download and install the plug-in before you start CMS.

If the Java applet does not initialize after you have installed the plug-in, open the Java Plug-in Control Panel (Start > Programs > Java Plug-in Control Panel), and verify the following setting:

In the Proxies tab, verify that Use browser settings is checked and that no proxies are enabled.

If you are running McAfee VirusScan on Windows 2000 and the plug-in takes a long time to load, you can speed up CMS operation by disabling the VirusScan Internet Filter option, the Download Scan option, or both.

From the Start menu, disable the options by selecting Start > Programs > Network Associates > Virus Scan Console > Configure.

or

From the task bar, right-click the Virus Shield icon, and in the Quick Enable menu, disable the options by deselecting Internet Filter or Download Scan.

Windows 2000, Windows 95, Windows 98, and Windows NT 4.0 Users

These Java plug-ins are supported on the Windows platform:


Caution To avoid performance and compatibility issues, do not use Java plug-ins later than Java
plug-in 1.3.0.

Java plug-in JRE 1.2.2_05

If you start CMS without having installed the required Java plug-in, the switch automatically detects this. If you are using a supported Internet Explorer browser, it automatically downloads and installs the plug-in. If you are using a supported Netscape browser, the browser displays a Cisco.com (previously Cisco Connection Online [CCO]) page that contains the Java plug-in and installation instructions. If you are using Windows 2000, Netscape Communicator might not detect the missing Java plug-in. You can download the plug-in from one of these URLs:

If you have a SmartNet support contract, download the plug-in from this URL:

http://www.cisco.com/cgi-bin/tablebuild.pl/java

If you do not have a SmartNet contract, download the plug-in from this URL:

http://www.cisco.com/pcgi-bin/tablebuild.pl/java

Creating Clusters with Different Releases of IOS Software

Some versions of the Catalyst 2900 and 3500 XL software do not support clustering, and other versions do not support the features in this release. To ensure that all cluster switches are operating with the same level of software, we recommend that you upgrade all cluster switches to IOS Release 12.0(5.1)WC(1) or later.

If you have a cluster with switches that are running different versions of IOS software, changes on the latest release might not be reflected on switches running the older versions. For example, if you start Visual Switch Manager (VSM) on a switch running IOS Release 11.2(8)SA6, the windows and functionality can be different from a switch running IOS Release 12.0(5)WC2 or later.


Note If your command switch is a Catalyst 2900 or 3500 XL switch running Cisco IOS
Release 12.0(5.1)XW or earlier, a Catalyst 2950 switch will show as an unknown device in Cluster Manager. In this case, you will need to use Visual Switch Manager (VSM) to manage the Catalyst 2950 switch.


Features

For a detailed list of key features for this software release, refer to the Catalyst 2950 Desktop Switch Software Configuration Guide.

Limitations and Restrictions

Review this section before you begin working with the switches. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

Connecting to the Cisco RPS 300

The Catalyst 2950 switches support the Cisco RPS 300 Redundant Power System.


Note The Catalyst 2950 switches do not support the Cisco 600W Redundant Power System (RPS).


Port Configuration Conflicts

Certain combinations of port features create configuration conflicts (see Table 4). If you try to enable incompatible features, CMS issues a warning message, and you cannot make the change. Reload the page to refresh CMS.

In Table 4, No means that the two referenced features are incompatible and should not both be enabled; Yes means that both can be enabled at the same time and will not cause an incompatibility conflict.

Using Commas in CMS

Host names and Domain Name System (DNS) server names that contain commas on a cluster command switch, member switch, or candidate switch can cause CMS to behave unexpectedly. You can avoid this instability in the interface by not using commas in host names or DNS names. Also, do not enter commas when entering multiple DNS names in the IP Configuration tab of the IP Management window in CMS.

SPAN Limitations

When using the Switched Port Analyzer (SPAN) feature, the monitoring port receives copies of transmitted and received traffic for all monitored ports. If the monitoring port is 50 percent oversubscribed for a sustained period of time, it will probably become congested. One or more of the ports being monitored might also experience a slowdown.

Compatibility with the CiscoWorks2000 RME Suite

When using the Software Image Management (SWIM) application in the Resource Manager Essentials (RME) suite of the CiscoWorks2000 product family to perform automated system software and boot loader upgrades, you should note the following:

Catalyst 2950 switches require IOS Release 12.0(5.2)WC(1) or later.

Catalyst 2900 series XL switches require IOS Release 11.2(8)SA4 or later and RME version 2.1
or 2.2.

Catalyst 3500 series XL switches require IOS Release 11.2(8.1)SA6 or later and RME version 2.2.

Ethernet Frame Size Support

The Catalyst 2950 switches support standard-size Ethernet frames (64 to1518 bytes).


Note Frame sizes larger than 1518 bytes are not supported.


Documentation Notes

All documentation for this release, except for these release notes, is provided on the Catalyst 2950 Desktop Switch Documentation CD.

Documentation CD

To view the contents of this documentation CD, double-click the index.htm file. Your browser will launch, and you will be able to select and view the documents on the CD.

If your PC is set to automatically launch CDs, the index page opens when you insert the CD or when you click the CD icon. If you need more information about how to set your PC to automatically launch CDs, consult your PC operating system documentation or systems administrator.


Note From the .pdf files on the Catalyst 2950 Desktop Switch Documentation CD, clicking a link from the last page of the Table of Contents sometimes opens the Index instead of the section that you want. Another way to navigate to a section is to click a heading under the Bookmarks tab in the left window. To display subheadings, click the plus sign (+) next to the heading.


Correction to the Hardware Installation Guide

This information corrects an error in the Catalyst 2950 Desktop Switch Hardware Installation Guide.


Caution Do not mount a Catalyst 2950 switch on a wall. Do not follow the mounting instructions as shown in Figure 2-6 on page 2-13 and Figure 2-7 on page 2-14 in the Catalyst 2950 Desktop Switch Hardware Installation Guide.

Correction to the Software Configuration Guide

This information corrects an error in Chapter 5, "Creating and Managing VLANs," of the Catalyst 2950 Desktop Switch Software Configuration Guide. In the "CLI: Configuring CoS Priority Queues" section, the CLI procedure to configure the CoS priority queues is described. The CLI command for Step 4 should be show wrr-queue cos-map instead of show cos-map.

Caveats

Open Caveats

This section describes possible unexpected activity by IOS Release 12.0(5)WC2:

CSCdt24814 (formerly CSCdt2481)

Source-based distribution port group does not share the broadcast with all the group members. When the destination of the packets is a broadcast or unknown unicast or multicast, the packets are forwarded only on one port member of a port group, instead of being shared among all members of the port group.

There is no workaround.

CSCds72421

If you shut down the management VLAN on VLAN1 on a Catalyst 2950 switch, set the management VLAN to 999, and then again use the shutdown command to shut down VLAN1, the IP address of VLAN 999 does not appear in the show cdp neighbor detail command display on a connected device.

The workaround is to reboot the switch.

CSCdt48011

There are two problems that occur when the Catalyst 2950 switch is in transparent mode:

If the switch is a leaf switch, any new VLANs added to it are not propagated upstream through VTP messages. As a result, the switch does not receive flooded traffic for that VLAN.

If the switch is connected to two VTP servers, it forwards their pruning messages. If the switch has a port on a VLAN that is not requested by other servers through their pruning messages, it does not receive flooded traffic for that VLAN.

There is no workaround.

CSCds20365

Internal loopback in half-duplex mode causes input errors. We recommend that the PHY is configured to operate in full duplex before setting internal loopback.

There is no workaround.

CSCdt83016

When the Catalyst 2950 switch boots up without being configured, it prompts the user with a configuration dialog. The switch allows the user to skip the dialog and to enable traps without configuring a community string. If the host trap receiver is configured without defining the community strings, when the switch attempts to generate a trap, it fails and displays an error message.

The workaround is to follow the configuration sequence by creating a community string before configuring traps for the host.

CSCdr96565

Aging of dynamic addresses does not always occur exactly after the specified aging time elapses. It might take up to three times this time period before the entries are removed from the table.

There is no workaround.

CSCdt74555

When a MAC address is learned on a member of a port group created between a Catalyst 2950 and Catalyst 2900 or 3500 XL switch, the same MAC address gets deleted and relearned on another port member of the port group on the 2900 or 3500 XL switch. As a result, a real-time diagnostic message reports this address relearning behavior. The symptom does not affect the connectivity and is informational only.

The workaround is to upgrade the image on the Catalyst 2900 or 3500 XL switch to the IOS
Release 12.0(5.1)WC(1) or later.

CSCdt48569

If any VLAN other than VLAN1 is configured as the management VLAN, the switch reports an incorrect shut down for VLAN1. VLAN1 is not administratively down even though the running configuration has shut down in VLAN1.

There is no workaround.

CSCdt48351

The usage of the c2950BandwidthUsage Management Information Base (MIB) always shows zero, instead of displaying the current bandwidth usage statistics.

There is no workaround.

CSCdt82729

If you launch the VMPS Configuration window from the device popup menu in Visual Switch Manager (VSM), it displays incorrect information.

The workaround is to not launch the VMPS Configuration window from the device popup menu, as VLAN Membership Policy Server (VMPS) is not supported on the Catalyst 2950 switches.

CSCdt82712

If you launch VSM for a member switch, right-click the switch image to activate the device popup menu, and then left-click it to deactivate the popup menu, or if you select a port and deselect it, the Cluster Management icon on the toolbar is disabled and cannot be used to launch Cluster Management.

The workaround is to select Cluster > Cluster Management from the Cluster Management menu bar.

CSCds68177

The UniDirectional Link Detection (UDLD) protocol does not always detect a unidirectional link when there is a loop between the TX and RX strands on the same port (TX/RX loop condition).

This is an intermittent problem, and there is no workaround.

CSCds58369

If the switch gets configured from the dynamic IP pool, a duplicate or different IP address might be assigned.

The workaround is to make sure that the DHCP server contains reserved addresses that are bound to each switch by the switch hardware address so that the switch does not obtain its IP address from the dynamic pool.

CSCdt49955

CMS dialogue windows can display two list selection boxes with Add and Remove buttons between them. If you press the Shift key on the keyboard at the same time as either the Add or Remove button, sometimes an exception error occurs. The exception error appears only inside the Java console window and is not displayed by CMS. As a result of the exception error, the Add or Remove buttons might not function correctly. If you continue to click them, multiple entries are added to the available or selected list.

The workaround is to not hold down the Shift key when clicking Add or Remove.

CSCdp67822

Cluster Management Suite requires a Java plug-in from Sun Microsystems. If you are using Internet Explorer and you disable Java plug-ins by using the Java Plug-In Control Panel, the initial Splash screen shows that the plug-in and Java are enabled, but Internet Explorer fails.

The workaround is to not disable Java plug-ins on the Java Plug-In Control Panel.

CSCdp61365

If you right-click a device that is near the edge of the browser window, the second-level menu of the device pop-up menu might not display.

The workaround is to right-click again on the device until the pop-up menu displays correctly.

CSCdp82224

The Cluster Manager System Time Management window supports the configuration of the Network Time Protocol (NTP) and system time. When you make changes on this window from a command switch, Java propagates the changes to all cluster members. A conflict can arise if you configure NTP and also use the Set Daylight Saving Time and Set Current Time tabs.

To avoid a possible conflict, either set the system time for the entire cluster on the command switch, or configure NTP on the command switch to use an NTP server to provide time to the cluster. Do not use both methods at the same time.

CSCdp82354

You can use Cluster Manager to configure an Hot Standby Router Protocol (HSRP) standby group and bind it to a cluster. However, you cannot use Cluster Manager to configure more than one standby group. If you want to configure more than one standby group, use the command-line interface (CLI).

CSCdp70389

When changing the management VLAN on a cluster with command-switch redundancy enabled, the cluster can break if HSRP is configured on any of the cluster members in the new management VLAN.

The workaround is to not change the management VLAN to a VLAN where a member is configured as part of a standby group.

CSCdp85954

Root guard is inconsistent when configured on a port that is in the STP blocked state at the time of configuration.

CSCdp49419

HSRP does not support a virtual MAC address entry or a built-in address (BIA) for a cluster.

CSCdp97517

All members of an HSRP standby group must be cluster members.

CSCdp30543

If the storm control filter is enabled for unicast, multicast, or broadcast traffic and the rising threshold is reached, all traffic on the port is filtered. No unicast, multicast, or broadcast traffic is forwarded from the port.

CSCdp87748

Cisco IOS does perform some checks on entered IP addresses. For example, it does not allow the broadcast address to be entered. However, it does not check for the broadcast address on the same subnet as the HSRP Versatile Interface Processor (VIP) or the management VLAN IP address. This means that you could configure HSRP with a virtual IP address that is the same as the network broadcast address.

There is no workaround.

CSCdp75220

If you use the command switch DNS server name to start CMS for a member that is running an earlier software release, CMS might not display the switch image, or it might display the command switch image. This can also occur when a standby group is configured for a cluster and you access CMS by entering the command-switch IP address and not the virtual IP address.

The workaround is to always use the command-switch IP address to access CMS. If a standby group is configured for a cluster, always use the virtual IP address to access CMS.

CSCdp85928

CMS can behave unexpectedly if host names or DNS server names that it processes contain commas. This means that host names or DNS server names on a cluster command switch, member, or neighbor can cause instability in the HTML interface.

The workaround is to not include commas in host names or DNS server names in CMS.

CSCdp62807

If you click the list of switches in CMS and press the Page Down key on the keyboard, the entire list moves to the bottom of the window. This only happens with Windows NT.

The workaround is to collapse the list into a single icon, which returns the list to the top of the window.

CSCdp89945

In VSM, you cannot see the individual menu items when you right-click the chassis image to display the device pop-up menu.

The workaround is to right-click another part of the chassis image to display the device pop-up menu.

Resolved Caveats

These problems were resolved in Cisco IOS Release 12.0(5)WC2:

CSCdv35805

If you are copying the configuration file using ciscoConfigCopyMIB from a Catalyst 2950 switch by using Simple Network Management Protocol (SNMP) manager, the switch no longer reloads the configuration.

CSCdv16305

A broadcast storm no longer occurs when two 100BASE-FX ports on a Catalyst 2950 switch are connected to the 100BASE-FX ports on another Catalyst 2950 switch if these ports are in trunk mode and one of the ports is administratively down.

CSCds72421

If the management VLAN is changed to any other VLAN from VLAN 1 and VLAN 1 is shut down, the IP address configured in the new management VLAN now appears in the show cdp neighbor detail privileged EXEC command.

CSCdt57346

When you use the show rmon history EXEC command, the value for the collision is now unique for each sample.

CSCdu09410

The ifSpeed of the interfaces now reports the default value of the visible bandwidth when the link is down and reports the configured and assigned values when the link is up.

CSCdu37367

The clear counters and clear counters fastethernet <port> interface commands now clear the port security counters. These commands also clear the other counters for the interface.

CSCdu49099

Changing the VLAN Trunking Protocol (VTP) mode to transparent no longer causes a virtual type terminal session to lock up when executing commands, such as the show vlan privileged EXEC command, that require access to the VLAN- and VTP-related data.

In addition, ports that were shut down during VTP mode change now come back up automatically when VTP is stable.

CSCdu67033

The output count displayed by the show interface privileged EXEC command output now displays correctly when the count is greater than 4,294,967,296 packets.

CSCdu88701

When performing an snmpwalk SNMP operation on the dot1dTpFdbTable (1.3.6.1.2.1.17.4.3), the response no longer omits all entries of show mac in the display in which the first byte of the host MAC address is greater than 0x00.

CSCdv21552

High CPU utilization no longer occurs when a switch boots with a VLAN (without an IP address) in the shutdown state while another active VLAN has an IP address.

CSCdv41819

Enabling spanning-tree UplinkFast no longer causes brief spanning-tree loops if the configuration message from the root switch of the spanning tree ages out.

CSCdt83016

When the Catalyst 2950 switch boots up without being configured, it prompts the user with a configuration dialog. The switch allows the user to skip the dialog and to enable traps without configuring a community string. If the host trap receiver is configured without defining the community strings, when the switch attempts to generate a trap, it fails and displays an error message.

The workaround is to follow the configuration sequence by creating a community string before configuring traps for the host.

CSCdt04001

When you change the privilege level for interface on the Catalyst 2950 switches, you can execute commands with the newly configured privilege level. The switch now saves the arguments associated with the command, and after a reload, the configured commands are executable.

CSCdt24089

If the Catalyst 2950 switch contains multicast addresses, the MIB walk of Dot1dTpFdbEntry no longer consumes excess CPU cycles on the switch.

CSCdt68204

If you continuously ping a switch from a PC and the links from the switch to the network are brought down, when the link from the switch to the network is restored, pinging now resumes.

CSCdt59751

The no snmp-server enable traps snmp [authentication] global configuration command is not supported by this software release.

CSCdu87426

The 100BASE-FX ports in a Fast EtherChannel port group no longer loop packets when the connected device resets or reloads.

CSCdv46396

If the switch has a MAC address of 00xx.xxxx.xxxx, it no longer halts after the no port security and clear mac-address-table secure commands are entered.

CSCdv47498

The SNMP walk of the Dot1dTpFdbTable no longer causes the switch to halt and put an SNMP CPU HOG error message in the logging buffer.

CSCdv51153

SNMP MIB variables etherStatsEntry does not display any values in Cisco IOS Release 12.0(5)XU or later.

There is no workaround.

This problem was resolved in Cisco IOS Release 12.0(5.3)WC(1):

CSCdt88908

When IGMP packets are received on a port for a non-existent VLAN, the Catalyst 2950 switch no longer loses buffer space on that port.

Initial Configuration

You can assign IP information to your switch in these ways:

Using the Setup program (switch's configuration dialog)

Using DHCP-based auto configuration (refer to the Catalyst 2950 Desktop Switch Software Configuration Guide)

Manually assigning an IP address (refer to the Catalyst 2950 Desktop Switch Software Configuration Guide)

Using the Setup Program

You can use an automatic setup program to assign switch IP information, host and cluster names, and passwords and to create a default configuration for continued operation. Later, you can use CMS or the command-line interface (CLI) to customize your configuration. To run the setup program, access the switch from the PC terminal that you connected to the console port. For information about connecting a PC or terminal to the switch console port, refer to the switch hardware installation guide.

The first time that you access the switch, it runs a setup program that prompts you for IP and other configuration information necessary for the switch to communicate with local routers and the Internet. This information is also required if you plan to use CMS to configure and manage the switch.


Note If the switch will be a cluster member managed through the IP address of the command switch, it is not necessary to assign IP information or a password. If you are configuring the switch as a standalone switch or as a command switch, you must assign IP information.


You will need the following information from your system administrator:

Switch IP address

___________.___________.___________._________

Subnet mask (netmask)

___________.___________.___________._________

Default gateway (router)

___________.___________.___________._________

Enable secret password

___________________________________________


Use this procedure to create an initial configuration for the switch:


Note Be sure the rollover cable is connecting a PC serial port to the switch console port. The data characteristics are 9600 baud, 8 data bits, 1 stop bit, and no parity. Use the supplied rollover cable and DB-9 adapter to connect a PC to the switch console port. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, refer to the Catalyst 2950 Desktop Switch Hardware Installation Guide.

"Using the CLI to Upgrade Member Switches" section


Note Before upgrading your switch to Cisco IOS Release 12.0(5)WC2, read the "Guidelines for Upgrading Switch Software" section for important information.



Note For CMS instructions for upgrading switch software to this release, refer to the online help.


Guidelines for Upgrading Switch Software

When using Cluster Manager to upgrade multiple switches from the Cisco TFTP server, the Cisco TFTP server application can handle multiple requests and sessions. When using Cluster Manager to upgrade multiple switches from the Cisco TFTP server, you must first disable the TFTP Show File Transfer Progress and the Enable Logging options to avoid TFTP server failures. If you are performing multiple-switch upgrades with a different TFTP server, it must be capable of managing multiple requests and sessions at the same time.

Overview of the Switch Upgrade Process

The software upgrade procedure consists of these major steps:

Deciding which software files to download from Cisco.com, as described in the "Which Software Files to Download from Cisco.com" section.

Downloading the combined .tar file from Cisco.com, as described in the "Downloading the New Software and TFTP Server Application to Your Management Station" section. This file contains the IOS image and the HTML files. From Cisco.com, you can also download a TFTP server application to copy the switch software from your PC to the switch, if necessary.

The tar command extracts the IOS image and the HTML files from the combined .tar file during the TFTP copy to the switch.

Copying the current startup configuration file, as described in the "Copying the Current Startup Configuration from the Switch to a PC or Server" section. If the upgrade to the new software fails or if the new startup configuration fails, you can reinstall the previous version of the switch software and use the copy of the startup configuration file to start the switch. If a failure occurs while copying a new image to the switch, and the old image has already been deleted, you will need to use the XMODEM protocol to recover an image for the switch. For more information, refer to the "Recovering from Corrupted Software" section in the "Troubleshooting" chapter of the Catalyst 2950 Desktop Switch Software Configuration Guide.

Using CMS or the CLI to upgrade the software on your switch or switch cluster:

If you are using Cluster Manager to upgrade a switch, follow the steps in the "Using Cluster Manager to Upgrade One or More Switches" section.

If you are using the CLI to upgrade a switch, follow the steps in the "Using the CLI to Upgrade a Catalyst 2950 Switch" section, or "Using the CLI to Upgrade Member Switches" section.

When you upgrade a switch, the switch continues to operate while the new software is copied to Flash memory. If Flash memory has enough space, the new image is copied to the selected switch but does not replace the running image until you reboot the switch. If a failure occurs during the copy process, you can still reboot your switch by using the old image. If Flash memory does not have enough space for two images, the new image is copied over the existing one. Features provided by the new software are not available until you reload the switch.

Which Software Files to Download from Cisco.com

New software releases are posted on Cisco.com and are also available through authorized resellers.

Table 5 describes the file extensions and what they mean for the upgrade procedure. It is easier to upgrade the switch software by using a combined .tar file that contains the HTML files and the IOS image. The upgrade procedures in these release notes describe how to perform the upgrade by using a combined .tar file, and you must use a combined .tar file to upgrade a switch through the CMS.

Table 6 lists the software files for this IOS release.


Note We recommend that you download the combined .tar file that contains the IOS image file and the HTML files. The procedures in these release notes are for upgrading a switch by using the combined .tar file, and the VSM and Cluster Manager are designed to upgrade a switch by using this combined file.


Table 5 Possible Extensions for IOS Software Files

Extension
Description

.tar

A compacted file from which you can extract files by using the tar command. There are two types of .tar files:

A combined .tar file that contains both the IOS image file and the HTML files.

An HTML .tar file that has the letters HTML in its name and contains just the HTML files for the IOS release. From the CLI, you can upgrade the switch software by using this HTML file and the IOS image file.

.bin

The IOS image file that you can copy to the switch through TFTP.

Downloading the New Software and TFTP Server Application to Your Management Station

Follow these steps to download the new software and, if necessary, the TFTP server application, from Cisco.com to your management station:


Step 1 Use Table 5 and Table 6 to identify the files that you want to download.

Step 2 Download the files from one of these locations:

If you have a SmartNet support contract, go to this URL, and download the appropriate files:

http://www.cisco.com/cgi-bin/tablebuild.pl/cat2950

If you do not have a SmartNet contract, go to this URL, and download the appropriate files:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2950

Step 3 Use the CLI or web-based interface to perform a TFTP transfer of the file or files to the switch after you have downloaded them to your PC or workstation.

The readme.txt file describes how to download the TFTP server application. New features provided by the software are not available until you reload the software.


Copying the Current Startup Configuration from the Switch to a PC or Server

When you make changes to a switch configuration, your changes become part of the running configuration. When you enter the command to save those changes to the startup configuration, the switch copies the configuration to the config.text file in Flash memory. To ensure that you can recreate the configuration if a switch fails, you might want to copy the config.text file from the switch to a PC or server.

The following procedure requires a configured TFTP server such as the Cisco TFTP server available on Cisco.com.

Beginning in privileged EXEC mode, follow these steps to copy a switch configuration file to the PC or server that has the TFTP server application:


Step 1 Copy the file in Flash memory to the root directory of the TFTP server:

switch# copy flash:config.text tftp

Step 2 Enter the IP address of the device where the TFTP server resides:

Address or name of remote host []? ip_address

Step 3 Enter the name of the destination file (for example, config.text):

Destination filename [config.text]? yes/no

Step 4 Verify the copy by displaying the contents of the root directory on the PC or server.


Using Cluster Manager to Upgrade One or More Switches

You can use the Software Upgrade feature of the Cluster Manager to upgrade all or some of the switches in a cluster at once. Consider the following conditions when doing an upgrade:

You cannot upgrade Catalyst 2950, Catalyst 2900 XL, and Catalyst 3500 XL switches at the same time. However, you can group together and upgrade Catalyst 1900 and Catalyst 2820 switches at the same time.

Upgrade Catalyst 1900 and Catalyst 2820 switches last. To function efficiently, these switches need to be rebooted shortly after the upgrade occurs. If you do not click Reboot Cluster in 30 seconds after the upgrade, the Catalyst 1900 and Catalyst 2820 switches automatically reboot.

For Catalyst 2950, Catalyst 2900 XL, and Catalyst 3500 XL switches, enter the image_name.tar filename in the New File Name field. The .tar file contains both the IOS image and the web-management code.

For Catalyst 1900 and Catalyst 2820 switches, enter the image_name.bin filename in the New File Name field. The .bin file contains the software image and the web-management code.

Follow these steps to use Cluster Manager to upgrade software. Refer to the online help for more details.


Step 1 In Cluster Manager, select System > Software Upgrade to display the Software Upgrade window.

Step 2 Enter the .tar filename (for Catalyst 2950, Catalyst 2900 XL and Catalyst 3500 XL switches) or the .bin filename (for Catalyst 1900 and Catalyst 2820 switches) that contains the switch software image and the web-management code.

You can enter just the filename or a pathname into the New Image File Name field. You do not need to enter a pathname if the image file is in the directory that you have defined as the TFTP root directory.



Note You can also use Visual Switch Manager (VSM) to upgrade a single switch by following the same software upgrade procedure.



Note Close your browser after the upgrade process is complete.


On Catalyst 2950, Catalyst 2900 XL, and Catalyst 3500 XL switches, new images are copied to Flash memory and do not affect operation. The switch checks Flash memory to ensure that there is sufficient space before the upgrade takes place. If there is enough space, the new image is copied to the switch without replacing the old image, and after the new image is completely downloaded, the old one is erased. In this case, you can still reboot your switch by using the old image if a failure occurs during the copy process.

If there is not enough space in Flash memory for the new and old images, the old image is deleted, and the new image is downloaded.


Note If a failure occurs while copying a new image to the switch, and the old image has already been deleted, you need to use the XMODEM protocol to recover an image for the switch. For more information, refer to the "Recovering from Corrupted Software" section in the "Troubleshooting" chapter of the Catalyst 2950 Desktop Switch Software Configuration Guide.


Using the CLI to Upgrade a Catalyst 2950 Switch

This procedure is for upgrading Catalyst 2950 switches by copying the combined .tar file to the switch. You copy the files to the switch from a TFTP server and extract the files by entering the tar command, with the following results:

Changes the name of the current image file to the name of the new file that you are copying and replaces the old image file with the new one.

Disables access to the HTML pages and deletes the existing HTML files before the software upgrade to avoid a conflict if users access the web pages during the software upgrade.

Reenables access to the HTML pages after the upgrade is complete.

Follow these steps to upgrade the switch software by using a TFTP transfer:


Step 1 If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you have access.

Step 2 Access the CLI by starting a Telnet session or by connecting to the switch console port through the RS-232 connector.

To start a Telnet session on your PC or workstation, enter the following command:

server% telnet switch_ip_address

Enter the Telnet password if you are prompted to do so.

Step 3 Enter privileged EXEC mode:

switch> enable 
switch#

Enter the password if you are prompted to do so.

Step 4 Display the name of the running (default) image file (BOOT path-list). The following example shows the name in italic:

switch# show boot 
BOOT path-list:    flash:current_image 
Config file:       flash:config.text 
Enable Break:      1 
Manual Boot:       no 
HELPER path-list:  
NVRAM/Config file 
buffer size: 32768

Step 5 If there is no software image defined in the BOOT path-list, enter dir flash: to display the contents of Flash memory.

Step 6 Using the exact, case-sensitive name of the combined .tar file that you downloaded, rename the running image file to that name, and replace the .tar extension with .bin. The image filename is then the same as the downloaded filename but with a .bin extension. This step does not affect the operation of the switch.

switch# rename flash:current_image flash:new_image 
Source filename [current_image]?  
Destination filename [new_image]? 

For example:

switch# rename flash:c2950-c3h2-mz.120-5.4.WC.1.bin flash:c2950-c3h2s-mz.120-5.WC2.bin 

Step 7 Display the contents of Flash memory to verify the renaming of the file:

switch# dir flash: 
Directory of flash:/

Directory of flash:/
  3  drwx       10176   Mar 01 2001 00:04:34  html
  6  -rwx        2343   Mar 01 2001 03:18:16  config.text
171  -rwx     1667997   Mar 01 2001 00:02:39  c2950-c3h2s-mz.120-5.WC2.bin
  7  -rwx        3060   Mar 01 2001 00:14:20  vlan.dat
172  -rwx         100   Mar 01 2001 00:02:54  env_vars

7741440 bytes total (4788224 bytes free)

Step 8 Enter global configuration mode:

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z. 

Step 9 Disable access to the switch HTML pages:

switch(config)# no IP http server

Step 10 Enter the boot command with the name of the new image filename:

switch(config)# boot system flash:new_image

For example:

switch(config)# boot system flash:c2950-c3h2s-mz.120-5.WC2.bin

Note If the show boot command entered in Step 4 displays no image name, you do not need to enter this command; the switch automatically finds the correct file to use when it resets.


Step 11 Return to privileged EXEC mode:

switch(config)# end

Step 12 Remove the HTML files:

switch# delete flash:html/* 

Press Enter to confirm the deletion of each file. Do not press any other keys during this process.


Caution In the following step, the tar command copies the combined .tar file that contains both the image and the HTML files. You do not need to copy an HTML .tar file in this procedure.

Step 13 Enter the following command to copy the new image and HTML files to Flash memory:

switch# tar /x tftp://server_ip_address//path/filename.tar flash: 
Loading /path/filename.tar from server_ip_address (via VLAN1):!) 
extracting info (110 bytes)
extracting c2950-c3h2s-mz.120-5.WC2.bin (7741440 bytes)!!!!!!!!!!!!!!!!!!!!
html/ (directory)
extracting html/Detective.html.gz (1139 bytes)!
extracting html/ieGraph.html.gz (553 bytes)
extracting html/DrawGraph.html.gz (787 bytes)
extracting html/GraphFrame.html.gz (802 bytes)!
... 

Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command.

Step 14 Enter global configuration mode:

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z. 

Step 15 Re-enable access to the switch HTTP pages:

switch(config)# IP http server

Step 16 Return to privileged EXEC mode:

switch(config)# end

Step 17 Reload the new software with the following command:

switch# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm] 

Step 18 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.

After the switch reboots, use Telnet to return to the switch, and enter the privileged EXEC mode show version command to verify the upgrade procedure. If you have a previously opened browser session to the upgraded switch, close the browser, and start it again to ensure that you are using the latest HTML files.


Using the CLI to Upgrade Member Switches

Because a member switch might not be assigned an IP address, command-line software upgrades through TFTP are managed through the command switch.

This section provides these procedures:

"Upgrading Catalyst 2950, Catalyst 2900 XL or Catalyst 3500 XL Member Switches" section

"Upgrading Catalyst 1900 or Catalyst 2820 Member Switches" section

Upgrading Catalyst 2950, Catalyst 2900 XL or Catalyst 3500 XL Member Switches

Follow these steps to upgrade the software on a member switch:


Step 1 In privileged EXEC mode on the command switch, display information about the cluster members:

switch# show cluster members

From the display, select the number of the member switch that you want to upgrade. The member number is in the SN column of the display. You need this member number for Step 2.

Step 2 Log in to the member switch (for example, member number 1):

switch# rcommand 1

Step 3 Start the TFTP copy function as if you were initiating it from the command switch.

switch-1# tar /x tftp://server_ip_address//path/filename.tar flash:
Source IP address or hostname [server_ip_address]?  
Source filename [path/filename]?  
Destination filename [flash:new_image]?  
Loading /path/filename.bin from server_ip_address (via!) 
[OK - 843975 bytes]

Step 4 Reload the new software with the following command:

switch-1# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm]

Press Enter to start the download.


You lose contact with the switch while it reloads the software. For more information on the rcommand, refer to the Catalyst 2950 Desktop Switch Command Reference.

Upgrading Catalyst 1900 or Catalyst 2820 Member Switches

Follow these steps to upgrade the software on a Catalyst 1900 or Catalyst 2820 member switch:


Step 1 In privileged EXEC mode on the command switch, display information about the cluster members:

switch# show cluster members

From the display, select the number of the member switch that you want to upgrade. The member number is in the SN column of the display. You need this member number for Step 2.

Step 2 Log in to the member switch (for example, member number 1):

switch# rcommand 1

Step 3 For switches running standard edition software, enter the password (if prompted), access the Firmware Configuration menu from the menu console, and perform the upgrade. Follow the instructions in the installation and configuration guide that shipped with your switch. When the download is complete, the switch resets and begins using the new software.

The Telnet session accesses the menu console (the menu-driven interface) if the command switch password is privilege level 15. If the command switch password is privilege level 1, you are prompted for the password.

You lose contact with the switch while it reloads the software.

Step 4 For switches running Enterprise Edition Software, start the TFTP copy as if you were initiating it from the member switch:

switch-1# copy tftp://host/src_file opcode

For example, copy tftp://spaniel/op.bin opcode downloads new system operational code op.bin from the host spaniel.

You should see the TFTP successfully downloaded operational code message. When the download is complete, the switch resets and begins using the new software. If this message does not appear, refer to the installation and configuration guide that shipped with your switch for more information.

You can also upgrade the switch software through the Firmware Configuration menu from the menu console. For more information, refer to the installation and configuration guide that shipped with your switch.

You lose contact with the switch while it reloads the software.
