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 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

There are two Java plug-ins that are supported on these platforms:


Note We recommend using Java plug-in JRE 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/cat2950

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

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

Java plug-in JRE 1.3.0

This plug-in is not downloaded automatically. However, you can download it from this URL:

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


Note Uninstall older versions of the Java plug-in before installing the Java plug-in JRE 1.3.0.


Solaris Users

Two Java plug-ins are supported on the Solaris platform:


Note We recommend using JRE 1.2.2_07.


JRE 1.2.2_07

You need to install the Java plug-in and the JRE 1.2.2_07:

Download and install the Java plug-in for Solaris from this URL:

http://www.sun.com/software/solaris/netscape/jpis/

Install the JRE 1.2.2_07 from this URL:

http://www.sun.com/software/solaris/java/download.html

Follow the links in the section titled J2SE: Java 2 Standard Edition (1.2.2_07 Localized) for the JRE 1.2.2_7 plug-in instructions.

JRE 1.3.0

The JRE 1.3.0 does not require you to download a separate Java plug-in as it is included with the JRE 1.3.0. Download and install the JRE 1.3.0 for Solaris from this URL:

http://www.cisco.com/cgi-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(5.2)WC(1) 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

This section should be reviewed 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.

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.

Caveats

This section describes possible unexpected activity by IOS Release 12.0(5.2)WC(1).

CSCdt24089

If the Catalyst 2950 switch contains multicast addresses, the MIB walk of Dot1dTpFdbEntry can be inefficient, sometimes consuming excess CPU cycles on the switch.

There is no workaround.

CSCdt88908

If IGMP packets are received on a port for a non-existent VLAN, the Catalyst 2950 switch loses buffer space on that port. The switch supports only 64 VLANs; therefore, this only occurs if the Catalyst 2950 switch is connected to a switch that has more than 64 VLANs configured.

There is no workaround.

CSCdt24814

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.

CSCdt04001

On the Catalyst 2950 switches, when the privilege level is changed for the interface, commands can be executed with the newly configured privilege level. However, the switch does not save the arguments associated with the command, and after a reload, the configured commands are not executable.

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. (CSCdt48569)

CSCdt57346

When you use the show rmon history command, the value for the collision is cumulative instead of being unique for each sample. The value for a collision in a given sample can be calculated by subtracting from the previous sample.

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.

CSCdt18106

The snmpwalk on the Catalyst 2950 CISCO-IP-STAT-MIB loops continuously when using IP accounting precedence on VLANs other than VLAN1.

The workaround is to use individual snmpget requests to retrieve data.

CSCdt68204

If you continuously ping a switch from a PC and the links from the switch to the network are brought down, one link from the switch to the network is restored, ping does not resume.

The workaround is to run the clear cam command.

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

The DHCP server should contain 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. If the switch gets configured from the dynamic IP pool, a duplicate or different IP address might be assigned.

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 is displayed 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 crashes.

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.

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 also is 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.

snmp community public ro 
cluster enable cls_name 
 
end 

Step 13 Verify that the information is correct.

If the information is correct, enter Y at the prompt, and press Return.

If the information is not correct, enter N at the prompt, press Return, and begin again at Step 1.

Use this configuration? [yes/no]: y 


After you complete the setup program, the switch can run the created default configuration. If you want to change this configuration or want to perform other management tasks, use one of these tools:

CMS from your browser (see the "Installing the Required Plug-In" section, and the "Accessing CMS" section)

Command-line interface (CLI) (refer to the software configuration guide)

The switch software configuration guide provides more information about how to set a password to protect the switch against unauthorized Telnet access and how to access the switch if you forget the password.

Accessing CMS

A browser plug-in is required to access CMS. See the "Installing the Required Plug-In" section. After you have assigned an IP address to the switch and installed the plug-in, you can access the switch from your browser and use the Cluster Management application to configure other switches. To use the web-based tools, see the "Software Requirements" section to set up the appropriate browser options.
