Cluster Compatibility

This section describes how to choose command and standby command devices when a cluster consists of a mixture of Catalyst switches. When creating a device cluster or adding a devices to a cluster, follow these guidelines:

When you create a device cluster, we recommend configuring the highest-end device in your cluster as the command device.

If you are managing the cluster through Network Assistant, the device that has the latest software release should be the command device.

The standby command device must be the same type as the command device. For example, if the command device is a Catalyst 3750 switch, all standby command devices must be Catalyst 3750 switches.


Note Catalyst 4500 series switches cannot be configured as standby command devices.

Limitations and Restrictions

You should review this section before you begin working with the device. 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 device hardware or software.

These sections describe the limitations and restrictions:

"Cluster Limitations and Restrictions" section

"Network Assistant Limitations and Restrictions" section

Cluster Limitations and Restrictions

These limitations apply only to the Catalyst 4500 series switches:

By default, clustering is disabled on the Catalyst 4500 series switches.

You must assign an IP address to the Catalyst 4500 series switch if it is a cluster command switch candidate. If the switch is a cluster member candidate, you might not need to assign an IP address.

By default, the HTTP server is disabled on the Catalyst 4500 series switch. To connect the switch to Network Assistant, you must enable the HTTP server on all cluster members.

The HTTP port number on Network Assistant and the Catalyst 4500 series switch must match.

A Catalyst 4500 switch can be a cluster member only if another Catalyst 4500 switch is the command device.

By default, the Catalyst 4500 series switch is configured with five vty lines. If the switch (such as a cluster command device with multiple cluster members) is connected to Network Assistant, you must configure at least eight + x vty lines, where x is the number of vty lines used by other applications. A maximum of 16 vty lines can be configured.

Create a switch virtual interface (SVI) to use for intracluster communication. The SVI must be in the no shut state.

This limitation applies only to the Catalyst 4500 series and Catalyst 3750, 3560, 3550, and 2970 switches:

If a Catalyst 2900 XL or 3500 XL cluster command device is connected to a Catalyst 3550 or a 3750 switch, the command device does not find any cluster candidates beyond the 3550 or the 3750 switch candidates. You must add the 3550 or the 3750 switch to the cluster to see other cluster candidates. (CSCdt09918)

These limitations apply only to the Catalyst 3750, 3560, 3550, and 2970 switches:

If both the active command device and the standby command device fail at the same time, the cluster is not automatically recreated. Even if there is a third passive command device, it might not recreate all cluster members because it might not have all the latest cluster configuration information. You must manually recreate the cluster if both the active and standby command devices simultaneously fail. (CSCdt43501)

When the active device fails in a device cluster that uses Hot Standby Routing Protocol (HSRP) redundancy, the new active device might not contain a full cluster member list.

The workaround is to ensure that the ports on the standby cluster members are not in the Spanning Tree Protocol (STP) blocking state. See the "Configuring STP" chapter in the software configuration guide for more information about verifying port status. (CSCec31495)

These limitations apply only to the Catalyst 2955, 2950, and 2940 switches:

When a cluster of devices have Network Time Protocol (NTP) configured, the command device is not synchronized with the rest of the devices. (CSCdz88305)

When the active device fails in a device cluster that uses HSRP redundancy, the new active device might not contain a full cluster member list.

The workaround is to ensure that the ports on the standby cluster members are not in the STP blocking state. See the "Configuring STP" chapter in the software configuration guide for information about verifying port status. (CSCec31495)

Network Assistant Limitations and Restrictions

The Network Assistant limitations and restrictions are described in these sections.

All Devices

These limitations apply to all the devices described in the "Devices Supported" section:

A red border appears around the text-entering area of some Network Assistant windows. The color of the border changes to green when text is entered. The colored border does not prevent you from entering text. (CSCdv82352)

You cannot switch modes (for example, from guide mode to expert mode) for an open Network Assistant window. The workaround is to close the open window, select the mode that you want, and then reopen the Network Assistant window. For the mode change to take effect on any other Network Assistant window that is open, you need to close that window and then reopen it after you select the new mode. (CSCdw87550)

If you open a window in which you can enter text, open another window, and return to the first window, right-clicking in the text field might make the cursor in this field disappear. You can still enter text in the field. (CSCdy44189)

Catalyst 4500 Series Switches

Network Assistant supports only these features on the Catalyst 4500 series switch:

Administration menu—IP Address, SNMP, System Time, HTTP Port, Users and Passwords, Console Baud Rate, MAC Addresses, ARP, Save Configuration, Restore Configuration, and System Reload

Cluster menu—Create Cluster, Delete Cluster, Add to Cluster, Remove From Cluster, and Hop Count

Device menu—Host Name

VLAN menu—VLAN

View menu—Front Panel, Topology Options, Automatic Topology Layout, and Save Topology Layout

Catalyst 3750, 3560, 3550, 2970, 2955, 2950, and 2940 Switches

These limitations apply only to the Catalyst 3750, 3560, 3550, 2970, 2955, 2950, and 2940 switches:

Network Assistant fails when a device is running the cryptographic software image and the vty lines have been configured by using the transport input ssh and line vty 0 15 global configuration commands to use only SSH. The workaround is to allow SSH and Telnet access through the vty lines by using the transport input ssh telnet and line vty 0 15 global configuration commands. (CSCdz01037)

When you add a new member with a username and password that is different from the existing cluster member usernames and passwords, Network Assistant produces an exception error because of an authentication failure. The workaround is to add the new member without a username and password. When the new member is added to the cluster, remove the existing username and password from the Username and Password fields, enter a new username and password, and then apply it to all cluster members. (CSCdz07957)

When the Link Graphs application has run for hours displaying packet drop and error information, sometimes the X-axis crosses the Y-axis at a negative Y value instead of at Y= 0. This condition occurs with all supported operating systems, browsers, and Java plug-ins. There is no workaround. (CSCdz32584)

After you click Apply or Refresh in the Simple Network Management Protocol (SNMP) window, the window size changes. (CSCdz75666, CSCdz84255)

When you enable log scaling for Link Graphs, the Y-axis scale becomes illegible. There is no workaround. (CSCdz81086)

Changing the password or current authentication while Network Assistant is running causes HTTP requests to fail. The workaround is to close all Network Assistant sessions and then to relaunch it. (CSCeb33995)

When TACACS authentication is enabled only on a command device, member devices cannot be configured. The workaround is to enable TACACS authentication on the member devices. (CSCed27723)

When there are Catalyst 2950 and 2955 devices in a cluster, and you launch the QoS Queue window to configure the devices, and then try to view the settings for other devices by using the device selection menu, Network Assistant halts after 20 to 30 selections.

The workaround is to close and then to restart Network Assistant. (CSCed39693)

If an access control list (ACL) is deleted from a device, all QoS classes on Catalyst 2970 and 3750 switches that use this ACL for traffic classification become unusable. The modification of these classes to use any other traffic classification (match statement) fails. The workaround is to delete the QoS class that uses the undefined ACL and then to recreate it with the intended traffic classification (match statement). (CSCed40866)

When an Open Shortest Path First (OSPF) summary address is added for a 10.x.x.x network, a Windows exception error sometimes occurs.

The workaround is to add the address by using the router ospf <process-id>, area <area-id>, and range <address> <mask> configuration commands. (CSCed87031)

When you select a remote device from the VLAN menu, the displayed table might not show all the connected links between the devices selected in the Host Name and the Remote Device lists. This can also occur when you add a new device to a cluster and open VLAN menu.

To work around the problem, follow these steps:

1. Click Refresh on the Network Assistant toolbar two or three times, or select View > Refresh two or three times.

2. Click Refresh in the VLAN window.

(CSCee06244)

A Java exception error occurs when Network Assistant is in read-only mode and you launch the Port Settings window. This only occurs on Catalyst 3500 XL, 2950 LRE, and 2900 XL switches.

The workaround is to open the Port Settings window with Network Assistant in read-write mode. (CSCee25870)

Host names and Domain Name System (DNS) server names with commas for a cluster command device, member device, or candidate device can cause Network Assistant to behave unexpectedly. You can avoid this instability in the interface by not using commas in host names or DNS names. Do not enter commas when also entering multiple DNS names in the IP Configuration tab of the IP Management window in Network Assistant.

Access control entries (ACEs) that contain the host keyword precede all other ACEs in standard ACLs. You can reposition the ACEs in a standard ACL with one restriction: No ACE with the any keyword or a wildcard mask can precede an ACE with the host keyword.

Important Notes

These sections describe the important notes related to Network Assistant and clustering:

"Cluster Notes" section

"Network Assistant Notes" section

Cluster Notes

This note applies to cluster configuration only on the Catalyst 3550 switches:

The cluster setup privileged EXEC command and the standby mac-address interface configuration command have been removed from the command-line interface (CLI) and the documentation because they did not function correctly.

Network Assistant Notes

These notes apply to Network Assistant configuration on all the devices described in the "Devices Supported" section:

If you use Network Assistant on Windows 2000, it might not apply configuration changes if the enable password is changed from the CLI during your Network Assistant session. You have to restart Network Assistant and enter the new password when prompted. Platforms other than Windows 2000 prompt you for the new enable password when it is changed.

Network Assistant does not display QoS classes that are created through the CLI if these classes have multiple match statements. When using Network Assistant, you cannot create classes that match more than one match statement. Network Assistant does not display policies that have such classes.

Within an ACL, you can change the sequence of ACEs that have the host keyword. However, because such ACEs are independent of each other, the change has no effect on the way the ACL filters traffic.

In the Front Panel view or Topology view, Network Assistant does not display error messages in read-only mode for these devices:

Catalyst 3550 member switches running Cisco IOS Release 12.1(6)EA1 or earlier

Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier

Catalyst 2900 XL or 3500 XL member switches running Cisco IOS Release 12.0(5)WC2 or earlier

In the Front Panel view, if the device is running one of the software releases listed previously, the device LEDs do not appear. In Topology view, if the member is an LRE switch, the CPE devices that are connected to the switch do not appear. The Bandwidth and Link graphs also do not appear in these views.

Open Caveats

These sections describe the open caveats with possible unexpected activity in this software release:

"Open Network Assistant Caveats" section

"Open Cluster Caveats" section

Open Network Assistant Caveats

These Network Assistant caveats apply to the all the devices described in the "Devices Supported" section:

CSCee06244

When you select a remote device from the VLAN menu, the displayed table might not show all the connected links between the devices selected in the Host Name and the Remote Device lists. This can also occur when you add a new device to a cluster and open the VLAN menu.

This is the workaround. Follow these steps:

1. Click Refresh on the Network Assistant toolbar two or three times, or select View > Refresh two or three times.

2. Click Refresh in VLAN window.

CSCee91784

If Network Assistant loses IP connectivity to the switch and an action is performed in the IP Address window, a Java exception error occurs.

The workaround is to close and to reopen the IP Address window when connectivity is restored.

CSCee93695

After the switch loses connectivity, the connect icon in the status bar incorrectly displays a connect status instead of a disconnect status.

There is no workaround.

CSCee96650

If you select multiple ports and launch the Port Settings window from the popup menu of the Front Panel view, it might take approximately 7 seconds to launch.

The workaround is to launch the Port Settings window from the feature bar.

CSCef02719

The Network Assistant window flickers if you click Cancel in the Application > Print window.

There is no workaround.

CSCef20111

If you try to add or delete a cluster from the CLI and from Network Assistant simultaneously, you might get Java exception errors.

The workaround is to not to add or delete clusters simultaneously from the CLI and Network Assistant.

CSCef24188

A Java exception error occurs if Cisco Discovery Protocol (CDP) is disabled on a cluster member.

There is no workaround.

CSCef44654

If you click Install Packages in the Application Updates window and enter a wrong username or password in the network authentication window, or if you click Cancel, an error window appears, and you cannot install any packages.

The workaround is to restart Network Assistant.

CSCef47554

A Java exception error occurs in the IGMP Report window when Network Assistant is in read-only mode and is connected through a secure HTTP (HTTPS) connection to a command switch running a Cisco IOS cryptographic image.

There is no workaround.

CSCef49951

If you launch the Application Updates window and enter the wrong username or password in the network authentication window, or if you click Cancel, an error window appears, and no packages appear in the Application Updates window.

The workaround is to click Refresh in the Application Updates window three times or to restart Network Assistant.

CSCef67553

In Network Assistant, some windows such as VLAN, Host Name, and so on might not launch from the Front Panel view popup menu for Catalyst 4500 series switches.

The workaround is to close Network Assistant and relaunch it.

CSCeg38631

After you upgrade Network Assistant packages to 1.0(2), the About window still shows the version as 1.0(1a).

You can verify the upgrade by opening the About window and clicking Package Info, which opens the Installed Packages window. You see a table that lists the installed packages. The first column lists the device package names and their versions. The versions should be 1.0(2). Ignore the information in the Version column.

CSCeg60113

On Catalyst 3750 switches, when you add a trap manager with all the traps enabled, the trap manager is not applied to the switch.

There is no workaround in Network Assistant. Use the command-line interface to configure trap managers with all the traps enabled.

CSCeg75813

The Application Updates window and the Installed Packages window show two version numbers for each package.

The Name column in the Application Updates window shows the names of packages and the correct version numbers. Ignore the values in the Version column and Installed Version column.

The Name column in the Installed Packages window shows the names of packages and the correct version numbers. Ignore the values in the Version column.

CSCeg78814

A feature might show an unusual error after a Network Assistant package is installed.

All the available package updates were not installed. Choose Application > Application Updates from the feature bar, select Latest from the Show list, and install all the packages.

CSCeh12708

If you upgrade a Catalyst switch to Cisco IOS 12.1(22)EA3 or later or to Cisco IOS 12.2(25)SEA or later, Network Assistant no longer recognizes the switch.

Network Assistant connects to Cisco.com to get an application update when this happens. When it displays an authentication window, enter your Cisco.com username and password. When the Application Updates window appears, choose Latest in the drop-down list, select all the packages that are shown in the window, and click Install.

After the application update is installed, you are forced to close Network Assistant. When you restart it, it can recognize and manage the upgraded Catalyst switch.

Open Cluster Caveats

This cluster caveat applies to the all the devices described in the "Devices Supported" section:

CSCef48257

After the cluster command device is reloaded, it might not be able to re-establish communication with the cluster members connected through its routed ports.

This is the workaround. Follow these steps:

1. Use the no cluster run global configuration command on the cluster command device and the cluster members that have lost connectivity to the command device.

2. Use the cluster member global configuration command to add the cluster members back to the cluster.

CSCeg60365

If a Catalyst 2970 switch is a cluster command device and a Catalyst 3750 or 3550 switch is a cluster member, enabling IGRP on a network on the Catalyst 3750 or 3550 switch creates a Premature EOF error.

There is no workaround. Make the Catalyst 3750 or 3550 switch the command device.

Resolved Caveats

This section describes the resolved caveats.

Caveats Resolved in Network Assistant 1.0(2)

These caveats were resolved in this release:

CSCee06206

When a Catalyst 3750 stack member leaves or joins the device stack, the entire stack no longer disappears from the Topology view.

CSCee26671

When you click Refresh in the Stack Settings window, the latest information about the device cluster now appears.

CSCee82854

An error no longer occurs when you modify the port settings of multiple ports by using the Modify Port Settings window launched from the popup menu of the Front Panel view.

CSCef31685

In the Topology view, the EtherChannel links between two Catalyst 4500 series switches now correctly appear in red (blocked) instead of green (forwarding).

Caveats Resolved in Network Assistant 1.0(1a)

This caveat was resolved in this release:

CSCef89938

When Network Assistant 1.0(1) is launched, and when the locale settings in the Control Panel > Regional Options window in Microsoft Windows are not set to English (United States), the error message None of the version files parsed correctly no longer appears, and the application works correctly.

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
