New Features

When you install and launch Cisco Network Assistant 2.1, you can

Manage Cisco EtherSwitch service modules, used on Cisco 2800 and Cisco 3800 integrated services routers, as if they were Cisco Catalyst 3560 and Catalyst 3750 switches.

Create and manage a new device group known as a community. Unlike a cluster, a community can contain Cisco access routers, Cisco Aironet Access Points, and Cisco PIX Firewalls. You can manage the devices in a community with greater security and availability than the devices in a cluster.

This set of basic networking features is supported for Cisco access routers and Cisco Aironet Access Points:

Software Upgrade
Users and Passwords
Back Up/Restore Configuration
Save Configuration
System Messages (requesting notification and getting reports)
System Time

Upgrade the software on community devices by dragging and dropping a Cisco IOS image onto a device icon in the Topology view. You do not need a TFTP server to support this feature.

Use the Smartports Advisor to quickly configure ports that are connected to desktops, IP phones, switches, routers, and access points.

Use a new wizard to convert a cluster into a community. It leaves the cluster definition intact so that you can still manage the devices as a cluster if you choose to.

System Requirements

Cisco EtherSwitch service modules:







Note The Topology view of Network Assistant supports Catalyst 6500 switches. You cannot add these devices to a community or cluster, but you can launch device manager for them from the Topology view.

Access Points

Cisco Aironet 1100 and 1200 series

Network Assistant supports them only if they run a Cisco IOS image.

Cisco Aironet 350 series

You can display these devices as neighbors in a Topology view; no other Network Assistant support is available.


Cisco PIX 515E Firewalls

Note PIX Firewalls do not support the Cisco Discovery Protocol, so they are not automatically shown as neighbors in the Topology view. They are shown only after you add them to a community by using a Create Community or Modify Community window. To see a PIX Firewall link to another community member, you must add the link manually by selecting Add Link in a Topology popup menu.

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, Back Up/Restore Configuration, Software Upgrade, System Reload, and System Message Notification

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

Port menu—Smartports Port Setup, Port Settings, and Port Security

Device menu—Hostname and Security Wizard

VLAN menu—VLAN and Voice VLAN

Reports menu—Inventory, Bandwidth Graphs, Link Graphs, and System Messages

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

Community Limitations

These limitations apply only to communities:

A community can contain up to 20 devices. This limit is enforced whenever you add devices to a community.

Furthermore, a community cannot contain more than 16 nonmodular switches, 4 modular switches, 12 access points, and 2 routers. These limits are checked during the launch of Network Assistant; you receive a warning if they are exceeded.

Changes to the topology or network do not propagate across all open Network Assistant sessions connected to the same community. You see this inconsistency when multiple Network Assistant sessions are open on one desktop, and they point to the same community.

Open one Network Assistant session per desktop per community. (CSCeh53619)

The Topology view sometimes displays duplicate devices and links. There is no workaround. (CSCeh61352)

In the Topology view, the horizontal scrollbar sometimes does not scroll far enough left to show the complete topology. The workaround is to right click the Topology view and select Automatic Topology Layout from the popup menu. (CSCeh56952)

In the Topology view, if there are multiple links between community members and one of the links is blocked, it is shown in green, not in gray. There is no workaround. (CSCeh60050)

In the Topology view, the redundant link for an HSRP group is not shown. There is no workaround. (CSCeh54526)

If a community has members that are connected to a member through a hub or Gigastack module, the Topology view shows all the connections. But if nonmembers are connected to a community member through a hub or Gigastack module, the Topology view shows only the connection of the first nonmember.

Accessing a community through a router running NAT (Network Address Translation) is not supported.

Cluster Limitations

These limitations apply only to clusters:

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)

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)

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)

Community and Cluster Limitations

These limitations apply to both communities and clusters:

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

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)

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)

Hostnames 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 hostnames 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.

When you reload a device with Network Assistant, it saves the running configuration. If you want to reload without saving the running configuration, use the CLI. (CSCeh24259)

Important Notes

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

"Community Notes" section

"Cluster Notes" section

"Network Assistant Notes" section

Community Notes

This note applies to community on all the devices described in the "Devices Supported" section:

All the devices for the topology of a community are derived from the CDP (Cisco Device Protocol) table of Cisco IOS. Therefore, the Topology view shows duplicate devices when CDP discovers duplicate devices. This happens for a single device when the command show cdp neighbor is issued. Two devices are displayed: one with the actual hostname (for example, abc), the other with hostname.domainname (for example,

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:


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 Hostname 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.


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.


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

There is no workaround.


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.


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

There is no workaround.


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.


In Network Assistant, some windows such as VLAN, Hostname, 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.


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.


The Show CLI Summary panel in the Network Assistant wizards does not display the CLI commands accurately.

After you click Finish, you see the commands that are actually applied to the device.


In the Link Graphs window, when you choose the Packet Drops & Errors option for a Catalyst 4500 or 4900 switch, you see inaccurate link traffic statistics.

There is no workaround.


If you change the default setting of the Graph Display Type in the Bandwidth Graph window, the change is not retained for your next use of the window.

Check that the Graph Display Type setting is what you want whenever you use the window.


In the columns of the Inventory window, when you click the arrow that shows ascending sorting (an arrow pointing downwards) or the arrow that shows descending sorting (arrow pointing upwards), the results are the opposite of what you expect.

If an arrow icon does not give you the sorting that you want, click it again to reverse the sorting.


The Smartports Port Setup window does not show the LED status of the ports.

You can use the window to configure ports even if status information is not shown.


When you select a VLAN and assign an aging time in the MAC Addresses window, if you check Apply to Other VLANs, the box does not remain checked.

The aging time is nevertheless applied to all the VLANs.


Changing the severity criteria for being notified of some system messages sometimes causes unwanted changes to the criteria for other system messages.

Limit the range of severity to which the changes apply, and fewer unwanted changes occur.


If a dual-media port on a Catalyst 4500 switch, model WS-C4948 or model WS-X4506-GB-T, is configured to RJ-45 and you apply a Smartports port macro, the port is changed to SFP, the default setting. The connection to the port is lost.

Reconfigure the media type to RJ-45 through the Port Settings window.


If you change a hostname while a Network Assistant window is open, the window might not display the new hostname, even if you refresh the window.

To see the new hostname, close the window and then reopen it.


The interface that you select in the Select Interface window is sometimes not displayed in the Interface field of the Link Graphs window.

The workaround is to enter the correct interface in the Interface field.


The Software Upgrade feature cannot use a third-party TFTP server running on the same PC where Network Assistant was launched.

Network Assistant has an embedded TFTP server, so there is no need to run a different TFTP server on the PC. Use the standard mode of the Software Upgrade feature, and the embedded TFTP server will transfer the software upgrade file.


The Media Type column in the Port Settings window appears even if the modules of a Catalyst 4500 switch do not support AWP (alternate wired ports). If this case, the column fields display as N/A.

There is no workaround. The other columns in the window are not affected.

CSCeh41085, CSCeh50720

If you open the Modify Port Settings window or Modify Port Mode window twice in succession from the Front Panel view (by right clicking on a port, choosing Port Settings or VLAN from the popup menu, and repeating these actions for another port), the windows show the settings for the port you selected first.

Make sure that the Interface field in these windows is for the port that you selected. Always close these windows between port selections.


When you click Port Settings in a Front Panel view popup menu, you configure port settings in the Modify Port Settings window and return to the Front Panel view without seeing a verification of the new settings.

To verify your work, open the Port Settings window from the feature bar and review the settings there.


If you install Network Assistant on Windows 98 in a root directory—for example, C:\ or D:\—the installation is corrupted.

Install in the default directory, C:\Program Files\Cisco Systems, or choose a local installation directory that is not a root directory.


In the Port Settings window, you must apply a change to some speed settings before you can change a duplex setting.

After you configure a speed setting, click Apply; then configure a duplex setting.


If you shut down connectivity to a device while Network Assistant is saving or backing up its configuration, the save or backup operation fails.

Reconnect to the device, and retry the save or backup operation.


If you try to close Network Assistant while a task is running, Network Assistant asks whether you really want to exit but does not say what might happen if you do.

Decide whether an important task is in progress. If it is, answer by clicking no.


You cannot backup a configuration when hard-disk space on your PC is low.

Free at least 10 KB of hard-disk space for each device that you want to back up.


The Security Wizard sometimes does not show a warning message when it applies an ACL to a port that already has an ACL applied to it.

There is no workaround.


You cannot save a configuration when the flash memory in the device is low.

If possible, free flash memory in the device.


In a Topology view for a community, the link icons for routed, trunk, and Gigastack links are not shown.

There is no workaround.


Network Assistant gives a warning because it cannot display the configured HTTP port number for devices that run Cisco IOS 12.1.

Close the warning window, and set the HTTP port number that you want to use.


When you create an enable password through Network Assistant, you create an enable secret (encrypted) password. Therefore, no entry for the password appears on the Enable Password tab of the Users and Passwords window.

If you do not want to create an encrypted password, the workaround is to use the CLI to create a nonencrypted password. Network Assistant will prompt users for this password when they connect, even though the password does not appear on the Enable Password tab.


Access points and routers are not supported in the Front Panel view, but sometimes the check boxes for these devices are checked, even if they are grayed out.

There is no workaround.


Even if you see the message Port security is only supported on static access interfaces, it is also supported on ISL trunk ports and 802.1Q trunk ports if these ports are supported by the Cisco IOS image.

The Port Security window lists all the ports that are eligible for port security. If a port is not listed, configure the port as necessary through the VLAN window, and return to Port Security window to configure the port security settings.


If the window for the Cluster Conversion window is covered by other windows, launching it again does not bring it to the front.

Go to the Window menu and select it.


A community member might become unmanageable if its Cisco IOS image is downgraded from a cryptographic image to a noncryptographic image.

Use the Modify Community window to remove the device from the community, and then add it to the community again.


If you cancel the authentication window for every device in a community, the community is unmanageable. You cannot reconnect to it or connect to another community.

Launch Network Assistant again.


The port colors on the Front Panel view are inaccurate when ports on Catalyst 2950, 3550, and 3750 switches are set to half duplex.

Open the Port Settings window to confirm that the port settings are correct.


Network Assistant cannot change the default HTTP port number from 80 to another value on a switch that runs Cisco IOS 12.2(20)EWA.

The workaround is to change the port number through the CLI with the command ip http port port#. Network Assistant continues to show the port number as 80.


When the media type is changed on a S-X4506-GB-T linecard through the CLI or through another instance of Network Assistant, your instance of Network Assistant may be put into an inconsistent state, resulting in a blank Port Settings window.

The workaround is to shut down your instance of Network Assistant and launch it again. You can then use the Port Settings window without a problem.


You cannot see the PoE columns in the Port Settings window for Catalyst 4503, 4506, or 4507R switches that run Cisco IOS 12.2(20)EWA and have a WS-4548, WS-4524, or WS-4506-GB-T PoE line card.

The workaround is to upgrade the software on the switch to a later version of Cisco IOS.

Open Cluster Caveats

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


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.


If you add a member whose hostname ends in a -n (hyphen and number) and the hostname of an existing member ends in the same -n, the hostname of the new member might change to the hostname of the existing member.

Avoid adding a member to a cluster whose hostname ends in -0 to -16.

Resolved Caveats

This section describes the resolved caveats.

Caveats Resolved in Network Assistant 2.1

These caveats were resolved in this release:


The installation of Network Assistant no longer fails if McAfee VirusScan Enterprise 8.0 is installed.


When TFTP packets are lost in the network, the lost data is now retransmitted correctly; the TFTP file transfer no longer fails.

CSCef44654, CSCef49951

In updating Network Assistant, if you enter a wrong username or password in the authentication window, or if you click Cancel, you are no longer prevented from making the correct entries and continuing the update.


On Catalyst 3750 switches, when you add a trap manager with all the traps enabled, the trap manager is now applied to the switch.


When you select Administration > IP Address, Network Assistant no longer allows you to assign an existing IP address to another VLAN using the same subnet mask.


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 now recognizes the switch.

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.
