These capabilities have been added to URT for release 1.2.1:
![]() | Caution It is important to note that CiscoWorks2000 CWSI Campus does not support Windows 2000. Therefore, the URT administrative interface cannot be installed on Windows 2000. |
These capabilities have been added to URT for release 1.2:
![]() | Caution URT 1.2.1 works only with the CWSI Campus 2.3 or 2.4 application suite that is included with CiscoWorks2000. Do not attempt to use URT 1.2.1 with any other version of CWSI or CWSI Campus. You must install CiscoWorks2000 CWSI Campus before installing URT. |
Read the planning and installation information in the Using the User Registration Tool manual before installing URT. For URT 1.2.1, the installation process no longer asks whether you want to continue to use MAC-based (host-based) VLAN associations. URT 1.2.1 automatically enables MAC-to-VLAN mappings.
This section describes the host-based dynamic VLAN support incorporated in URT 1.2.1. Host-based VLANs use MAC addresses instead of user names to determine the VLAN assignment.
URT's main capability is to assign users to VLANs. This allows you to develop VLAN-based services and ensure that users always get the expected services. As users move from machine to machine in your network, URT can identify the user based on user name and make the appropriate VLAN assignment.
However, URT does not support user-based assignment on all computers. In some cases, such as UNIX, this is because a single machine can support multiple simultaneous users, whereas the associated switch port can be in only one VLAN at a time. In other cases, there is not an appropriate network login that can be captured by the URT client.
Host registration allows you to assign VLANs based on a host's media access control (MAC) address, which is the number associated with the network interface card (NIC) in the computer. Because the VLAN mapping is based on MAC address, it is the host that is mapped to a VLAN, not the user.
However, if you have a one-to-one correspondence between users and hosts (that is, users do not move between hosts), then host registration and user registration will provide essentially identical network policy control. Also, because the VLAN is based on the host's MAC address rather than the switch port, you can move the host to a different port (for example, move a laptop between buildings) and make the desired VLAN assignment.
Host registration is the same capability as switch-based dynamic VLANs using CiscoWorks2000 User Tracking and Catalyst 5000 switch VMPS servers.
You can use host registration with any host that is directly attached to a port on a supported switch. You cannot use host registration with hosts attached to hubs, unsupported switches, or routers.
With host registration, you can include Macintosh, Linux, UNIX, and other types of hosts in your dynamic VLAN planning. You can also use host registration with Windows machines, even if the Windows version supports user registration.
User registration always takes precedence over host registration. URT applies VLAN assignments in this priority order:
1. User name---If you assign a specific VLAN to a user name, that VLAN is used.
2. NT or Active Directory group, or NDS organizational unit membership---If a user name does not have an assigned VLAN, and the user name is a member of an NT or Active Directory group, or NDS organizational unit, URT uses the VLAN assigned to the group or organizational unit (if there is one).
3. MAC address---If a user name does not have a VLAN assignment, and the user name is not a member of a group or organizational unit that has a VLAN assignment, then URT uses the VLAN assigned to the MAC address of the machine (host registration).
4. Logon VLAN---If there are no VLAN assignments for user name, group name, organizational unit, or MAC address, the user remains in the logon VLAN.
In many cases, you do not have a choice between user and host registration. If you want to use dynamic VLANs for hosts that do not support user registration, you must use host registration.
For those clients that support both user and host registration (Windows 95, Windows 98, Windows NT 4.0, and Windows 2000), consider these points when deciding between user and host registration:
Using the User Registration Tool describes the interaction between URT and User Tracking. With URT 1.2.1, there is increased interaction.
Each time you start URT, URT reads the User Tracking tables. Any new MAC address-to-VLAN mappings in User Tracking are added to the URT MAC Address list in the folder pane. However, if a MAC address already has a VLAN assignment in URT, any assignment for that address in User Tracking is ignored. Thus, when you start managing a MAC address in URT, you must continue managing it within URT (unless you explicitly remove it from URT).
If you make new mappings in User Tracking while URT is running, you can import that new mapping into URT by selecting the MAC address folder in URT and then selecting View>Refresh. All new non-conflicting mappings are added to URT.
When URT reads the User Tracking tables, URT also obtains a list of discovered MAC addresses. When you add a MAC-to-VLAN mapping in URT, URT presents you with a list of these discovered but unmapped addresses. To get an up-to-date list of MAC addresses, Cisco recommends that you do a discovery in User Tracking before starting URT when you intend to work with MAC addresses.
These sections describe the tasks for implementing host registration:
The list of MAC addresses in the main URT window displays only MAC addresses for which there are VLAN mappings. Although URT is aware of all MAC addresses discovered in the network by CiscoWorks2000 User Tracking, you can add only those addresses for which you are creating mappings to the main window list.
URT automatically adds any MAC addresses that have been mapped to VLANs in User Tracking to the URT main window.
Before you start URT to create MAC-to-VLAN mappings, start the CiscoWorks2000 User Tracking application and do a host discovery. User Tracking will collect data on all the MAC addresses it can find in your network. URT displays this information so that you can select MAC addresses from a list. By priming the list of MAC addresses, you will not need to manually enter the MAC addresses.
Step 1
Select the MAC Addresses folder in the URT folder pane and click the Add button (or select Edit>Add).
URT opens the Host Association window (Figure 1). URT displays all unmapped MAC addresses found by User Tracking in the Discovered MACs list. If a MAC address is already mapped to a VLAN, it is not displayed in the list (mapped MAC addresses are only displayed in the main URT window).

Step 2 Select the MAC addresses you want to map to a particular VLAN in the list of discovered addresses, and click Add>> to add them to the selected MACs list. You can map more than one address at a time, but all MAC addresses in the selected MACs list are mapped to the same VLAN.
You can scroll through the list of addresses quickly by typing the MAC address into the Enter a MAC address field (this is shown in Figure 1). As you type, URT scrolls through the list of discovered MACs to the next address that matches what you have typed. Eventually, the address you are looking for will be highlighted, unless it is an undiscovered address.
If the desired address is not in the discovered MACs list, enter the entire MAC address in the edit box and click Add>> to add it to the selected list. URT does not require that User Tracking discover the MAC address.
You must use hyphens to separate the bytes in the MAC address; you cannot use colons.
Step 3 When you have selected all of the MAC addresses you want to map to the same VLAN, select the VTP domain and the desired VLAN and click OK.
You can change the VLAN mappings for any host that has a mapping, whether the mapping was made in URT or User Tracking.
Step 1 Double-click the MAC address whose mapping you want to change in the MAC Addresses folder, or:
Select the address and click the Associate VLAN button.
URT opens the Associate VLAN window.
Step 2 In the Associate VLAN window, select the desired VTP domain and VLAN and click OK.
If you no longer want to use host registration with a host, delete its mappings in URT.
Step 1 Select the MAC address you want to delete in the MAC Addresses folder.
Step 2 Select Edit>Delete.
URT deletes the MAC address and its VLAN mappings.
If you want to use switch-based VMPS servers rather than URT servers to manage host registration, you can still use the URT interface to create the host-based VLAN mappings.
When you save the URT database, URT creates a vmps10.dat file in the dat folder in the URT installation folder on the URT server machines. See the Catalyst 5000 documentation for information on implementing switch-based VMPS using this file.
You can now remove ClientService from Win9x clients by using the command UrtClientUninstall.bat from the PDC.
Step 1 In the Urt.bat file on the PDC, comment out the line containing %WINDIR%\\onoffhandler.
Step 2 Execute @start %WINDIR%\\urt\\UrtClientUninstall.bat
URT 1.2.1 includes a command that you can use to add user-to-VLAN or host-to-VLAN mappings from the command line. This is primarily useful if you have an automated method of creating a text file with your required mappings. You can pipe this text file into the urt command, thus creating mappings using a batch process.
The urt.bat file resides in the bin subdirectory of the CWSI root directory.
The syntax of the urt command is:
urt -cli -server ANI-server-name [ < textfile ]You can get help information by entering urt -help.
-cli | Indicates that you are running URT from the command line rather than the GUI. |
-server ANI-server-name | The name of the ANI server used by CiscoWorks2000. |
< textfile | Optionally, the name of a text file that contains the user-to-VLAN and host-to-VLAN mappings. If you do not specify a file, you must enter the mappings at the command prompt after you start the command. Whether you enter the mappings from a file or the command prompt, the mappings must be in this format:
Any mappings you enter override existing mappings in the URT database. The NT domain or NDS tree must already be defined in URT through GUI before you can enter mappings for them using the command line. You cannot add domains or trees through the command line. |
Here are some additional tips to troubleshooting URT. For more tips, see the troubleshooting chapter in Using the User Registration Tool.
(a) Try to start CiscoWorks2000 CWSI Campus. If CWSI Campus cannot start, the ANI connection problem is due to a CiscoWorks2000 problem.
(b) If you can successfully start CWSI Campus, make sure that you installed the URT CWSI Upgrade package.
(c) If you installed the CWSI Campus package, make sure that you are using the same ANI server name in CWSI Campus and in URT.
For CWSI Campus, you can find the ANI server name in the etc\cwsi\ani.properties file. Look for the AniName parameter.
For URT, you can find the ANI server name in the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\urtsvc registry entry. Look for the Args parameter.
If the names are different, rerun the URT installation program and enter the correct CWSI Campus ANI server name when prompted.
The user guide and online help for URT was not updated for 1.2.1. A number of changes made in release 1.2.1 have made certain statements in the 1.2 documentation incorrect. This section describes these changes.
Known problems are unexpected behaviors or defects in the product. They are graded according to severity level. These release notes contain information for severity levels 1 and 2 only.
You can search for known problems on the Cisco bug tracking system tool, called Bug Navigator II. To access Bug Navigator II, do one of the following:
Table 1 describes restrictions or other known issues for using URT.
| Bug ID | Summary | Explanation |
|---|---|---|
CSCdp52403 | Setting VMPS servers on a Catalyst 4000 switch running CatOS 5.2.2 using the URT management interface | You cannot set VMPS servers on a Catalyst 4000 switch running CatOS 5.2.2 using the URT management interface. If you see the message "Cannot set VMPS on the following switch:" Step 1 Verify that the SNMP Community string in CWSI corresponds to the SNMP Community string in the switch. Step 2 If this does not help, telnet to the switch and in the enable mode, enter the command: set vmps server <IP address of URT Server> [primary] Please refer to switch documentation for more information on usage. This problem does not occur on CatOS version 5.1.64 and will be addressed in a future CatOS release. |
CSCdp50922 | Using URT with port channelling set to mode Off | You cannot use URT with port channelling on a switch set to mode Off. URT cannot switch the port to the user assigned or logon VLAN and the port remains in state dyn- . |
None | Using URT with span VLAN | You cannot use span VLAN on a switch with URT. If you are using span VLAN, you must turn off spanning, then disable and enable the dynamic switch port. |
None | Some Win95 PCs may show Windows blue screen on login | This seems to be a problem with specific PCs running Windows 95 and OSR2(OEM Service Release 2). However, if you use OSR2.1 (like Windows 95 4.00.950B), you probably will not see this problem. |
None | Uninstalling and reinstalling CWSI Campus with URT installed | If you are already using URT, and you need to uninstall and then reinstall the CiscoWorks2000 CWSI Campus suite, you must first make a copy of the urt.dat file. This file contains your URT configuration, and CWSI Campus will delete it during uninstallation. The file is in the db\data\ subdirectory of the CWSI Campus root directory. After you reinstall CWSI Campus, copy urt.dat back into the db\data\ subdirectory. |
None | Changing to a secondary URT (VMPS) server | In Chapter 1 of Using the User Registration Tool, section "What Happens to User Logons If URT Servers Are Disabled," page 1-4, the note says that it takes 5 minutes for a switch to recognize that the URT server it uses for VMPS is not available and to change to a secondary URT server. In fact, it takes 8 to 15 minutes for this changeover to occur. |
None | Catalyst 3500XL switch clustering feature | URT does not directly support the switch clustering feature. You must assign each switch an IP address if you want to configure the switch's VMPS addresses through URT. If you use clustering, you must use the switch's commands to configure the VMPS server addresses. |
None | Installing the client service | To install the URT client service on Windows NT workstations, you must log into the CiscoWorks2000-URT machine with administrative privileges in the NT domain that contains the Windows NT machines. It is not sufficient to log into the domain from the URT interface. |
None | Multi-homed Windows 95 and Windows 98 systems | URT does work with Windows 95 or Windows 98 clients that are multi-homed, that is, clients that have more than one active NIC or an active NIC with an active modem. These clients must have only one active network connection. |
