Managing VLAN Ports with VLAN Port Assignment

---

VLAN Port Assignment is an application that displays device, port, and related VLAN information for an associated VTP domain in a tabular format and helps you manage ports on your network's VLANs.

Use VLAN Port Assignment to:

•Assign or move ports to a VLAN.

•View port, device, and trunk attributes.

•View and find port information in a VTP domain.

•Configure VLANs on a trunk.

•Show and highlight a selected device or VLAN on a selected VTP domain.

The following topics provide you with information about:

VLAN Port Assignment Concepts

To enable end-user ports to participate in a specific VLAN, you must first assign the ports. You assign ports to specified VLANs. The VLANs allow the ports to share the same broadcasts. Ports that are not assigned to the VLAN cannot share these broadcasts. For more information about VLANs, refer to the "Virtual LANs (VLANs)" section. For VLAN Port Assignment to work correctly, the ANI Server must discover the network. The ANI Server requires a properly configured network to complete network discovery. See Installing and Setting Up Campus Manager or the ANI Server online help for information about setting up your network.

Starting and Navigating in VLAN Port Assignment

From the CiscoWorks desktop, select Campus Manager > VLAN Port Assignment. The main VLAN Port Assignment Main Window appears (see Figure 4-1). See Table 4-1 for a description of the elements in the VLAN Port Assignment window.

Another way to start VLAN Port Assignment is through Topology Services. In Topology Services, click a VTP domain and select Tools > VLAN Port Assignment.... VLAN Port Assignment opens, displaying the domain you selected.

Figure 4-1 VLAN Port Assignment Main Window

Table 4-1 VLAN Port Assignment Window Elements

Item	Description
Menu Bar	Contains VLAN Port Assignment Commands
Tool Bar	Provides quick access to frequently used menu options
VTP Domain Chooser	Allows you to select a VTP Domain. If you started VLAN Port Assignment from Topology Services, this is automatically filled in.
Port Query Panel	Allows you to find specific ports based on your search criteria. For more information on search criteria fields, see the VLAN Port Assignment online help.
Ports Summary Table	Contains fields providing details about VLAN ports. It also displays native and auxiliary VLANs. A native VLAN carries data traffic. An auxiliary VLAN carries voice and data traffic.
Port Move Panel	Allows you to move the selected port in the summary table to a VLAN.
Status Bar	Shows the current ANI Server status. Click the color-coded Discovery Status button to view the Discovery Information window.

Using VLAN Port Assignment

Table 4-2 lists the main tasks that you can perform using VLAN Port Assignment. All actions begin from the VLAN Port Assignment Main Window, unless otherwise specified. For more information about each task, see the VLAN Port Assignment online help.

Table 4-2 VLAN Port Assignment Tasks 

Task	Purpose	Action
Display all ports in a VTP domain.	Displays all ports in every VLAN that participates in a selected VTP domain.	1. From the VTP Domain drop-down list box, select a VTP domain. 2. Click Show All Ports.
Display specific ports in a VTP domain.	Searches for ports matching specific criteria.	1. From the VTP Domain drop-down list box, select a VTP domain. 2. From the Port Query panel, select search criteria from the drop-down list boxes and enter a search phrase in the text box. 3. Click Get Ports.
Display specific ports for a known device when the VTP domain name is not known.	Searches for ports on a device in an unknown VTP domain. You must know the device name or address to perform this search.	1. From the VTP Domain drop-down list box, select All. 2. In the Port Query panel, enter the device name or device address. 3. Click Get Ports.
Assign ports to VLANs.	Assigns ports to and moves ports between VLANs.	1. From the Ports Summary table, select the rows that contain the ports you want to move. You cannot move a trunking port. 2. From the drop-down list box in the Port Move panel, select the VLAN to which you are moving the ports. If you selected a port on a transparent switch, the VLAN must exist on that switch. 3. Click Move.
Configure trunk ports.	Assigns VLANs to trunking ports.	1. From the Ports Summary table, select the row that contains the trunking port. 2. Select Reports > Trunk Attributes. 3. Enter a range of ISL indices in the Allow VLAN(s) field and the Disallow VLAN(s) field to specify the VLANs that you want to allow and prevent on this trunk. If you enter indices in both fields, those indices are disallowed. 4. Click Apply to save your changes.
Find entries.	Searches for a specific entry or range of entries in the displayed Port Assignment table.	1. Select Edit > Find.... 2. In the Find dialog box, enter the search criteria. 3. Click Next for the next match below the selected row or Previous for a match above the selected row.
Display detail on a device with CiscoView.	Starts CiscoView to show details about a particular device.	1. From the Ports Summary table, right-click the row that contains the device. 2. Select CiscoView.
Telnet to a device.	Opens a remote terminal connection to a device.	1. From the Ports Summary table, right-click the row that contains the device. 2. Select Telnet. For more information on configuring telnet on Windows 2000, refer to How do I configure browser telnet?, page A-10.
Display a VTP domain in a network topology view.	Opens a view of a VTP domain in Topology Services.	1. If Topology Services is not already running, select Campus Manager > Topology Services from the CiscoWorks desktop. 2. From VLAN Port Assignment, select a row in the Ports Summary table. 3. Select View > Show VTP Domain.
Highlight all devices and links in a VLAN in a VTP domain network topology view.	Opens a view of a VTP domain in Topology Services with all devices and links in a VLAN highlighted.	1. If Topology Services is not already running, select Campus Manager > Topology Services from the CiscoWorks desktop. 2. From VLAN Port Assignment, select a row in the Ports Summary table. 3. Select View > Show VLAN.
Highlight a device in a VTP domain network topology view.	Opens a view of a VTP domain in Topology Services with a specific device highlighted.	1. If Topology Services is not already running, select Campus Manager > Topology Services from the CiscoWorks desktop. 2. From VLAN Port Assignment, select a row in the Ports Summary table. 3. Select View > Show Device.
Display port, device, or trunk attributes.	Displays information about the status of ports in your network.	1. From the Ports Summary table, select the row that contains the port. 2. Select Reports, then: –Port Attributes—For the status of ports in your network. – Device Attributes—For information on a specific device in your network. –Trunk Attributes—For the status for trunking ports in your network.

Frequently Asked Questions

Use the information in these sections to answer some common questions:

•Which ports carry voice traffic?

•Why did the operation to move a port fail?

Which ports carry voice traffic?

In the Ports Summary table, a port's association type signifies the kind of traffic it carries. A native association type means that the port carries data traffic. An auxiliary association type means that the port carries data and voice traffic.

Why did the operation to move a port fail?

From the Operation Completed window where the failure message appears, click the Details... button to find the reason for the failure.

Troubleshooting Suggestions

Use the information in the Troubleshooting VLAN Port Assignment Table 4-3 to troubleshoot the VLAN Port Assignment application.

Table 4-3 Troubleshooting VLAN Port Assignment

Symptom	Probable Cause	Possible Solution
VLAN Port Assignment starts, but shows an error message.	Server process is not running.	Confirm that the ANI Database engine and the ANI Server are running.
VTP Domain drop-down list box is empty and the following error message appears: Discovery seed not defined for ANI Server	A seed device is not specified for the ANI Server.	Add a seed device. Refer to the User Guide for CiscoWorks Common Services or the ANI Server online help for more information about adding a seed device.
VTP Domain drop-down list box is empty and the following message appears: ANI is still in the discovery process. Please wait..	The initial ANI discovery is not complete.	Wait for the ANI status bar to display Idle.
The message Operation Failure appears when you try to move a port.	The operation failed for one of various possible reasons.	Click the Details... button to display the cause of the failure.
