Using the Configuration Management VLAN Manager

Configuration Management VLAN Manager (SETTINGS menu > Configuration Management > VLAN Manager) enables easy and dynamic update of VLAN configurations. Through the VLAN Manager, you can add, edit, and delete VLANs from individual devices. You can also take advantage of VLAN Trunking Protocol (VTP) enabled by Cisco switches where updating VLAN properties on one device triggers VLAN database refresh on other devices. Otherwise, you can copy and move single or multiple VLAN specifications from one network device to other VLAN-capable network devices.

Important: Devices in WhatsUp Gold must have proper read/write credentials assigned before you can apply VLAN specification changes. Some switches/routers allow configuration using SNMP, in other cases you will need SSH or Telnet credentials (that enable WhatsUp Gold to run system scripts) to apply VLAN configuration changes.

VLAN Manager Guidelines

To manage device VLAN configurations, consider the following:

• For Cisco devices, your device must support the Cisco VTP MIB.
• If you want to take advantage of automatic distribution of changes to other VTP-enabled devices on your network, the device you choose to modify must be running in VTP server mode.
• VLAN Manager operations that execute by way of SSH/Telnet will exercise system scripts that you can customize.

  Note: Cisco VTP-enabled devices run in VTP server mode by default.

Tip: For more information on Cisco trunking, see Cisco's documentation and read Understanding VTP.

To configure device VLANs using the VLAN Manager:

1. Click Select Device... to choose a device from the Select Device dialog.
2. Click Discover to discover and view the VLAN configuration for the selected device. The discovered VLAN information is displayed in the VLANs section of the dialog.
3. In the VLANs section of the dialog, configure VLAN for the switch:
   • Add. Add a VLAN to the switch configuration.
   • Edit. Edit a VLAN name property for the switch configuration.

   Note: You cannot edit the VLAN Index. If you want to modify a VLAN's index number, you must delete the VLAN and add the VLAN again with the desired index number. You cannot edit VLANs that are reserved by the switch vendor. For example, you cannot use default VLANs or Cisco Reserved VLAN indexes (1000-1024).

   • Delete. Remove the VLAN property from the device.

   Note: You will be prompted before you remove a VLAN from a device.

   • Copy To. Copy the selected VLAN to duplicate the VLAN Name/Index configuration to another VLAN capable device.
   • (Bulk actions) select VLANs and then click the operation you want to perform in bulk. For example, you can copy complete VLAN specifications to a backup or temporary device.
4. In the Port VLAN Configuration section of the dialog, configure VLAN port assignments, and/or commit configuration changes.
   • Select a VLAN switch port, then click Assign To to set the static (primary) VLAN ID.
   • Select a VLAN switch port, then click Add/Edit Trunk to modify its Trunk configuration tags.
   • Select a VLAN switch port, then click Remove Trunk to return the port to its default, non-trunking configuration.
   • Select multiple VLAN switch ports, then click Bulk Action > Assign To to set the static (primary) VLAN ID.
5. Click Commit Changes to copy the currently running config of the selected device to the startup config.
6. Click Close to exit the dialog.
