Configuring Virtual Scan Interfaces

You can define virtual scan interfaces and assign network views to them, and choose not to apply a network view to the physical LAN port hosting those virtual scan interfaces (LAN1, for example). You can also assign one network view to virtual scan interfaces on multiple collectors if necessary. 

You can create a virtual scan interface with a tagging value, but not immediately assign it to a network view. The virtual scan interface is effectively disabled and you can assign its network view at a later time. You can also assign it to an existing network view or create a new one.

To configure a virtual scan interface, complete the following:

1. Click the Settings icon > Setup > Scan Interfaces.
   The Scan Interfaces page appears, listing all device interfaces that may be used by the appliance. Depending on the hardware and system type, you will see one or more interfaces named MGMT and/or LANn (where n is the physical port number). If virtual scan interfaces are defined, they bear names such as LAN2.111.
2. Hover over the Action icon for any of the physical ports and select Add Virtual Scan Interface from the menu.
3. In Network View, choose one of the following:
   • Select Existing: Choose a network view from the list of existing ones that are defined on the system.
     • Select the view from the dropdown list.
     • Selecting Unassigned as the Network View leaves the interface in a disabled state.
   • Create New: Creates a new network view.
     • Enter the name for the new network view.
     • Enter a comment describing the view. These values can be edited at a later time.
4. In the Tag field, enter the 802.1Q tag value defined on the facing device that transits the trunk port or router port.
5. Enter IPv4 or IPv6 information, or both:
   • IPv4 Address: The IPv4 address for the scan interface.
   • IPv4 Subnet Mask:  The IPv4 subnet mask for the scan interface.
   • IPv4 Default Gateway: The IPv4 default gateway for the scan interface.
   • IPv6 Address: The IPv6 address for the scan interface.
   • IPv6 Subnet Mask: The IPv6 subnet mask for the scan interface.
   • IPv6 Default Gateway: The IPv6 default gateway for the scan interface.
6. In Primary DNS Server, specify the primary DNS server for the scan interface.
7. In Secondary DNS Server, specify the primary DNS server for the scan interface.
8. In Search Domains, specify valid hostnames separated by commas.
9. Click Save.

You can also edit or delete virtual scan interfaces.
