How to Configure Custom Virtual Interfaces
Create a custom virtual interface (CVI) to separate traffic on a particular interface and subnet from other traffic on the interface.
Follow these steps:
- Open the Active Interfaces page:
- Select Administration from the NFA console menu.
The Administration page opens.
- Select Interfaces: Physical & Virtual from the Administration menu.
The Active Interfaces page opens, which lists the current routers and their active interfaces.
- Expand the interface list for the parent router by clicking the arrow on the left.
- Select the check box next to an interface name.
The Add Custom Virtual Interface option is enabled.
- Click Add Custom Virtual Interface.
The Add Custom Virtual Interface dialog opens.
- Enter values for the following fields:
- Interface Name: Replace the default value in the Interface Name field with a meaningful name for the interface list.
Default: Parent interface name, which you must replace.
- Description: Enter a description to help identify the interface.
- In Speed and Out Speed: Identify the interface inbound and outbound data speeds.
- Type: Select the interface type from the list.
- Domain: Select a domain from the list or accept the default domain.
The Domain option is visible only in an environment that contains multiple domains.
- Subnet: Enter a subnet and mask identification for each subnet filter you want to use for this CVI, then click Add. Use the following format: <subnet IP address/subnet mask>
To be valid, the CVI must contain at least one subnet filter.
- Click Save when the settings in the Add Custom Virtual Interface dialog are complete.
The Custom Virtual Interface is automatically deployed within one minute. The Class icon for the new CVI distinguishes it from the physical interfaces.
Important! If you delete a parent CVI, all its children CVIs are deleted automatically.
