Using the Threat Defense Data Interface for Management

You can use either the dedicated Management interface or a regular data interface for communication with the management center. Manager access on a data interface is useful if you want to manage the threat defense remotely from the outside interface, or you do not have a separate management network.

Manager Access Requirements

Manager access from a data interface has the following requirements.

• You can only enable manager access on one physical, data interface. You cannot use a subinterface or EtherChannel, nor can you create a subinterface on the manager access interface.

• This interface cannot be management-only.

• Routed firewall mode only, using a routed interface.

• PPPoE is not supported. If your ISP requires PPPoE, you will have to put a router with PPPoE support between the threat defense and the WAN modem.

• The interface must be in the global VRF only.

• SSH is not enabled by default for data interfaces, so you will have to enable SSH later using the management center. Because the Management interface gateway will be changed to be the data interfaces, you also cannot SSH to the Management interface from a remote network unless you add a static route for the Management interface using the configure network static-routes command.

• Clustering is not supported. You must use the Management interface in this case.
