Cisco Firepower 2100 User Manual

• You can only enable manager access on a physical, data interface. You cannot use a subinterface or
EtherChannel. You can also use the management center to enable manager access on a single secondary
interface for redundancy.
• 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.
High Availability Requirements
When using a data interface with device high availability, see the following requirements.
• Use the same data interface on both devices for manager access.
• Redundant manager access data interface is not supported.
• You cannot use DHCP; only a static IP address is supported. Features that rely on DHCP cannot be used,
including DDNS and low-touch provisioning.
• Have different static IP addresses in the same subnet.
• Use either IPv4 or IPv6; you cannot set both.
• Use the same manager configuration (configure manager add command) to ensure that the connectivity
is the same.
• You cannot use the data interface as the failover or state link.
End-to-End Tasks: Low-Touch Provisioning
See the following tasks to deploy the threat defense with CDO using low-touch provisioning.
