Configuring The Network Interfaces - Fortinet FortiVoice GO08 Administration Manual

For information about adding VLAN subinterfaces, see
page 25.
Redundant interfaces
On the FortiVoice Gateway, you can combine two or more physical interfaces to provide link
redundancy. This feature allows you to connect to two or more switches to ensure connectivity
in the event one physical interface or the equipment on that interface fails.
In a redundant interface, traffic is only going over one interface at any time. This differs from an
aggregated interface where traffic is going over all interfaces for increased bandwidth. This
difference means redundant interfaces can have more robust configurations with fewer possible
points of failure. This is important in a fully-meshed high availability (HA) configuration.
A physical interface is available to be in a redundant interface if:
• it is a physical interface, not a VLAN interface
• it is not already part of a redundant interface
• it has no defined IP address and is not configured for DHCP
• it does not have any VLAN subinterfaces
• it is not monitored by HA
When a physical interface is included in a redundant interface, it is not listed on the System >
Network > Network page. You cannot configure the interface anymore.
For information about adding redundant interfaces, see
page 25.
Loopback interfaces
A loopback interface is a logical interface that is always up (no physical link dependency) and
the attached subnet is always present in the routing table.
The FortiVoice Gateway's loopback IP address does not depend on one specific external port,
and is therefore possible to access it through several physical or VLAN interfaces. In the current
release, you can only add one loopback interface on the FortiVoice Gateway.
For information about adding a loopback interface, see
page 25.

Configuring the network interfaces

The System > Network > Network tab displays the FortiVoice Gateway's network interfaces.
You must configure at least one network interface for the FortiVoice Gateway to connect to your
network. Depending on your network topology and other considerations, you can connect the
FortiVoice Gateway to your network using two or more of the network interfaces. You can
configure each network interface separately. You can also configure advanced interface
options, including VLAN subinterfaces, redundant interfaces, and loopback interfaces. For more
information, see
