12.2 Configuring IP Network Interfaces
You can configure a single VoIP network interface for all applications, which includes
OAMP (management traffic), call control (SIP messages), and media (RTP traffic), or you
can configure multiple logical, IP network interfaces for these applications. A need often
arises to have logically separated network segments for these applications for
administration and security. This can be achieved by employing Layer-2 VLANs and Layer-
3 subnets.
The figure below illustrates a typical network architecture where the device is configured
with three network interfaces for the OAMP, call control, and media applications. The
device is connected to a VLAN-aware switch for directing traffic from and to the device to
the three separated Layer-3 broadcast domains according to VLAN tags (middle pane).
Figure 12-1: Multiple Network Interfaces
The Multiple Interface Table page allows you to configure these network interfaces. Each
row of the table defines a logical IP interface with the following attributes:

Application type allowed on the interface:
•
Control - call control signaling traffic (i.e., SIP)
•
Media - RTP traffic
•
Operations, Administration, Maintenance and Provisioning (OAMP) -
management (such as Web- and SNMP-based management)

IP address and subnet mask represented by prefix length

VLAN ID (if VLANs are enabled)

Default Gateway - traffic from this interface destined to a subnet that does not meet
any of the routing rules, local or static routes, are forwarded to this gateway (as long
this application type is allowed on this interface.

Primary and secondary DNS IP address (optional)
You can configure up to 16 interfaces, consisting of up to 15 Control and Media interfaces
and 1 OAMP interface.
