12.4 Configuring IP Network Interfaces
You can configure a single VoIP network interface for all applications, including OAMP
(management traffic), call control (SIP signaling messages), and media (RTP traffic), or
you can configure multiple logical, IP network interfaces for these applications. You may
need to 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, each representing 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 12-4: Multiple Network Interfaces
The device is shipped with a default OAMP interface. For more information, see ''Default
OAMP IP Address'' on page 25. The Interface table lets you change this OAMP interface
and configure additional network interfaces for control and media, if necessary. You can
configure up to 48 interfaces, consisting of up to 47 Control and Media interfaces including
a Maintenance interface if your device is deployed in a High Availability (HA) mode, and 1
OAMP interface. Each IP interface is configured with the following:
Application type allowed on the interface:
• Control: call control signaling traffic (i.e., SIP)
• Media: RTP traffic
• Operations, Administration, Maintenance and Provisioning (OAMP): management
(i.e., Web, CLI, and SNMP based management)
• Maintenance: This interface is used in HA mode when two devices are deployed
for redundancy, and represents one of the LAN interfaces or Ethernet groups on
each device used for the Ethernet connectivity between the two devices. For
more information on HA and the Maintenance interface, see Configuring High
Availability on page 402.
