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).
The device is shipped with a default OAMP interface. For more information, see ''Default
OAMP IP Address'' on page 45. 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 32 interfaces, consisting of up to 31 Control and Media interfaces 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)

IP address (IPv4 and IPv6) and subnet mask (prefix length)

VLAN ID: You can enable VLAN functionality and configure a VLAN ID and the Native
VLAN ID (VLAN ID to which incoming, untagged packets are assigned). You can also
configure Quality of Service (QoS) by assigning VLAN priorities and Differentiated
Services (DiffServ) for the supported Class of Service (CoS). For configuring Quality
