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 11-1: 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.
This page also provides VLAN-related parameters for enabling VLANs and defining the
Native VLAN ID. This is the 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 of Service (QoS), see 'Configuring the QoS Settings' on page
118 .
Complementing the Multiple Interface table is the IP Routing table, which allows you to
define static routing rules for non-local hosts/subnets. For more information, see
'Configuring the IP Routing Table' on page
115 .
