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 (see ''Default OAMP IP Address'' on
page 35). The IP Interfaces table lets you change this OAMP interface and configure
additional network interfaces for control and media, if necessary. You can configure up to
1,024 interfaces, consisting of up to 1,023 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 599.

IP address (IPv4 or IPv6) and subnet mask (prefix length)

To configure Quality of Service (QoS), see ''Configuring the QoS Settings'' on page
148.

Default Gateway: Traffic from this interface destined to a subnet that does not meet
any of the routing rules (local or static) are forwarded to this gateway

(Optional) Primary and secondary domain name server (DNS) addresses for resolving
FQDNs into IP addresses.

Ethernet Device: Layer-2 bridging device and assigned a VLAN ID. As the Ethernet
Device is associated with an Ethernet Group, this is useful for setting trusted and un-
