The Logical Interfaces section configures IP addresses (both IPv4 and IPv6) for the Ethernet ports and VLANs. Detailed description of the IP addresses for each of the

The third Ethernet port on the SBC 1000 is available only if running SBC 1000 v2 hardware and SBC Release 6.0.0 or later. For hardware details, see Sonus SBC 1000 Hardware Specifications.
When delivered from the factory, Ethernet 1 IP is enabled with DHCP by default, and an IPv4 address is acquired via a connected DHCP server. This IP address is used for performing Initial Setup on the SBC 1000. See Running Initial Setup for more information.
The default IP address for the logical interface named Ethernet 2 IP is 192.168.129.2. After initial configuration, you may configure this logical interface using Settings or Tasks tabs in the WebUI.
After initial configuration, a third logical interface named Ethernet 3 IP can be configured via Settings or Tasks tabs in the WebUI.
The IP addresses configured on the three logical interfaces and the VLAN interfaces are used for transporting all the VOIP media packets (e.g., RTP, SRTP) and all protocol packets (e.g., SIP, RTCP, TLS). DNS servers of the customer's network should map the

The Administrative IP port should be used for Running Initial Setup as well as all management related functionality from the web browser.

By default, each of the four Ethernet ports is set up to use its matching logical interface (e.g. Port Ethernet X uses Ethernet X IP) for IP layer communication, but this can be changed by configuring the VLAN settings on the Ethernet port.
When delivered from the factory, Ethernet 1 IP is enabled with DHCP by default, and an IPv4 IP address is acquired via a connected DHCP server. This IP address is used for performing Initial Setup on the
As described in the Managing VLANs section, each time a VLAN is created, a matching Logical Interface is also automatically created. This Logical Interface allows you to configure an IP address and have IP layer access for this VLAN. The configured IP address can be accessed through any Ethernet port that is associated with the given VLAN. VLAN Logical Interfaces behave the same as any other Logical Interface, and can be used for transporting VOIP media packets (e.g. RTP, SRTP), protocol packets (e.g. SIP, RTCP, TLS), and/or dynamic routing.
When a VLAN Logical Interface is first created, it will be disabled by default.
Logical interfaces support three modes of addressing: IPv4, IPv6, and Both (IPv4/IPv6). By default, Logical Interfaces are in IPv4 mode. When the Logical Interface is set for IPv4 mode, a Primary and Secondary IP address can be created. For IPv6, one primary IP Address can be statically configured.
For specific IPv4 and IPv6 configuration, see Configuring and Modifying Logical Interfaces.
In this example, the LAN uses IPv6, and the WAN uses IPv4. The
IPv6 to IPv4 Example
In this example, both the LAN and the WAN use IPv6. The SBC is responsible for serving as a back-to-back user agent between the two call legs. The DNS server and NTP server are both on the WAN.
IPv6 to IPv6 Example
In this example, the LAN uses IPv4 and the WAN uses IPv6. Just as in the IPv6-to-IPv4 case, the SBC is responsible for protocol interworking between the two call legs. The DNS server and the NTP server are both on the LAN.
IPv4 to IPv6 Example
The example below is shown for SBC 2000.
