supports three system created logical interfaces (known as Ethernet 1 IP, Ethernet 2 IP, and Ethernet 3 IP) used to hold the IP addresses of the Ethernet ports 1, 2, and 3 respectively. In addition to the system created logical interfaces, the
also supports user created VLAN logical interfaces. VLAN logical interfaces are created each time a VLAN is added to the system. See About Logical Interfaces - VLAN Interfaces.| Info |

The third Ethernet port on the SBC 1000 is available only if running selected SBC 1000 hardware and SBC Release 6.0.0 or later. For hardware details, see Sonus SBC 1000 Hardware Specifications. |
Ethernet IP
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
system hostname to the configured IP addresses. The hostname or these IP addresses may be used by UC-enabling systems such as SIP-phones, IP-PBX and Microsoft Lync Servers and for accessing WebUI.| Info |

About Logical Interfaces - Sonus SBC 2000
The
supports five system created logical interfaces (known as Administrative IP, Ethernet 1 IP, Ethernet 2 IP, Ethernet 3 IP, and Ethernet 4 IP) used to hold the IP addresses of the Admin port and each of the four Ethernet ports (see Sonus SBC 2000 Front Panel). In addition to the system created logical interfaces, the Sonus SBC 2000 also supports user-created VLAN logical interfaces. VLAN logical interfaces are created each time a VLAN is added to the system, and are further described in the About Logical Interfaces - VLAN Interfaces.Administrative IP
The
system defines a logical interface called the Admin IP (Administrative IP, also known as the Management IP). This logical interface is used to hold the IP address of the Admin Ethernet port . A secondary IP address may be configured for this logical interface. The primary IP address is a factory-default IP address of 192.168.128.2/24 and it is used for running Initial Setup of the system.| Include Page |

Ethernet IP
The
system has one predefined logical interface for each of the four Ethernet ports. In most deployments, one of these logical interfaces (typically Ethernet 1 IP) and its assigned IP address is 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 system hostname to this IP address. The hostname or these IP addresses may be used by UC-enabling systems such as SIP-phones, IP-PBX and Microsoft Lync Servers and for accessing the WebUI.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
. See Running Initial Setup 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.About Logical Interfaces - SBC SWe Lite
The
supports five system created logical interfaces (known as Administrative IP, Ethernet 1 IP, Ethernet 2 IP, Ethernet 3 IP, and Ethernet 4 IP). In addition to the system created logical interfaces, the Sonus SBC SWe supports user-created VLAN logical sub-interfaces.Administrative IP
The
system supports a logical interface called the Admin IP (Administrative IP, also known as the Management IP). A Static IP or DHCP is used for running Initial Setup of the system.| Warning |
|---|
The Administrative IP interface should only be used for Running Initial Setup and disconnected when not in use (especially to avoid conflicts with your network). This interface cannot be used for VOIP media or protocols. |
Ethernet IP
The
system has four logical interfaces. In most deployments, one of these logical interfaces (typically Ethernet 1 IP) is assigned an IP address 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 system hostname to this IP address. The hostname or these IP addresses may be used by UC-enabling systems such as SIP-phones, IP-PBX and Microsoft Lync Servers and for accessing the WebUI.In the default software, Ethernet 1 IP is enabled and an IPv4 IP address is acquired via a connected DHCP server. This IP address is used for performing Initial Setup on the
. 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.About Logical Interfaces - VLAN interfaces
SBC Edge 1000-2000
As described in the Managing VLANs - SBC Edge 1000-2000 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.
| Note |
|---|
When a VLAN Logical Interface is first created, it will be disabled by default. |
SBC SWe Lite
VLAN sub-interfaces allow the separation of either management traffic between the service provider and the customer, or to keep media traffic from multiple sources separate (that need to exist on the same SWe Lite instance). For example, a service provider could use a VLAN to manage a SWe Lite at a customer premise, while also having a management interface for the customer; the service provider and the customer would be on the same physical network, but have separate logical interfaces.
When a VLAN sub-interface is configured, any IP traffic that uses that sub-interface will be VLAN tagged with the configured value.
VLAN sub-interfaces behave the same as any other Logical Interface, and are used for transporting VOIP media packets (e.g. RTP, SRTP), protocol packets (e.g. SIP, RTCP, TLS), and/or dynamic routing.
Configuration for each VLAN sub-interface is identical to the main interfaces (except the VLAN value is used to specify the interface as a sub-interface).
For configuring VLAN sub-interfaces, refer to Managing VLANs - SBC SWe Lite.
About Logical Interfaces - IPv4 and IPv6 Support
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.
IPv6 to IPv4 - Example
