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 Ribbon 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

About Logical Interfaces - VLAN interfaces
SBC Edge 1000-2000
As described in the Managing VLANs - SBC 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.
When a VLAN Logical Interface is first created, it will be disabled by default.
SBC SWe Edge
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 Edge instance). For example, a service provider could use a VLAN to manage a SWe Edge 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 Edge
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
In this example, the LAN uses IPv6, and the WAN uses IPv4. The
IPv6 to IPv6 - 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.
IPv4 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.
Managing Logical Interfaces
The example below is shown for SBC 2000.
- In the WebUI, click the Settings tab.
In the left navigation pane, go to Node Interfaces > Logical Interfaces (Networking Interfaces > Logical Interfaces for SWe Edge)
To view an interface's properties:
- Click the pop-up icon ( ) next to the entry you want to view.
- When you are finished, close the window.
To delete an entry, select the checkbox next to the entry and then click the Delete (
) icon.Logical Interfaces and Redundant Ethernet Pairs
If the logical interface is part of a redundant Ethernet pair, several of the options on the secondary logical interface will become read-only.
