The Logical Interfaces section configures IP addresses for the Ethernet ports. Detailed description of the IP addresses for each of the UX platform is given below. To configure their physical layer settings of the Ethernet ports, go to Ports.

About Logical Interfaces - UX1000

Ethernet IP

UX1000 suppports two logical interfaces (known as an Ethernet 1 IP and Ethernet 2 IP) used to hold the IP address of the Ethernet ports 1 and 2 respectively (see item #8 on the UX1000 Front Panel).

When delivered from factory, Ethernet 1 IP has the default IP address of 192.168.128.2/24 (also referred to as 192.168.128.2/255.255.255.0). This is used for performing Initial Setup on the UX1000. See Running Initial Setup for more information.

There is no default IP address for the logical interface named Ethernet 2 IP. The operator may configure this logical interface using Settings or Tasks tabs on WebUI.

The IP addresses configured on the two logical 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 UX 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 UX WebUI.

About Logical Interfaces - UX2000

UX2000 supports two logical interfaces, named Administrative IP and Application IP.

Administrative IP

UX2000 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 (see item #7 on the UX2000 Front Panel). 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 UX system.

The Administrative IP port 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.

Application IP

The UX system has a predefined logical interface known as an Application IP. In most deployments, this logical interface and its assigned 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 UX 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 UX WebUI.

By default, the first three LAN Ethernet ports (LAN1, LAN2 and LAN3) are placed in the switched-mode, and as part of the Application-Bridge. This IP address is used on all those Ethernet ports. All hosts connected to any of these three LAN ethernet ports must be configured in the same IP subnet as the Application IP. The fourth Ethernet port (LAN4) is placed as part of Bridge Two by default.

When two or more LAN Ethernet ports are on the same Bridge (as in the factory-default UX configuration), they must not be connected to the same Ethernet switch or Ethernet network. Doing so creates a broadcast loop in the Ethernet network, rendering the network unusable. You may work around this issue by connecting the Ethernet ports directly to an intelligent switch or router running a spanning tree protocol.

Bridging

The Application IP interface is automatically associated with the first of five internal bridges, the Application Bridge, which are available to any LAN port configured to operate in the switched mode.

Managing Logical Interfaces

  1. In the WebUI, click the Settings tab.
  2. In the left navigation pane, go to Node Interfaces > Logical Interfaces.

To view an interface's properties:

  1. Click the popup() icon next to the entry you want to view.
  2. When you are finished, close the window.

Helpful Tip: To delete an entry, simply select the checkbox next to the entry you wish delete, then click the Delete () icon located at the top of the window.
