User's Manual 12. Network
The Ethernet Groups table also lets you configure the transmit (Tx) and receive (Rx)
settings of the Ethernet ports per Ethernet Group. The Tx/Rx setting is applicable only to
Ethernet Groups that contain two ports. This setting determines whether either both ports
or only one of the ports can receive and/or transmit traffic.
The maximum number of Ethernet Groups that you can configure is the same as the
number of Ethernet ports provided by the device. Thus, the device supports up to seven
Ethernet Groups where each contains one port, or up to three Ethernet Groups where each
contains two ports (Ethernet Group 2 which is assigned only port 0/3); the other Ethernet
Groups are empty. For default port assignment to Ethernet Groups, see Configuring
Physical Ethernet Ports on page 134.
You can assign Ethernet ports to IP network interfaces. This is done by first configuring an
Ethernet Device with the required Ethernet Group containing the port or ports (see
''Configuring Underlying Ethernet Devices'' on page 139). Then by assigning the Ethernet
Device to the IP network interface in the IP Interfaces table (see ''Configuring IP Network
Interfaces'' on page 142). This enables physical separation of network interfaces, providing
a higher level of segregation of sub-networks. Equipment connected to different physical
ports is not accessible to one another; the only connection between them can be
established by cross connecting them with media streams (VoIP calls).
Note: The SWX LAN Expansion module is a customer-
information, contact your AudioCodes sales representative.
The port names (strings) displayed in the Ethernet Groups table represent the physical
ports on the device. For the mapping of these strings to the physical ports, see Configuring
Physical Ethernet Ports on page 134.
The following procedure describes how to configure Ethernet Groups through the Web
interface. You can also configure it through ini file (EtherGroupTable) or CLI (configure
network > ether-group).
Note:
• If you want to assign a port to a different Ethernet Group, you must first remove
the port from its current Ethernet Group. To remove the port, configure the
'Member' field so that no port is selected or select a different port.
• As all ports have the same MAC address, you must connect each port to a
different Layer-2 switch.
• When implementing 1+1 Ethernet port redundancy, each port in the Ethernet
Group (port pair) must be connected to a different switch (but in the same subnet).
To configure Ethernet Groups:
1. Open the Ethernet Groups table (Setup menu > IP Network tab > Core Entities
folder > Ethernet Groups).
2. Select the Ethernet Group that you want to configure, and then click Edit; the following
dialog box appears:
