Mediant 1000 Gateway & E-SBC | User's Manual
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. You
can assign one or two ports to an Ethernet Group. By default, each Ethernet Group is assigned
twoports (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.
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). Then by assigning the Ethernet Device to the IP network interface in the IP
Interfaces table (see Configuring IP Network Interfaces). 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).
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.
● The SWX LAN Expansion module is a customer-ordered item. For more
information, contact the sales representative of your purchased device.
● 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).
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).
➢ 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:
