Configuring Ethernet Port Groups

The Ethernet Groups table lets you configure Ethernet Groups. An Ethernet Group
represents a physical Ethernet port(s) on the device. You can assign an Ethernet Group
with one, two, or no ports (members). When two ports are assigned to an Ethernet Group,
1+1 Ethernet port redundancy can be implemented in your network. In such a
configuration, one port can be active while the other standby or both ports can be active,
depending on the ports' transmit (Tx) and receive (Rx) settings. This provides port
redundancy within the Ethernet Group, whereby if a port is disconnected the device
switches over to the other port in the Ethernet Group. If you configure an Ethernet Group
with only one port, the Ethernet Group operates as a single port (no redundancy).
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 eight
Ethernet Groups where each contains one port, or four Ethernet Groups where each
contain two ports. By default, each Ethernet Group is assigned two ports; the other
Ethernet Groups are empty.
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 127). Then by assigning the Ethernet
Device to the IP network interface in the IP Interfaces table (see ''Configuring IP Network
Interfaces'' on page 129). 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 on page 122.
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.
•
Two different MAC addresses are assigned to the Ethernet ports: one to ports GE
1-4 (upper ports) and another to ports GE 5-8 (lower ports).
•
Ports with the same MAC address (e.g., GE 1-4 ports) must each be connected 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).
