Parameter Description
[PhysicalPortsTable_
GroupMember]
'Group Status'
group-status
[PhysicalPortsTable_
GroupStatus]
(Read-only) Displays the status of the port:
■ "Active": Active port. When the Ethernet Group includes two ports
and their transmit/receive mode is configured to 2RX 1TX or 2RX
2TX, both ports show "Active".
■ "Redundant": Standby (redundant) port.
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 12 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.
● 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).
