Mediant 4000B SBC
The following example shows an Ethernet Group comprised of ports 5 and 6, where Port 5
is connected to the main network ("LAN #1") and Port 6 to the redundant network ("LAN
#2"). Upon connectivity failure with LAN #1 through Port 5, the device connects to the
redundant LAN #2 through Port 6.

Deployment of Two Devices for High Availability
The device supports 1+1 high availability, whereby two devices are deployed and
connected to the same broadcast domain/s. In such a setup, the same Ethernet port-pair
redundancy setup is done for each device. For example, if port-pair 5 and 6 are used for
Device "A", then Device "B" must also use port-pair 5 and 6, as shown in the figure below:

In High Availability, the two devices interconnect through their Maintenance interfaces,
using the same Ethernet Port Group.
Note:
For possible connections (including Tx / Rx settings) between the HA devices,
