Deployment of a Standalone Device

The Ethernet ports on the E-SBC module can operate in pairs called Ethernet Groups to provide Ethernet port 1+1 redundancy. In each pair, one port serves as the active Ethernet port while the other as standby. When the active port fails, the device switches to the standby Ethernet port.

By default, the Ethernet ports are grouped into pairs, as shown below. However, you can change this port assignment, including assigning only a single port to an Ethernet Group. For more information, refer to the User's Manual.

Ethernet Port Pairs

It is important that the two ports making up a pair are connected to different switches (but in the same subnet). The following figure illustrates an example of implementing Ethernet-port redundancy:
