AES-256 encryption is available via Licence key upgrade, but only in countries where regulations permit, and
only on units already fitted with AES-capable hardware (some Single-port and all Dual-port versions).
Maximum encrypted capacity is 700Mbps full-duplex.

2.2 Ethernet Switch
Each radio terminal includes an Ethernet switch. The first switch port is connected to the physical Ethernet
connection to the terminal. The second switch port is connected to the radio modem and the terminal’s
management agent.
The switch transparently passes all Layer 3 protocol messages. For example, the switch does not implement
any kind of Spanning Tree Protocol (STP): it will simply pass all STP messages transparently over the air, but
will not perform any routing of data traffic based on the Spanning Tree. This means that all incoming packets
on the Ethernet interface are simply passed over the air, without taking any account of STP, and therefore the
installer should ensure that there are no data loops in the system, because the switch will not detect the
existence of a loop.
The single-port version of Liberator-V1000 does not support MAC address learning, but simply re-directs
packets that are addressed to the management agent. All other packets are sent over the radio.
In the dual-port version of Liberator-V1000, the switch is capable of learning up to 1024 MAC addresses to
switch between the 2 ports. Any packets addressed to the management agent are redirected, and all other
packets are sent over the radio.
