Aprisa SR+ User Manual 1.5.3
L2 / L3 Protection Operation
The Aprisa SR+ Protected Station has selectable L2 Bridge or L3 Router modes, with VLAN, QoS and L2/3/4
address filtering attributes. Each Radio is configured with its own unique IP and MAC address and partner
radio address. On switch-over failure, the new active radio sends out a gratuitous ARP to update the MAC
learning tables / ARP tables of upstream bridge/router for appropriate traffic flow.
Hot-Swappable
The two Aprisa SR+ radios are mounted on a pull-out tray to making it possible to replace a failed radio
without interrupting user traffic.
