ZXR10 3900 Series Switches Running the ZXROS Operating System
The TOE is a 3900 series ESS running the operating system ZXROS 4.08.
An ESS is a device with Layer-2 switch and offers Layer-3 capabilities. As a Layer 2
switch it analyzes incoming frames, makes forwarding decisions based on
information contained in the frames, and forwards the frames toward the
destination. The layer-3 enabled switch supports routing of the traffic. ESSs may
create or maintain a table of the available routes and their conditions and use this
informat ion along wi th distance and cost algorithms to determine the best route for
a given packet . Routing protocols include BGPv4, RIPv2 and OSPFv2.
