Non-Mobile Groups And Autotracker Vlans; Routing In A Non-Mobile Group - Alcatel Omni Switch/Router User Manual

Non-Mobile Groups and AutoTracker VLANs

Non-mobile Groups are comprised of physical entities—switch ports. Groups can span multi-
ple switches, but they are still made up of physical ports that you can see and touch. But just
as physically-based broadcast domains are limited, entirely port-based Groups can also be
limiting. In a large, flat, switched network, broadcast traffic can overload the network. There
needs to be a method for subdividing traffic even further. That's where virtual networks, or
VLANs, come into play.
s are created within a Group to subdivide network traffic based on specific criteria. The
