Hi everyone. I am just wondering what people think about the use of VLANs in a 100% Extreme network (B5 for wired and 5210 wireless)? I've heard things like VLANs are "old school" and there are better ways of doing things now with policy, NetSight, and NAC. I do believe policies are powerful tools for configuring and securing the network, but there is still that old idea of isolating traffic into separate broadcast domains for performance reasons. And dividing your network into subnets (VLANs) makes it easy to create policy and shape traffic on the firewall.
Are there any opinions out there? Should we be looking at a mix of both VLANs and policies? Are VLANS passé? I am new to Extreme Networks and policy-driven equipment so would very much welcome the feedback.
