We save S4 chaisis as core. And using one C5G124-24 per building as edge routers. And A4H series for access switches.
Our local partner said as a result of Extreme/Enterasys merge we should invest in summit X series instead of enterasys gears. X430 in place of A4H will be a good replace for us as it is 1G switch. But for our new building should we use X440? Do they have comparable parformance/features for our use case? We use dual stack ipv4 and ipv6 static routing on edge routers.
