Hi, is anyone using DHCP in their production network ?
We are tuning Option 82 feature of Radius right now, please provide feedback if you need it guys.
The Option 82 usage :
First scenario - Customer MAC/IP is linked to certain Switch + Port. When customer uses his device to connect to different port on Switch, he doesn’t get access. This can be setup for PPPoE as well.
Second scenario - Radius ignores MAC in DHCP request, and accepts all MAC addresses that are sent from defined Switch + Port value. It means - you connect customer to port and give him certain pool of IPs, Customer can connect router or switch to your equipment and there is no MAC filtering, just you enable port for user.
(In second scenario is good to have max. MAC on one port, Radius can limit it or Switch itself for example in Cisco switch it’s command switchport port-security maximum).
