I had some questions about how 802.1x protocol works.
I have read all I can but still have two questions:
1)What is a 'port' when referring to an access point? I know that for wired networks, switches have ports. But APs have no ports for each connection do they? So what stops any client from using the same virtual port as any other authenticated user? For example if A authenticates at virtual port 10, and then when B requests a connection it can access the same port right? If no, what i it spoofs A's MAC and IP addresses?
2)That leads to my second question. Once a client is authenticated, does it get an IP address through DHCP? If so, can't an attacker just eavesdrop and grab this IP address and access the network as well? What am I missing here?
Would appreciate any help from people who understand 802.1x better for wireless.
