Is PEAP/EAP-MSCHAPv2 with certs a reasonable way to keep untrusted computers off the lan?

Hi Ivan,

I want machine security for machines owned by the school district.
That way only school machines can be on the Lan.
Student machines won't get the cert installed on their machines so
they won't be able to answer the challenge from the CA, right? Am I
missing your argument?

Is there some difference between a "machine cert" and a "client cert"
? If so is there some direction about how to manufacture and install

Sure, but again. Students can't just plug into those ports since they
won't have the cert that allows them access to the Lan, right?

I believe you. Assuming I collection of those switches wouldn't I also
need a management server to manage dynamic vlan assignment?
