Is there any resources that I could refer on if I want to do 802.1x & MAC
authentication for a particular user via Cisco Secure ACS 4.2? Our
management would like to have double authentication on the LAN whenever our
staff wants to connect to network, they will need to authenticate first via
802.1x and follows by MAC authentication after that. If 802.1x is ok but the
MAC authentication is failed then, the staff will not even able to connect
and they need to inform network administrator for help.

Hopefully any one of you able to give me advices and guide.

Thanks very much,

Regards,

Daniel
