We are using ISE for wireless corporate and guest access for some time with no problems. Now we are planning to expand access control to wired LAN. We plan to use web authentication with dynamic vlan assignment to both visitors and contractors. In our testing we have some problems with IP address renewing, since some browsers restrict java and others doesn´t support it at all. Anyone implemented a wired solution for Guest/Contractor access using ISE? Using dynamic vlan assignment for guests is a viable scenario?
