No, ip-helpers are configured on the VLAN, not on the port or authenticated user.
The DNS server for the switch itself is a global setting for the switch, and the DNS server for the user is normally delivered through DHCP (and the ip-helper just covered) based on the VLAN that a client is placed in (which can be DUR). The switch or ClearPass don't have anything to do with that.

Subject: Sending back information with DUR's
Hello everyone,
I am a student and currently working on a IT infrastructure for a company. I have a question about the DUR's (Downloadable User Roles) that you can use to send back information to a switch or access point. I know that you can send back information about, for example, Vlan id / name. But is it also possible to send back information to a switch like; ip-helper or a dns-server?
What I want to achieve, is that when a client is connecting to a switch, that clearpass sends back all the information needed for the port. (Vlan id; IP-helper; DNS-server; etc).
So my question is: Is it possible to send back information like ip helper-address x.x.x.x (For DHCP) and dns-server x.x.x.x?
kind regards,
Jeffrey Mik
