I have configured MAB (MAC Authentication Bypass) with MDA (Multi Domain Access). All devices are successfully authenticating with their respective VLAN. MAB devices got authenticating as Voice.
I am using ACS (Radius) for authentication and DHCP relay.
Problem is voice device is not getting IP from DHCP server. There is no error reporting on switch and radius. Without Dot1x everything is working.
