This document describes how to configure the Cisco L3 devices to forward DHCPv6 information to ISE for profiling purpose. Note that although Cisco IOS doesn’t support DHCPv6 via device sensor it still sends IPv6 via RADIUS accounting which is picked up by ISE in the IPv6 enabled network. There are two main ways to profile DHCPv6 at the time of this writing, one is to use DHCP relay feature on the router / L3 switch, and the other option is to use port SPAN on the PSN and monitor DHCP server interface. Below steps will allow ISE to learn DHCPv6 information in a IPv6 network using DHCP relay feature on the router / L3 switch.
