IP device tracking for connected hosts in non-DHCP environments

This feature enables IP Device Tracking to monitor and report host IP addresses on 802.1X-authenticated ports in environments where DHCP snooping is not deployed. It provides enhanced visibility and control for statically addressed clients by allowing administrators to enforce IP-based policies via a RADIUS server. The 802.1X control plane dynamically learns MAC-IP bindings from Layer 2 MAC-IP snooping events and includes the learned IP address as the Framed-IP-Address attribute in interim accounting updates. This capability improves endpoint tracking and supports more granular policy enforcement in non-DHCP network environments.
