NDP Monitoring for Fast Device Location

The firewall now provides NDP monitoring. You can quickly track a device and user who has violated a security policy rule by viewing, in one location, the IPv6 addresses of devices on the link local network, their MAC address, associated username from User-ID (if the firewall has a User-ID mapping), reachability Status of the address, and Last Reported date and time the NDP monitor received a Router Advertisement from this IPv6 address. The username is on a best-case basis; there can be many IPv6 devices on a network with no username, such as printers, fax machines, servers, etc. You need the MAC address that corresponds to the IPv6 address in order to trace the MAC address back to a physical switch or Access Point.
NDP monitoring is not guaranteed to discover all devices because there could be other networking devices between the firewall and the client that filter out NDP or Duplicate Address Detection (DAD) messages. The firewall can monitor only the devices that it learns about on the interface.
NDP monitoring also monitors Duplicate Address Detection (DAD) packets from clients and neighbors. You can also monitor IPv6 ND logs to make troubleshooting easier.
NDP monitoring is supported for Ethernet interfaces, subinterfaces, Aggregated Ethernet interfaces, and VLAN interfaces on all PAN-OS models.
Enable NDP Monitoring and view information such as the IPv6 address of a neighbor the firewall has discovered, the corresponding MAC address, corresponding User ID (on a best-case basis), reachability Status of the address, and Last Reported date and time this NDP Monitor received an RA from this IP address.
