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
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.
