For the interface where you enabled NDP monitoring,
in the Features column, hover over the
NDP
Monitoring icon.
The NDP Monitoring summary for the interface displays the
list of IPv6 Prefixes that this interface
will send in the Router Advertisement (RA) if RA is enabled (they
are the IPv6 prefixes of the interface itself).
The summary
also indicates whether DAD, Router Advertisement, and DNS Support
are enabled; IP addresses of any Recursive DNS Servers configured; and
any DNS suffixes configured on the DNS Search List.
Click on the NDP Monitoring icon to display detailed
information.
Each
row of the detailed NDP Monitoring table for the interface displays
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. A
User ID will not display for printers or other non-user-based hosts.
If the status of the IP address is Stale, the neighbor is not known
to be reachable, per RFC 4861.
At the bottom right is the
count of Total Devices Detected on the link
local network.
