 Description
 -----------
 
-:program:`ndndump` is a traffic analysis tool that captures Interest, Data, and Nack packets on the
-wire and displays brief information about captured packets.
+:program:`ndndump` is a traffic analysis tool that captures NDN packets on the wire and
+displays brief information about them.
 
 Currently, :program:`ndndump` is capable of extracting Interest, Data, and Nack packets from:
 
-* Ethernet
+* Ethernet frame
 * PPP link (e.g., pcap trace from ndnSIM)
 * IPv4 UDP unicast tunnel
 * IPv4 UDP multicast group
-* IPv4 TCP tunnel, when Interest/Data/Nack is aligned to the front of a TCP segment
+* IPv4 TCP tunnel, when Interest/Data/Nack is aligned to the beginning of a TCP segment
+
+For more complex scenarios, including the case of NDN packets that span multiple IP fragments
+or multiple TCP segments, it is recommended to use the **NDN Wireshark dissector**, either via
+:manpage:`wireshark(1)` or :manpage:`tshark(1)`.
 
 Options
 -------
 
-.. option:: -h
+.. option:: -h, --help
 
     Print help and exit.
 
-.. option:: -V
+.. option:: -i INTERFACE, --interface=INTERFACE
 
-    Print version and exit.
-
-.. option:: -i INTERFACE
-
-    Listen on the specified interface.
+    Listen on *INTERFACE*.
     If unspecified, ndndump searches the system interface list for the lowest numbered,
     configured up interface (excluding loopback).
+    On Linux, a value of "any" can be used to capture packets from all interfaces.
+    Note that captures on the "any" pseudo-interface will not be done in promiscuous mode.
 
-.. option:: -r FILE
+.. option:: -r FILE, --read=FILE
 
-    Read packets from the specified file (which was created with :manpage:`tcpdump(8)` using its ``-w`` option).
+    Read packets from *FILE*, which can be created by :manpage:`tcpdump(8)` with its
+    ``-w`` option, or by similar programs.
 
-.. option:: -v
+.. option:: -f FILTER, --filter=FILTER
+
+    Print a packet only if its name matches the regular expression *FILTER*.
+
+.. option:: -p, --no-promiscuous-mode
+
+    Do not put the interface into promiscuous mode.
+
+.. option:: -v, --verbose
 
     Produce verbose output.
 
-.. option:: -f FILTER
+.. option:: -V, --version
 
-    Print a packet only if its Name matches the regular expression ``FILTER``.
+    Print ndndump and libpcap version strings and exit.
 
-.. option:: EXPRESSION
+.. option:: PCAP-FILTER
 
-    Selects which packets will be analyzed, in :manpage:`pcap-filter(7)` format.
-    If no :option:`EXPRESSION` is given, a default expression is implied which can be seen with ``-h`` option.
+    :option:`PCAP-FILTER` is an expression in :manpage:`pcap-filter(7)` format that
+    selects which packets will be analyzed.
+    If no :option:`PCAP-FILTER` is given, a default filter is used. The default filter
+    can be seen with the :option:`--help` option.
