+# <addr>[/<port>[/<interval>[,ttl]]]
+# <addr>    IP address of the receiver
+# <port>    port UDP number of the receiver (default 2000)
+# <freq>    number of received datagrams between successive
+#           copied datagrams for this receiver.
+# <ttl>     The TTL (IPv4) or hop-limit (IPv6) for
+#           outgoing datagrams.
