man 8 isakmpd:

%%%
     -L      Enable IKE packet capture.  When this option is given, isakmpd
             will capture to file an unencrypted copy of the negotiation pack-
             ets it is sending and receiveing.  This file can later be read by
             tcpdump(8) and other utilities using pcap(3).
