SmartWare Software Configuration Guide
Enables IPsec debug monitor
Summarizes the configuration information of all
IPsec connections. If an IPsec connection does
not show up, then one or more parameters are
missing in the respective Policy Profile.
The information 'Bytes (processed)' supports
debugging because it indicates whether IPsec
packets depart from ('OUT') or arrive at ('IN') the
SmartNode.
