After making modifications to the $CVPNDIR/conf/cvpnd.

The cvpnd_restart command is used to restart the daemon after making modifications to the $CVPNDIR/conf/cvpnd.C file. The cvpnd daemon is responsible for managing the communication between the Check Point components and the Content Vectoring Protocol (CVP) server. The CVP server is an external server that provides content inspection and filtering services for Check Point gateways. The $CVPNDIR/conf/cvpnd.C file contains the configuration settings for the cvpnd daemon, such as the CVP server IP address, port number, timeout value, and debug level.
