Use the FTPKEEPALIVE statement to define the control connection keepalive timer value in seconds. This sets a socket level keepalive timer for the control connection. This allows the keepalive mechanism to send a packet on the idle control connection every FTPKEEPALIVE seconds, and avoid the firewall timing out the control connection.

Syntax

FTPKEEPALIVE 60 Usage notes
If you specify 0 seconds, the FTPKEEPALIVE timer is disabled and the only keepalive packets that flow on the control connection would be controlled by whatever interval for keepalive packets you have configured in the stack.
