Description For the very slow data links, the seconds parameter must not be set too small.
Because the long datagram can only be transferred totally after a long time, the
transfer of keepalive datagram is delayed. The data link would be regarded to be
broken if the interface has not received the keepalive packet from the other end for
many keepalive periods. When the keepalive time is set to a very long time, the link is
considered broken by the other end, and then is closed.
At the two ends of a PPP link, the same keepalive interval is recommended.
