This new feature allows you to drop new sessions from both the WAN and LAN side. This occurs when
the number of new sessions exceeds the maximum value set by you in a sampling time.

sessions are counted in the sampling time to check. (The default is 400 mil-sec.)

dropped after the number of new sessions exceeds it. (Default: 65535 session/sec)

that is acceptable in the sampling time. Any new incoming sessions will be dropped from
this host after the number of new sessions exceeds it. (Default: 100 session/sec)
 Maximum dropped sessions for host - If the number of dropped new sessions from the
host exceeds the Maximum in the sampling time, any new session from the host will be
dropped in the pause time period. (Default: 25 session/sec)

time period, no new session from the suspended host can be served by the system when the
