Percentage of Max Sessions
, the
limit is the maximum number of sessions allowed from a single source machine as a
percentage of the total connection capacity. (Session Limit is a machine-based value.)
Otherwise, when the User Limit Parameter is set to

, the limit is an
absolute value.
Total Number of Packets Dropped due to Session Limit
: Shows total number of packets
dropped when session limit is reached.

Some protocols (such as FTP or RSTP) create two sessions per connection
which should be considered when configuring Session Limiting.
