The limit or trigger describes a quantified threshold value that must be exceeded on the defined connection before the filter action gets executed for a data packet. A limit is composed by the following parameters:
- Unit (kbit, kbyte or packets)
- Amount, that means data rate or number.
- Reference value (per second, per minute, per hour or absolute)
Additionally, you can adjust for the limit whether it refers to a logical connection or to all connections together, which exist between the defined destination and source stations via the corresponding services. Thus it is controlled whether the filter takes effect, if e.g. all HTTP connections of the users in the LAN exceed the limit in sum, or whether it is sufficient that only one of the parallel established HTTP connections exceeds the threshold value.
For absolute values it is additionally possible to specify whether the counter belonging to it will be reset to zero when the limit has been reached.
