You can click multiple checkboxes to select multiple traps to exclude from this de-duplication rule.
Each trap is listed in the Unfiltered Duplicate Traps field.
• Length of Time Window: Defines the length of time in minutes in which traps would be considered
duplicate. Enter the time in minutes. The default is 10 minutes.
• Length of Trap Queue: Defines the maximum number of traps that are kept by IMC. Traps in the trap
queue are matched against incoming traps to determine if there is a duplicate trap match. A long
trap queue length ensures that the filter catches more traps and a shorter trap queue length reduces
the number of traps filtered by this filter. The default is 5000 trap entries. The minimum is 100 and
the maximum is 10000.
17. Click the Use Sliding Time Window checkbox if you want a sliding window time counter
applied to the length of time window for this filter rule.
