Application filters allow key applications to have prioritized access to bandwidth. These filters ensure mission critical applications have adequate performance during times of high congestion. Application filters allow you to manage policy around non-productive or potentially illegal applications. Initially this includes Peer-to-Peer management, where the user may apply block or shape actions across the category or on an individual basis. These filters block traffic depending on the configured actions for a filter.
