Default Level

2: Configuration level

Usage Guidelines

If packets exceeding the threshold are sent to the IAE and their applications cannot be identified, the SA module identifies the application by port. A high threshold compromises the application identification performance while a low threshold increases the false positive rate. The default value (16) is recommended.


# Set the threshold of packet quantity for port identification in the SA module to 32.
