Ieee8021qFilter | compound module |
This module implements the IEEE 802.1Q per-stream filtering and policing. The relationship between streams, gates and meters is not one-to-one. The number of streams, gates and meters can be different and the module will take care about the connections between the submodules based on the streamFilterTable parameter. |
