Enable / disable the MAC filter.
6.6.2 Protocol Filter Menu Command
Protocol Selection
Without protocol filtering, the SCALANCE W 788 processes all data packets re-
gardless of the protocol being used. To increase data security and to reduce load,
it can nevertheless be useful to prevent communication using certain protocols.
Here, you are not restricted to the protocols included in the list in this menu. If nec-
essary, you can add your own entries to this list.
