Enabling or Disabling Hardware Filtering

When you add an Ethernet circuit for a link or net module with hardware ﬁlter

capability, Site Manager displays the prompt

Do you want to enable Hardware Filters on this circuit?

Hardware ﬁltering is disabled by default, but changes to enabled if you reply OK

to this prompt.

With hardware ﬁltering enabled, the Ethernet interface drops local frames instead

of copying them into router memory to be processed. Local frames are frames that

contain both destination and source MAC addresses that the router has learned on

this Ethernet interface. Bridge software teaches the hardware ﬁlter which MAC

addresses are local to an interface.

Enabling hardware ﬁltering improves bridging software performance, because the

router does not need to determine whether to receive and reject local frames.

You can enable or disable hardware ﬁltering. Set to Enable only if the link or net

module has hardware ﬁlters and you enabled the bridge software.
