User-Deﬁned Transparent Bridge Criteria

You can create bridge trafﬁc ﬁlters with user-deﬁned criteria by specifying an

offset and length to these reference ﬁelds:

Transparent Bridge Actions

In addition to the Accept, Drop, and Log actions that are common to all the

protocols, there are two Bridge-speciﬁc actions:

• Flood

Speciﬁes that any frame that matches the ﬁlter will be forwarded onto all

Bridge circuits except for the circuit from which it was received.

• Forward to Circuit List

Speciﬁes that any frame that matches the ﬁlter will be forwarded to certain

circuits that you specify.
