Transparent Bridge Criteria and Actions

Bridge ﬁlters are the most complex, because they support multiple encapsulation

methods and media types. Table 3-1 shows the encapsulation methods supported

on physical media types.

You ﬁlter inbound transparent bridge frames based on header ﬁelds within each of

the four supported encapsulation methods:

• Ethernet

• IEEE 802.2 logical link control (LLC)

• IEEE 802.2 LLC with Subnetwork Access Protocol (SNAP) header

• Novell Proprietary

Each transparent bridge encapsulation method has speciﬁc, predeﬁned criteria for

ﬁltering frames. Figure 3-1 illustrates the header content of each supported

encapsulation method.
