Configuring Traffic Filters and Protocol Prioritization
3-2
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.

Physical Medium
Bridge Encapsulation Method Supported
Ethernet 802.2 LLC LLC with SNAP Novell
Ethernet/802.3 Yes Yes Yes Yes
FDDI No Yes Yes No
Synchronous interface Yes Yes Yes Yes
Token Ring No Yes Yes No
