Table 7-4. Setup Frame Buffer Format
Note that any mix of physical (i.e., unicast: the first bit of the address is 0) and logical
(i.e., multicast or group: the first bit of the address is 1) addresses can be used. Unused
addresses should be duplicated with one of the valid addresses.
Example of a Perfect Address Filtering Setup Frame
Figure 7-7 displays a perfect address filtering setup frame for two address filters.
