Classification Precedence Rules

NOTE: It is important that you have a comprehensive understanding of the precedence
concept before configuring the switch, as these rules can have a significant impact on
the network operation.
When there are multiple classifications assigned to a switch, the switch must determine which
classification takes precedence according to the Classification Precedence Rules. The order of
precedence is predefined in the switch and cannot be changed.
Table 9-8 lists the ISO Layer, associated classification and precedence levels.
NOTE: In
– Highest precedence is 1a.
– Lowest precedence is 6.
– Exact Match indicates a match of an explicitly defined address.
– Best Match indicates a match of an entire subnet, or range of addresses within a
subnet.
