8.3.2.3 Classification Precedence Rules
When there are multiple classification rules assigned to a switch, the device must determine which
classification rule takes precedence according to classification precedence rules. The order of
precedence is predefined in the switch and cannot be changed.
Table 8-3 lists classifications and associated precedence levels.
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.
NOTE: In Table 8-3 , the following applies:
- 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.
