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.
