7.8.1Classification Precedence Rules

NOTE: It is important that you have a comprehensive understanding of the precedence concept before configuring the SmartSwitch device, as these rules can have a significant impact on the network operation.

When there are multiple classifications assigned to a SmartSwitch device, the SmartSwitch device must determine which classification takes precedence according to the Classification Precedence Rules. The order of precedence is predefined in the SmartSwitch device and cannot be changed.

Table 7-9lists the ISO Layer, associated classification, and precedence levels.

NOTE: In Table 7-9,the following applies:

- 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.
