7.8.1 Classification Precedence Rules
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.
Tabl e 7-9 lists the ISO Layer, associated classification, and precedence levels.

1. Bold type indicates a user entry.
2. Any fragmented IP frame received is Classified to the priority identification (PID) and
forwarded out the ports configured in the Protocol Port Configuration screen.

user-entered “Start” and “End” values.
NOTE: It is important that you have a comprehensive understanding of the preced ence
concept before configuring the SmartSwitch device, as these rules can have a
significant impact on the network operation.
NOTE: In Tab le 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.
