8.8.1 Classification Precedence Rules
When there are multiple classifications assigned to a switch module, the switch module must
determine which classification takes precedence according to the Classification Precedence Rules.
The order of precedence is predefined in the switch module and cannot be changed.
Table 8-9 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.
3. This allows the classification of a packet, depending on if the udp/tcp socket falls within the range of the
user-entered “Start” and “End” values.
NOTE: It is important that you have a comprehensive understanding of the precedence
concept before configuring the switch module
, as these rules can have a significant
impact on the network operation.
