VLAN Classification Configuration Screen
802.1Q VLAN Configuration Menu Screens

The following example shows how the precedence concept can be applied:
Example
A network administrator has defined the following two classifications involving VLANs:
All frames with a UDP Port Source number of 55 (Layer 4, precedence level 4a) are assigned to 
the Red VLAN.
All frames sourced from the 134.141.28.xx subnet (Layer 3, Source IP Address Best Match, 
level 2b) are assigned to the Blue VLAN.
In this example, a frame that is received with a source address of 134.141.28.99 and contains a 
UDP port number of 55 will be assigned to the Blue VLAN because a Layer 3 IP Address rule 
takes precedence over a Layer 4 rule.
The key thing to remember is that the SmartSwitch devices will classify frames based on one of 
the classification options.

Displaying the Current Classification Rule Assignments
To see which ports are set to a particular Classification Rule, the Protocol Port Configuration 
screen must be displayed. 
To access the Protocol Port Configuration, proceed as follows:
1. Use the arrow keys to highlight the line with the Classification Rule of interest. 
2. Press ENTER. The Protocol Port Configuration screen displays, showing all ports and those 
associated with the Classification Rule selected in Step 1. These ports are identified on the 
screen by a YES setting in the Classify columns. For more information about the Protocol Port 
Configuration screen and how to use it, refer to
