Figure 87: Displaying Protocol VLANs

Mapping Protocol

Groups to Interfaces

Use the VLAN > Protocol (Configure Interface - Add) page to map a protocol group
to a VLAN for each interface that will participate in the group.

Command Usage

◆

When creating a protocol-based VLAN, only assign interfaces using this
configuration screen. If you assign interfaces using any of the other VLAN
menus such as the VLAN Static table (

), these interfaces will admit

traffic of any protocol type into the associated VLAN.

◆

When a frame enters a port that has been assigned to a protocol VLAN, it is
processed in the following manner:

■

If the frame is tagged, it will be processed according to the standard rules
applied to tagged frames.
