Command Usage
• When creating a protocol-based VLAN, do not assign interfaces to the
protocol VLAN via any of the standard VLAN commands. If you assign
interfaces using any of the other VLAN commands (such as vlan on
page 4-243), the switch will admit traffic of any protocol type into the
associated VLAN.
• When a frame enters the switch that has protocol VLANs configured, it is
processed in the following manner:
- If the frame is tagged, it will be processed according to the standard rules
1.
SNAP frame types are not supported by this switch due to hardware limitations.
