◆ 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 ( page 202 ), 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.
■
If the frame is untagged and the protocol type matches, the frame
is forwarded to the appropriate VLAN.
■
If the frame is untagged but the protocol type does not match, the
frame is forwarded to the default VLAN for this interface.
