When creating a protocol-based VLAN, only assign interfaces via this
◆
command. If you assign interfaces using any of the other VLAN
commands (such as the
traffic of any protocol type into the associated VLAN.
When MAC-based, IP subnet-based, and protocol-based VLANs are
◆
supported concurrently, priority is applied in this sequence, and then
port-based VLANs last.
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.
