Table 6-2 Protocol types in common use
The packet in Protocol VLAN is processed in the following way:
1. When receiving an untagged packet, the switch matches the packet with the current
Protocol VLAN. If the packet is matched, the switch will add a corresponding Protocol
VLAN tag to it. If no Protocol VLAN is matched, the switch will add a tag to the packet
according to the PVID of the received port. Thus, the packet is assigned automatically to
the corresponding VLAN for transmission.
2. When receiving tagged packet, the switch will process it basing on the 802.1Q VLAN. If the
received port is the member of the VLAN to which the tagged packet belongs, the packet
will be forwarded normally. Otherwise, the packet will be discarded.
3. If the Protocol VLAN is created, please set its enabled port to be the member of
corresponding 802.1Q VLAN so as to ensure the packets forwarded normally.
