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. 

On this page, you can create Protocol VLAN and view the information of the current defined
