Protocol VLAN Configuration
To complete protocol VLAN configuration, follow these steps:
1)  Configure 802.1Q VLAN.
2)  Create protocol template.
3)  Configure Protocol VLAN.
Configuration Guidelines
 ■ You can use the IP, ARP, RARP, and other protocol templates provided by TP-Link 
switches, or create new protocol templates.
 ■ In a protocol VLAN, when a port receives an untagged data packet, the switch will first 
search for the protocol VLAN matching the protocol type value of the packet. If there 
is a match, the switch will insert the corresponding VLAN tag to the data packet and 
forward it within the VLAN. Otherwise, the switch will forward the data packet to the 
default VLAN based on the PVID (Port VLAN ID) of the receiving port. (If MAC VLAN is 
also configured, the switch will first process Protocol VLAN, then MAC VLAN.) When 
the port receives a tagged data packet, the switch will directly process the data packet 
according to the processing rule of the 802.1 Q VLAN.

2.1.1  Configuring 802.1Q VLAN
Before configuring protocol VLAN, create an 802.1Q VLAN and set the port type according 
to network requirements. For details, refer to Configuring 802.1Q VLAN.
