6.3 Protocol VLAN

Protocol VLAN is another way to classify VLANs basing on network protocol. Protocol VLANs
can be sorted by IP, IPX, DECnet, AppleTalk, Banyan and so on. Through the Protocol VLANs,
the broadcast domain can span over multiple switches and the Host can change its physical
position in the network with its VLAN member role always effective. By creating Protocol
VLANs, the network administrator can manage the network clients basing on their actual
applications and services effectively.
This switch can classify VLANs basing on the common protocol types listed in the following
table. Please create the Protocol VLAN to your actual need.
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
Protocol VLANs.
Required. On the VLAN→MAC VLAN page, create the MAC VLAN.
For the device in a MAC VLAN, it's required to set its connected
port of switch to be a member of this VLAN so as to ensure the
normal communication.
