6.2 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.
Protocol Type Type value
ARP 0x0806
IP 0x0800
MPLS 0x8847/0x8848
IPX 0x8137
IS-IS 0x8000
LACP 0x8809
802.1X 0x888E
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.
