Protocol VLAN, 7.5.1 Protocol Group Table

Page 88 highlights

7.5 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 ARP IP MPLS IPX IS-IS LACP 802.1X Type value 0x0806 0x0800 0x8847/0x8848 0x8137 0x8000 0x8809 0x888E Table 7-2 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. 7.5.1 Protocol Group Table On this page, you can create Protocol VLAN and view the information of the current defined Protocol VLANs.

7.5 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.
