2 Create VLAN. Required. On the VLAN→802.1Q VLAN→VLAN Config page,click the Create button to create a VLAN. Enter the VLAN ID andthe description for the VLAN. Meanwhile, specify its memberports.3 Modify/View VLAN. Optional. On the VLAN→802.1Q VLAN→VLAN Config page,click the Edit/Detail button to modify/view the information of thecorresponding VLAN.4 Delete VLAN Optional. On the VLAN→802.1Q VLAN→VLAN Config page,select the desired entry to delete the corresponding VLAN byclicking the Delete button.6.2 Protocol VLANProtocol VLAN is another way to classify VLANs basing on network protocol. Protocol VLANs canbe sorted by IP, IPX, DECnet, AppleTalk, Banyan and so on. Through the Protocol VLANs, thebroadcast domain can span over multiple switches and the Host can change its physical positionin the network with its VLAN member role always effective. By creating Protocol VLANs, thenetwork administrator can manage the network clients basing on their actual applications andservices 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 valueARP0x0806IP0x0800MPLS0x8847/0x8848IPX0x8137IS-IS0x8000LACP0x8809802.1X 0x888ETable 6-2 Protocol types in common useThe packet in Protocol VLAN is processed in the following way:1. When receiving an untagged packet, the switch matches the packet with the current ProtocolVLAN. If the packet is matched, the switch will add a corresponding Protocol VLAN tag to it. Ifno Protocol VLAN is matched, the switch will add a tag to the packet according to the PVID ofthe received port. Thus, the packet is assigned automatically to the corresponding VLAN fortransmission.2. When receiving tagged packet, the switch will process it basing on the 802.1Q VLAN. If thereceived port is the member of the VLAN to which the tagged packet belongs, the packet willbe forwarded normally. Otherwise, the packet will be discarded.3. If the Protocol VLAN is created, please set its enabled port to be the member ofcorresponding 802.1Q VLAN so as to ensure the packets forwarded normally.59
