3. 6 2 MAC VLAN MAC VLAN technology is the way to classify VLANs according to the MAC addresses of Hosts A MAC address corresponds to a single VLAN ID For the device in a MAC VLAN if its MAC address is bound to VLAN the device can be connected to another member port in this VLAN and still takes its member role effect without changing the configuration of VLAN members The packet in MAC VLAN is processed in the following way 1 When receiving an untagged packet the switch matches the packet with the current MAC VLAN If the packet is matched the switch will add a corresponding MAC VLAN tag to it If no MAC 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 based 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 Ifthe MAC address of a Host is classified into 802 1Q VLAN please set its connected port of switch to be a member of this 802 1Q VLAN so as to ensure the packets forwarded normally On this page you can create MAC VLAN and view the current MAC VLANs in the table Choose the menu VLAN MAC VLAN to load the following page Create MAC VLAN MAC Address Format 00 00 00 00 00 01 Crea

5. 3 Create MAC VLAN Required On the VLAN gt 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 6 3 Protocol VLAN Protocol VLAN is another way to classify VLANs based 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 based on their actual applications and services effectively Protocol VLAN another way to classify VLANs based on network protocol can bind ToS provided in the network to VLAN to realize the specific service Through protocol VLAN the switch can analyze the received un VLAN tagged packets on the port and match the packets with the user defined protocol template according to different encapsulation formats and the values of the special fields If a packet is matched the switch will add a corresponding VLAN tag to it automatically and thus the data of specific protocol can be automatically assigned to the corresponding VLAN for transmission The network administrator can manage network clients based on their specific applications and services through protocol VLAN 56
