Today, I'd like to share with you a knowledge point. The details are as follows:
Standard VLAN | It is a standard VLAN. Ethernet ports in a standard VLAN can communicate with each other. An Ethernet port in a standard VLAN is isolated from an Ethernet port in another standard VLAN. | The standard VLAN is only used for Ethernet ports for network management and subtending. |
Smart VLAN | A smart VLAN can contain multiple xDSL service ports and traffic streams of these ports in a smart VLAN are isolated from each other. Traffic streams of different VLANs are also isolated from each other. A smart VLAN can serve multiple users, thus saving VLAN resources. | The smart VLAN is used for xDSL access services, such as providing access to the Internet for the users in residential areas. |
MUX VLAN | A MUX VLAN contains only one service port and traffic streams of different VLANs are isolated from each other. One-to-one mapping can be set up between a MUX VLAN and an access user. Therefore, a MUX VLAN can uniquely identify an access user. | The MUX VLAN is used for xDSL access services, such as distinguishing users by VLANs. |
Super VLAN | A super VLAN is a VLAN based on layer 3. It consists of multiple sub VLANs. The ARP proxy is used for layer 3 interconnections among sub VLANs. A sub VLAN can be a smart VLAN or a MUX VLAN. | The super VLAN is used to save IP address resources and improve the usage efficiency of IP address resources. |
Thank you.
