As mobile office and wireless network access gain more popularity the ports that terminal devices use to access the networks are very often non fixed A device may access a network through Port A this time but through Port B the next time If Port A and Port B belong to different VLANs the device will be assigned to a different VLAN the next time it accesses the network As a result it will not be able to use the resources in the old VLAN On the other hand if Port A and Port B belong to the same VLAN after terminal devices access the network through Port B they will have access to the same resources as those accessing the network through Port A do which brings security issues MAC based VLAN technology provides user access and ensures data security MAC based VLANs group VLAN members by MAC address With MAC based VLAN configured the device adds a VLAN tag to an untagged frame according to its source MAC address MACbased VLANs are mostly used with security technologies such as 802 1X to provide secure flexible network access for terminal devices Configuration The MAC based VLAN entries can be configured here This page allows for adding and deleting MACbased VLAN entries and assigning the entries to different ports This page shows only static entries Web Interface To configure MAC address based VLAN configuration in the Web interface 1 Click MAC address based VLAN configuration and add new entry 2 Specify the MAC address an
