4.17.1. MAC-based VLAN
MAC address-based VLAN decides the VLAN for forwarding an untagged frame based on
the source MAC address of the frame.
A most common way of grouping VLAN members is by port, hence the name port-based
VLAN. Typically, the device adds the same VLAN tag to untagged packets that are
received through the same port. Later on, these packets can be forwarded in the same
VLAN. Port-based VLAN is easy to configure, and applies to networks where the locations
of terminal devices are relatively fixed. 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. To provide user access and ensure data security in the meantime, the
MAC-based VLAN technology is developed.
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. MAC-based VLANs are mostly used in conjunction with security technologies
such as 802.1X to provide secure, flexible network access for terminal devices.
