Port-Based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
When using the port-based VLAN, the port is assigned to a specific VLAN independent of the
user or system attached to the port. This means all users attached to the port should be
members in the same VLAN. The network administrator typically performs the VLAN
assignment. The port configuration is static and cannot be automatically changed to another
VLAN without manual reconfiguration.
As with other VLAN approaches, the packets forwarded using this method do not leak into
other VLAN domains on the network. After a port has been assigned to a VLAN, the port
cannot send to or receive from devices in another VLAN.
The default setting is all ports connected which means all ports can communicate with each
other. That is, there are no virtual LANs. The option is the most flexible but the least secure.
