select the radio button for Port-Based VLAN to display the configuration options.
Figure 19. Port-Based VLAN page
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 indepen-
dent 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 for port-based VLANs (shown in
Figure
19) is that all of ports are connected so that all
ports can communicate with each other. Essentially, there are no virtual LANs. This option is the most flexible
but the least secure.
If you click the LAN1 to LAN4 only with line and Sniffing (as shown here),
there are port isolation means that each LAN's port can only communicate
with management port and cannot communicate with each other. This option
is the most limiting but also the most secure.
