Port-Based
VLANs
Port-based VLANs are logical groupings of ports. Any devices connected
to the member ports share a common broadcast domain. The traffic
within a VLAN is forwarded only to the member ports.
As a frame enters a port, an ID for that port VLAN is associated with the
frame. This VLAN ID (VID) is used to forward the frame only to the port
or ports in the same VLAN (i.e., ports having the same VID).
When you create a new VLAN and give the VLAN a VID, each member
port Port VLAN ID (PVID) is set equal to the VID of the given VLAN
group through the Port to VLAN Configuration menu.
Port-based VLANs belong to separate broadcast domains; therefore, a
router is required to transfer the frames among the various VLANs.
Port-based VLAN Example
Figure 42 is an example of two port-based VLANs in an AT-9006SX/SC
switch. The example illustrates the two VLANs Sales and Production.
