Port-based
Example 1
Figure 17 illustrates an example of one AT-GS950/24 Gigabit Ethernet
Switch with three port-based VLANs. (For purposes of the following
examples, the Default VLAN is not shown.)
Figure 17. Port-based VLAN - Example 1
The table below lists the port assignments for the Sales, Engineering, and
Production VLANs on the switch.
Note the following about the example:
ˆ Each VLAN has a unique VID, which is assigned when you create the
VLANs.
ˆ Each port’s PVID value has been adjusted to equal the VID of its
respective VLAN. In order for a port to be considered an untagged
member of a VLAN, its PVID must equal the VID of the VLAN. This
must be performed manually.
