Configuring the PVID of Untagged Ports
This procedure adjusts a port’s VID value. The PVID value determines the
VLAN in which the port is an untagged member. A port is an untagged
member of the VLAN whose VID value matches its PVID. A port can be an
untagged member of only one VLAN at a time.
The ports of a new VLAN are initially designated as tagged ports. Their
PVID values retain their previous settings when they are assigned to a
new VLAN. If you want the ports to function as untagged members of a
new VLAN, you must change their PVID values to match the VID of the
VLAN, as explained in this procedure.
You can also use this procedure to change the VLAN assignment of an
untagged port. With this procedure you can move an untagged port from
one VLAN to another by changing its PVID value.
To adjust the PVID value of a port, perform the following procedure:
1. From the Advanced Config menu, select VLAN Config. > VLAN Port
Config.
The VLAN Port Configuration page opens, as shown in Figure 83.
Figure 83. PVID Page
2. Click the PVID field of the port whose value you want to change and
enter the new PVID value for the port. The PVID must be equal to the
VID of the VLAN where you want the port to be an untagged member.
For example, to make Port 10 an untagged member of a VLAN that
has a VID of 12, you would change its PVID to 12.
