Step 3: Configure VLAN for untagged devices
Even if the device attached to the switch doesn’t support 802.1Q tags it is
still possible for the device to participate in the VLAN. When
communicating with untagged devices the switch:
Determines how to forward untagged traffic. For untagged traffic, the
switch assigns a default VID to the incoming traffic from the untagged
device. Normally, all untagged traffic received on the switch is assigned a
VLAN ID=1 or the DEFAULT_VLAN. You can change this PVID to the VID
of the VLAN you want the port to use.
Strips 802.1Q tags before sending traffic to the untagged device. When the
switch needs to send traffic from a port to an untagged device, it strips the
802.1Q tag. Otherwise the untagged device may not understand how to
process the VID tag.
To add an untagged device to an 802.1Q VLAN
1Ensure that the port is a member of the VLAN. Follow the procedure in
step 1, “Create an 802.1Q VLAN and add ports,” to add a port to an
802.1Q VLAN.
2On the Configure VLAN menu, select Configure VLAN ID for untagged
and priority-tagged traffic and press E.
3Select the port where the untagged device is connected. For example,
port 7.
4Type the VID of the VLAN you want the port to belong to and press
E. This is the same ID number you entered in step 1.
5Select APPLY and press E to activate the changes.
By specifying a VID you set the switch to assign a particular VID to any
incoming traffic it receives on that port.
