NOTE

Determine which devices on your network support tag-based VLANs and which do not before you start this procedure.

Step 3: Configure VLAN for untagged devices

Even if the device attached to the switch doesn’t support 802.1Q tags it can 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 a untagged device to a 802.1Q VLAN

1Ensure that the port is a member of the VLAN. Refer to the procedure in step 1, “Create an 802.1Q VLAN and add ports,” to add a port to a 802.1Q VLAN.

2On the Configure VLAN menu, select Configure VLAN ID for Untagged Devices 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, “Create an 802.1Q VLAN and add ports.”

5Select APPLY and press Eto 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.
