The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This article aims to show you how to configure an interface VLAN on your Cisco Business 250 or 350 series switch to be an access, or trunk port.
Virtual Local Area Network (VLAN) is a group of ports that enables devices to communicate with each other over the Ethernet MAC layer, regardless of the physical Local Area Network (LAN). A port is a member of a VLAN if it can send to and receive data from the VLAN. A port is an untagged member of a VLAN if all packets destined for that port into the VLAN have no VLAN tag. A port is a tagged member of a VLAN if all packets destined for that port into the VLAN have a VLAN tag. VLANs are typically used to isolate endpoints as a workgroup. A basic example is setting up a different VLAN for Voice and a separate VLAN for Data. This ensures that packets for both data types are isolated from each other, maximizing the utilization of the switch.
You can assign an interface VLAN into a specific mode such as an Access or Trunk port.
Step 1. Log in to the web-based utility and choose VLAN Management > Interface Settings.
Step 2. In the Interface Settings Table, choose an interface from the Interface Type equals to drop-down list and then click Go. The options are:
In the example below, LAG is chosen.
Step 3. Click the radio button for the port or LAG you want to modify and click Edit.
A pop-up window will then appear showing the chosen interface type in the previous page.
Step 4. Choose the radio button that corresponds to the desired VLAN mode for the interface.
For this example, Trunk was chosen.
Step 5. Click Apply.
Step 6. The page will then show with a check mark that the settings have been successful. Click Close.
You will now be taken back to the Interface Settings Table.
Step 7. Check the interface mode that you have configured to verify your recent setting.
Step 8. To permanently save the current configuration, click on the blinking save icon.
You have now successfully assigned the interface VLAN on your Cisco Business 250 or 350 series switch.
