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.

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.
Access port — A port that carries traffic only to and from the specific VLAN assigned to it.
Trunk port — A port that is capable of carrying traffic for any or all the VLANs that are accessible by a specific switch.
This article aims to show you how to configure an interface VLAN on your switch to be an access, or trunk port.
