untaggedkehyksiä

untaggedkehyksiä is a Finnish term that translates to "untagged frames" in English. In the context of computer networking, specifically within Ethernet technology, untagged frames are standard data packets that do not carry any additional information about their network segment or Virtual Local Area Network (VLAN) membership. When a switch receives an untagged frame, it typically forwards it to all ports that belong to the same native VLAN as the ingress port.

This is in contrast to tagged frames, which are encapsulated with VLAN tags (IEEE 802.1Q). These tags allow network administrators to segment a physical network into multiple logical networks, improving security, performance, and manageability. Untagged frames, therefore, traverse the network without explicit VLAN identification and are associated with the default or native VLAN of the switch port they enter. Understanding the behavior of untagged frames is crucial for configuring VLANs correctly, especially when dealing with legacy devices or specific network topologies where explicit tagging is not applied.
