The feature that facilitates the tagging of frames on a specific VLAN is encapsulation.
In networking, VLANs (Virtual Local Area Networks) are used to logically partition a single physical network into multiple virtual networks. This helps to reduce network congestion, improve network security, and simplify network management. To ensure that frames sent on a VLAN are properly segregated from frames on other VLANs, the frames are tagged with a VLAN ID.
Encapsulation is the process of adding a header and trailer to a frame to carry additional information, such as VLAN IDs. The VLAN ID is added to the header of the frame in the form of a 4-byte VLAN tag, which contains a 12-bit VLAN ID, a 3-bit priority field, and a 1-bit flag field. This allows network devices to identify which VLAN a frame belongs to and process it accordingly.
Switching is the process of forwarding frames from one network device to another, and routing is the process of forwarding packets between different networks. Hairpinning is a term used to describe a scenario where a packet or frame is sent back out of the same interface it was received on. None of these features directly facilitate the tagging of frames on a specific VLAN.
