IEEE 802.1Q
IEEE 802.1Q IEEE 802.1Q , often referred to as Dot1q, is the networking standard that supports virtual local area networking ( VLANs ) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
IEEE 802.1Q is the networking standard that defines VLAN (Virtual Local Area Network) tagging on Ethernet frames. VLANs allow network administrators to segment a physical network into multiple logical networks, improving security, efficiency, and management.

The IEEE 802.1Q specification establishes a standard method for tagging Ethernet frames with VLAN membership information. It defines the operation of VLAN bridges that permit the definition, operation, and administration of VLAN topologies within a bridged LAN infrastructure.
VLAN Tagging (802.1Q) Master Guide
IEEE 802.1Q VLAN tagging is one of the most fundamental technologies used in enterprise networking. It enables logical segmentation of networks while allowing multiple VLANs to share the same physical infrastructure through trunk links. This master-level guide explains the VLAN tagging diagram from an enterprise architect perspective, including frame processing, packet tagging , switch behavior ...
Chapter 10. Configure 802.1Q VLAN tagging | Networking Guide | Red Hat Enterprise Linux | 7 | Red Hat Documentation Sending VLAN tagged packets through a network switch requires the switch to be properly configured. For example, ports on Cisco switches must be assigned to one VLAN or be configured as trunk ports to accept tagged packets from multiple VLANs . Some vendor switches allow untagged ...
