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.

IEEE -SA Standards Board Abstract: This standard specifies how the MAC Service is supported by Virtual Bridged Local Area Networks , the principles of operation of those networks , and the operation of VLAN -aware Bridges, including management, protocols, and algorithms.
Scope: This standard specifies Bridges that interconnect individual LANs, each supporting the IEEE 802 MAC Service using a different or identical media access control method, to provide Bridged Networks and VLANs .

Fundamentals of 802.1Q VLAN Tagging Last updated Oct 25, 2024 Save as PDF Table of contents Common Terms Best Practices Virtual local area networks , or VLANs , can be used to segment traffic within a network in combination with subnetting. VLANs keep traffic from different networks separated when traversing shared links and devices within a ...
A VLAN ( virtual LAN) abstracts the idea of the local area network (LAN) by providing data link connectivity for a subnet. VLANs make it easy for network administrators to partition a single switched network to match the functional and security requirements of their systems without having to run new cables or make major changes in their current network infrastructure. Each VLAN can be uniquely ...
IEEE 802.1
IEEE 802.1 802.1Q - Virtual LANs 802.1Q historically has been the standard specifying Virtual LANs and VLAN Bridges. It is intended to merge 802 .1D into 802.1Q , resulting in a combined bridging standard. The following historic versions of 802.1Q have pages on this site.
VLAN Tagging ( IEEE 802.1Q ): Inserts a 4-byte VLAN tag into Ethernet frames to identify the VLAN to which the frame belongs. VLAN Membership: Devices can be assigned to VLANs based on switch port, MAC address, or protocol type.
