What is dot1q?

IEEE 802.1Q is a networking standard that defines VLAN (Virtual LAN) tagging. It adds a tag to Ethernet frames, specifying which VLAN they belong to. This allows a single physical network to be logically segmented into multiple VLANs, improving network security, performance, and manageability. It's commonly used in enterprise networks to isolate traffic between different departments or user groups.
