Explanation

IEEE 802.1Q is a standard for VLAN tagging in Ethernet networks. In Cisco IOS, VLANs are typically assigned to Layer 2 subinterfaces, which are logical interfaces that allow a physical interface to be divided into multiple virtual interfaces. Each Layer 2 subinterface can be assigned a unique VLAN ID, allowing traffic to be separated and managed based on VLAN membership.
