Virtual LANs
VLANs segment a single flat L2 broadcast domain into multiple logical L2 networks. Each VLAN is uniquely identified by a VLAN ID or tag
consisting of 12 bits in the Ethernet frame. VLAN IDs range from 1 to 4093 and provide a total of 4093 logical networks.
You can assign ports on a single physical device to one or more VLANs creating multiple logical instances on a single physical device. The
virtual logical switches spanning across different physical devices emulate multiple logically segmented L2 networks on a single physical
network.
Each VLAN has its own broadcast domain. The unicast, multicast, and broadcast network traffic from ports that belong to a VLAN
forwards or floods to ports in the same VLAN only. Traffic between VLANs routes from one VLAN to another. You can also assign each
VLAN an IP address to group all the ports within a single IP subnet.
