About VLANs

What is a VLAN?

A Virtual Local Area Network (VLAN) is a logical grouping of network devices that appear to be on the same LAN regardless of their physical location. VLANs segment network traffic, improve security, and reduce broadcast domains.

VLAN ID Range

VLAN IDs range from 1 to 4094. VLAN 1 is typically the default/native VLAN. VLANs 1002-1005 are reserved for Token Ring and FDDI. VLANs 1006-4094 are extended range VLANs (requires VTP transparent mode on some switches).

Best Practices

Use descriptive VLAN names
Document all VLANs and their purposes
Separate management traffic (VLAN 1 or dedicated)
Use consistent VLAN numbering across switches
Implement inter-VLAN routing with ACLs
