VLANs

Overview
  • Shouldn’t have more than 3-4 VLANs
  • Not needed for smaller networks
  • Isolates broadcast domains
  • Enhance security controls (Guest wi-fi)
Ports
  • ‘Trunk’ port carries multiple VLANs (i.e. uplink ports, WAPs with guest network)
  • ‘Access’ port only carries one VLAN (i.e. isolate POS equipment)
Note:
  • Match VLAN number to subnet (third octet)
