VLAN

Description
VLAN This unit covers Virtual Local Area Networks (VLANs) which allow us to segment a large network. The broadcasts go to the same VLAN and are composed of two major port types:
  • Access Ports: allow us to connect devices in one particular VLAN to a switch
  • Trunk Ports: allows us to connect different switches to multiple VLANS
VLANS filter with different criteria depending on how they’re configured:
  • Physical Port
  • MAC Addresses
  • Sub netting IP Addresses
VLANs are very useful in that they help to segment large networks, cut down on traffic on make networks a bit more secure.
