WHAT IS VLAN?
A virtual local area network (VLAN) is a network on which users are enabled to share a more visual sense of community through high band-width connections.

ROUTER

MAIN GOALS
connectivity
security
management

VLAN TECHNIQUES
Two techniques:
Frame Filtering --examines particular information about each frame (MAC address or layer 3 protocol type)
Frame Tagging --places a unique identifier in the header of each frame as it is forwarded throughout the network backbone.

VLAN CONFIGURATIONS

STATIC VLANS
Static membership VLANs calls port-based and port-centric

DYNAMIC VLANS
Dynamic VLANs allow for membership based on MAC address to the device connected to the switch port.
This VLANs are created through network management software
