Summary VLANS
Allows an administrator to logically group devices that act as their own network
Are used to segment broadcast domains
Some benefits of VLANs include
Cost reduction, security, higher performance, better management

Summary
Types of Traffic on a VLAN includeData
Voice
Network protocol
Network management
Communication between different VLANs requires the use of
Routers

Summary
Trunks
A common conduit used by multiple VLANS for intra-VLAN communication
EEE 802.1Q
The standard trunking protocol
Uses frame tagging to identify the VLAN to which a frame belongs
Does not tag native VLAN traffic
