- 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 include
Data
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
