Virtual LAN’s • VLAN – collection of nodes grouped together in a single broadcast domainbased on something other than physical location • LAN bridge • Filtering databases • IEEE 802.1Q Draft Standard
History of VLAN • Developed by Dr. W. David Sincoskie (1984) • Addressed the problem of scaling up Ethernet • Invented VLANs by adding a tag to • each Ethernet packet • By sending a mix of different packets, • bandwidth could be improved • 802.1Q header, or VLAN tag
Why use VLANs? • VLANs have several advantages • Performance • Formation of Virtual Workgroups • Simplified Administration • Reduced Cost • Security
Setup • How to set it up: • Single physical broadcast domain and chop it up • Require special switches.
1 Switch = 2 VLANs • “VLAN” plus a # • Ex. VLAN1 or VLAN2 • Switch with 2 VLANs • Multiple ways to support VLANs • Assign ports to a VLAN • Assign MAC addresses to determine VLAN membership
Configuring a VLAN-Capable Switch • Access the switch with a Web browser interface.
Configuring a VLAN-Capable Switch • Define VLANs
Configuring a VLAN-Capable Switch • Assign computers’ MAC addresses to VLANs or assign ports to VLANs
Trunking • Transferring VLAN traffic between two or more switches • A port on each switch must be configured as a trunk port. • Trunk Port
Virtual Trunk Protocol • Used to automate the updating of multiple VLAN switches • 3 Stages • Server • Client • Transparent • All the connected client switches update their configurations within minutes
InterVLAN Routing • Process of making a router work between two VLANS is interVLAN routing. • Each VLAN becomes its own broadcast domain. • No way for data to get from one VLAN to another unless you use a router
