VLAN Topology

In order to allow our network to be scalable, we have allocated VLAN ranges to specific areas. Please note that even though we only use a range of 1000 VLANs, newer switches allow for more than 4000.

Predefined VLAN assocations

While only a few of these VLANs are actually in use, the VLAN ranges will allow our network to scale almost indefinitely.

  • 1: Not in use; clear from all trunks. This is a Cisco best practice implementation (not required).
  • 2-99: Management VLAN on all switches.
  • 100–399: Access layer devices.
  • 400–599: Data center devices.
  • 600–699: Internet and partner connections.
  • 700–899: Reserved for future use.
  • 900–999: Point-to-point links between switches (Layer 3).

VLANs currently in use

  • VLAN 45: Management VLAN used on all switches in the network.
  • VLAN 100: Skywalker Enterprises.
  • VLAN 400: Wireless.
  • VLAN 401: Wide-Area Network.
  • VLAN 402: ISDN/PSTN.
