VLAN Topology
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 102: Skywalker Enterprises.
- VLAN 400: Wireless.
- VLAN 401: Wide-Area Network.
- VLAN 402: ISDN/PSTN.
