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).
