Every few months we had to disable the wired network in order to prevent non-employees from being able to get online. This was not scalable, was prone to human error, and scheduling confusion. I planned to automate the process by enabling 802.1X aka dot1q on the switches using our Windows AD via Cisco ACS.

Long term I planned to enable a wired guest VLAN and had it labbed out for non local switched wifi where the guest VLAN exists on the switch you’re connected to but didn’t around to labbing local switching using CAPWAP tunnels.
Wired Guest Access using Cisco WLAN Controllers Configuration Example:
Phones would … Continue reading...
