Cisco AireSpace stuff that's been around forever and I think is finally being moved into IOS. I haven't used the IOS version, just the old WLCs that are going EOL soon. Meraki wireless will be under Meraki.

DHCP Options to point to WLC:

• Option 43 (LWAPP, older version)
  • Wireless Controllers Option 43 Generator
  • Search for Cisco Option 43 Calculator
  • Python script
• Option 82
