Network Configured To Automate Cisco APs

We had a couple Cisco APs go bad on us recently. I bought a couple replacements and soon realized that my laptop doesn’t have a COM port… No consoling in to set IP config on the APs. After a little research, I decided to set up out network (DHCP, DNS) to auto-config new APs. Short version below:

Configured network infrastructure to support Cisco Aironet c1300 series APs.

  • Created DNS entry in domain: CISCO-LWAPP-CONTROLLER.myDomain.com –> <IP of WLC>
  • In DHCP Scope
  • Added Scope Option: 43 = <calculated HEX value>
    • See: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00808714fe.shtml#t1
    • See: http://www.cisco.com/en/US/docs/wireless/access_point/1130/installation/guide/1130hig_book.pdf
  • Reset APs to factory defaults: held down reset button while plugging power in.
  • Plugged AP into network.
  • Once WLC sees and updates the AP:
    • Rename AP
    • Enable HREAP (as needed)
    • Change AP Group as needed
    • Verify all settings
