TitleHow to disable fabric attach on ERS so it does not automatically provision WiNG APs?
Objective
WiNG APs are getting configuration changes after reboot while connected to ERS? Disable fabric attach!
Environment
  • ERS 5000 Series
  • ERS 8000 Series
  • ERS 3000 Series
  • ERS 4000 Series
  • WING/Summit WM
  • ERS 2000 Series
  • Fabric Solutions
Procedure
If you have issues configuring a WiNG AP, make sure it is not configured by Fabric Attach enabled switch.

You will see this in device logs (show logging) seeing below message 
 
#show logging <on 7532> | include SYSTEM-6-CONFIG_COMMIT

Nov 01 14:20:30 2018: 7532 : %SYSTEM-6-CONFIG_COMMIT: Configuration commit by user 'cfgd' (update fabric attach) from '127.0.0.1'

If you see above message, connect to affected ERS and disable FA eihter in general or per-port
 
# configure terminal
(config)# no fa port-enable

or

(config)# interace ethernet 1/X
(config-interface-1-X)# no fa port-enable

Most probably you will have to provide additional configuration to provision correct switchport configuration on ERS
For more details find Configuring Systems on Ethernet Routing Switch 3600 Series
 
Additional notes
Be careful to check AP configuration prior you disable FA on ERS
If FA config is provisioned WiNG device will use following setup
 
interface ge1
  switchport mode trunk
  switchport trunk allowed vlan X
  switchport trunk native vlan X
  switchport trunk native tagged
