2. Check whether an AP has an IP address.

   Run the display ip pool { interface interface-pool-name | name ip-pool-name } used command to check allocated IP addresses. Check whether the AP has obtained an IP address based on the MAC address.

   [AC6605] display ip pool interface Vlanif1219 used

   Run the display ap unauthorized record command.

   <AC6605> display ap unauthorized record 

6. Check whether the MAC address or SN of the AP conflicts with that of another AP or is incorrectly set.

   Run the display wlan wdev ap-information ap-mac mac-address command in the diagnostic view to check the MAC address and SN of the AP.

   <AC6605> display wlan wdev ap-information ap-mac mac-address
