AP205 Cannot boot on 7030 Controller

Hi, I am trying to reboot a AP-205 from 7030 Controller running ArubaOS 6.4.2.3. The AP-205 is keep showing Down state. I am not able to ping the AP-205.

 

Inspect the controller log we spot

Mar 14 15:08:15 stm[3538]: <305058> <WARN> |stm| AP DSG03AP08: Drop hello message from 10.8.2.21 with different MAC, old MAC 94:b4:0f:c1:7e:1a, new MAC 94:b4:0f:cb:2d:5c.

where the new MAC is the AP205 mac address while the old MAC is the MAC address belong to DSG03AP08.

 

The MAC 94:b4:0f:cb:2d:5c is belong to the AP-205 being boot.

 

Any insight to the problem? I have attached the controller log for your reference.

 

regards,

Wilson

Are you using static ip addresses or DHCP for your devices?

Hi Colin,

  We are using the DHCP for the devices.

  Seems that is problem also exists for AP-225. I have attached the bootlog for AP-225.

Re: AP205 Cannot boot on 7030 Controller

Is there a NAT boundary between your access points and your controller? (a router?)  The messages indicate that two devices are sharing the same source port, like if they are behind a NAT device.

The device is on the same vlan as the controller. There is no nat in this
segment. Purely layer 2.

Re: AP205 Cannot boot on 7030 Controller

Colin,

   The issue seems to be ip conflict issue. The microsoft DHCP Server in our network reboot without notice. An AP reboot and request IP and server DHCP assigned an IP without knowing that it has been assigned prior to the reboot. As a result, AP boot failed. We need to reboot all the AP in our network.

   I am just wonder if there are any recommendations from Aruba to prevent this siutation from happening again. Anyway that we can prevent AP reboot after the DHCP restart?

 

Regards,

Wilson

Seaman,

 

Unfortunately, there is no built-in protection for this.  The Aruba access point depends on getting a valid ip address from your infrastructure.  If it does not get an ip address, as you see, it cannot function.
