關於Mobility Express轉LAP注意事項

在實際的網絡環境中，有些時候我們需要將ME模式的AP轉換為LAP工作。

PS：ME模式是思科8系列的AP可以支持，例如AP1852、AP2802、AP3802等型號。它可以作為控制器使用，同時也可以工作在LAP模式。

我們可以不通過轉換AP的鏡像來使得AP工作在CAPWAP，需要輸入LAP模式下輸入ap-type capwap，此時AP會重啟（修改AP的模式都會使得AP重啟）

具體操作：

To convert a Mobility Express AP into a CAPWAP AP, you must change its ap-type from mobility-express to capwap, though the CLI, as given in this procedure:

1. Connect to the Console Port, Telnet or SSH to the AP. <<<<注意這里，雖然提到可以通過Telnet / SSH，但是實際只能console，且遠程方式只支持SSH
2. Login to the Mobility Express controller console.
3. In the Mobility Express controller console, use the command apciscoshell to connect to the AP console.
4. Login to the AP console using the username Cisco and password Cisco. Both are case-sensitive.
5. Enter enable.
6. Enter the command ap-type capwap, and confirm .

Once the AP type is CAPWAP, the AP will not start its Mobility Express controller functionality and does not participate in the Mobility Express master AP election process. This AP can then be deployed in a physical wireless controller-based network (i.e. in a non-Mobility Express network). There the AP will join that controller, and as the image on the controller will be different, the AP will request a CAPWAP image from the controller, reboot, and rejoin the controller as a CAPWAP AP.

To convert multiple access points running Mobility Express image to CAPWAP simultaneously from the Mobility Express controller CLI, execute the following command:

(Cisco Controller) > config ap unifiedmode <switch_name> <switch_ip_address>

The arguments <switch_name> and <switch_ip_address> are the name and IP address, respectively, of the WLC to which the APs need to be migrated to.

The above command converts all APs to AP Configuration: NOT MOBILITY EXPRESS CAPABLE. The APs are then reloaded, and they come back up in local mode.

上述1中涉及到的現象：只能通過console

(Cisco Controller) >apciscoshell  <<<<<提示信息如下

apciscoshell CLI is not supported from Telnet or SSH Session. It is only supported from Console.

所以，如果通過登錄ME的CLI界面輸入ap-type命令來修改，需要通過console。但是如果你可以遠程接入該ME AP的LAP模式的下，可以在該模式下去修改ap-type capwap,此時AP會重啟，然后嘗試加入WLC。

同理，如果是鏡像轉換，也需要登錄到LAP模式下#模式輸入：

#ap-type mobility-express tftp://<tftp server ip-address>/<filename with path from root>
