How does an AP go online

2

An AP goes online in the following modes:
1. Adding an AP offline and configuring AP attributes: AP attributes including the AP type and MAC address added to the whitelist are configured on the AC before the AP goes online. When the AP connects to an AC, the AC checks whether the AP can go online based on AP attributes. If the AP can go online, the AP can work based on the preconfigured attributes.
2. Discovering APs in the whitelist: The AP whitelist and AP authentication mode are configured on the AC. When an AP in the whitelist connects to the AC, the AC discovers the AP, and the AP works properly. The AP using the authentication mode configured on the AC exists in the whitelist and can go online.
3. Configuring AP discovery and confirming the AP identity: When an AP connects to an AC, the AC discovers the AP and prevents the AP from going online because the AP is not in the whitelist. The AP can go online only after its identity is confirmed by the user.

How to configure APs to go online statically or dynamically
Generally, if APs and the AC are on the same Layer 2 network, after the APs obtain IP addresses from the DHCP server, the APs can discover the AC by using broadcast and then connect to it. For configurations of APs to go online dynamically, see Example for Configuring APs to Dynamically Go Online in WLAN Typical Configuration Examples. If APs and the AC are not in the same network segment or users expect APs to go online dynamically on a specified AC, configure the IP address of the AC through the Option 43 field of the DHCP server. After obtaining the IP address through DHCP packets, the APs can go online on this AC according to the IP address carried by the Option 43 field. For the configurations, see Example for Configuring WLAN Services in Layer 3 Bypass Networking (Direct Forwarding) or Example for Configuring WLAN Services in Layer 3 Bypass Networking (Tunnel Forwarding) in WLAN Typical Configuration Examples. Users can also configure the IP address of the AC on the APs so that the APs can go online using the static IP address. For the configurations, see Example for Enabling an AP to Go Online Using a Static IP Address in WLAN Typical Configuration Examples.

An AP cannot go online. What is the troubleshooting roadmap
1. Check whether the number of APs exceeds the license specifications. 2. Check CAPWAP messages. 3. Check link information. 4. Check whether the configuration is delivered. 5. Check data flow information.

How to enable a WLAN AP to go online using a static IP address
To enable a WLAN AP to go online using a static IP address, perform the following configuration:
For V200R005 and V200R006, run the following commands on the AP:
system-view
[Huawei] ap-address mode static
[Huawei] ap-address static ip-address 192.168.10.2 24 192.168.10.1 //IP, mask, and gateway
[Huawei] ap-address static ac-list 192.168.10.1 //AC IP
[Huawei] quit
reboot
For V200R006, run the following commands on the AC:
system-view
[Huawei] wlan
[Huawei-wlan-view] provision-ap
[Huawei-wlan-provision-ap] ap-name XX
[Huawei-wlan-provision-ap] address-mode static
[Huawei-wlan-provision-ap] ac-list x.x.x.x
[Huawei-wlan-provision-ap] commit ap-name XX
