Configuring AP Indicators
Context
Different states of AP indicators reflect different meanings, thereby facilitating installation and management. Configuring meanings reflected by blinking of the Wireless indicator on APs helps installation personnel to know the current signal strength or traffic status in real time. However, blinking indicators of indoor APs deployed in hospitals and hotels may affect people's nighttime rest. Therefore, you can turn off AP indicators after APs are installed and run properly.

- Run radio-2g-profile name profile-name or radio-5g-profile name profile-name
A 2G or 5G radio profile is created and the radio profile view is displayed.
By default, the system provides the 2G radio profile default and 5G radio profile default.
- Run wifi-light { signal-strength | traffic }
The information reflected by the blinking frequency of the Wireless indicator on an AP is configured.
By default,- If WDS
is enabled on an AP, the blinking frequency of the Wireless LED reflects
the strength of signals received from a WDS AP.
- If the AP works in leaf mode, the blinking frequency of the Wireless LED reflects the strength of signals received from a middle AP.
- If the AP works in middle mode, the blinking frequency of the Wireless LED reflects the strength of signals received from a root AP.
- If the AP works in root mode, the blinking frequency of the Wireless LED reflects the weakest signal strength of middle APs.
- If the WDS functions are disabled on an AP, the blinking frequency of the Wireless LED reflects the service traffic volume on the radio.
On a WDS network, you need to adjust AP locations and antenna directions to obtain strong signals between WDS-capable APs. The blinking frequency of the Wireless LED shows the signal strength.
This command takes effect only when the AP has the WDS function enabled. If the WDS functions are disabled on the AP, the Wireless LED always shows service traffic volume.
Only APs having Wireless LEDs support this command.

Configuring a Management VLAN on an AP
Context
Generally, the PVID of the access device interface to which an AP directly connects is configured as the management VLAN ID. For details, see Configuration Precautions for Basic WLAN Services. Management packets sent by the AP are then transmitted on CAPWAP tunnels. When the packets arrive at the access device, the access device adds the PVID to the packets as their VLAN tags. If the PVID of the access device has been used as the default VLAN tag of wired users, the PVID cannot be configured as the management VLAN ID on the access device interface. In this case, configure a management VLAN on the AP. The AP then encapsulates the control packets sent to the AC in CAPWAP packets and adds the management VLAN ID to the packets as their VLAN tags. You only need to configure the access device to allow only the packets carrying the management VLAN ID to pass.

Configuring the Alarm Function on an AP
Context
You can configure alarm thresholds on an AP to monitor the AP in real time. When the configured thresholds are exceeded, the AP generates alarms or logs to notify the AC of AP status.
The default alarm thresholds are recommended.
If a STA cannot go online due to security type mismatch, UAC, or access user upper limit exceeding, the STA will automatically re-connect to the AP. During this period, the AP sends a large number of STA association failure alarms to the AC, which degrades the system performance.
To solve this problem, enable alarm suppression for the AP. The AP then does not report alarms repeatedly in the alarm suppression period, preventing alarm storms.
Procedure

Configuring the Log Backup and Log Suppression Functions on an AP
Context
Logs record user operations and system running information. After logs are backed up to a server, network administrators can summarize and analyze AP logs to learn about the operations performed on APs for fault location.
The device supports automatic log backup. After automatic log backup is configured, logs generated by an AP are automatically sent to the log server.
If a STA keeps attempting to connect to an AP because of signal interference or instability, the AP sends a large number of duplicate login and logoff logs to the AC in a short period, causing a huge waste of resources.
To address this problem, enable log suppression. The AP sends only one log about a user to the AC within the log suppression period.
Procedure
- Run system-view
The system view is displayed.

Configuring LLDP on an AP
Context
The Link Layer Discovery Protocol (LLDP) helps the NMS obtain detailed Layer 2 information, such as the network topology, device interface status, and management address.
After LLDP is configured on an AP, the AP can send LLDP packets carrying local system status information to directly connected neighbors and parse LLDP packets received from neighbors. After the AP discovers a neighbor, the AP sends neighbor information to the AC. The NMS then obtains AP's LLDP information from the AC to learn about the network topology.
To enable an AP to discover neighbors, enable LLDP on the AP and access device to which the AP directly connects.
Procedure

The system view is displayed.
- Run wlan ac

Configuring Service Holding upon CAPWAP Link Disconnection
Context
To mitigate impact of link disconnections on users in direct forwarding mode and improve service reliability, you can configure the function of service holding upon CAPWAP link disconnection. After the disconnected CAPWAP link is restored, the AP forces all online STAs to go offline and reassociate with the AP and reports information about the STAs through logs.
Service holding upon CAPWAP link disconnection is only applicable to the direct forwarding mode.
WDS networks do not support service holding upon CAPWAP link disconnection.
Procedure
- Run system-view
The system view is displayed.
- Run wlan ac
The WLAN view is displayed.
- Run ap-system-profile name profile-name
An AP system profile is created, and the AP system profile view is displayed.
By default, the system provides the AP system profile default.

Optimizing AP System Profile Parameters
Context
This task is to configure an AP to directly respond to association requests of STAs and configure the MTU of Ethernet port in the AP system profile and the Extensible Authentication Protocol (EAP) packet conversion function.
Procedure
- Run system-view
The system view is displayed.
- Run wlan ac
The WLAN view is displayed.
- Run ap-system-profile name profile-name
An AP system profile is created, and the AP system profile view is displayed.
By default, the system provides the AP system profile default.
- Run mtu mtu-value
The MTU of Ethernet ports is configured in an AP system profile.
The default the MTU of Ethernet ports in an AP system profile is 1500 bytes.
The size of data packets is limited at the network layer. When a network layer device receives an IP packet, it determines the outbound interface and obtains the MTU configured on the interface. The device then compares the MTU with the IP packet length. If the IP packet length is longer than the MTU, the device fragments the IP packet. Each fragment has the smaller or equal size as the MTU.
If the MTU value is smaller than the DHCP packet length, the AP may be disconnected. In this case, restart the AP.
- Configure EAP packet conversion.
Different vendors use different methods to encapsulate EAP packets in broadcast, multicast, or unicast packets. In 802.1X authentication, when an AP sends EAPOL-Start and EAPOL-Response packets to an AC, the method that the AP uses to encapsulate the two types of packets must be the same as the method that the access device directly connected to the AC uses. Otherwise, the two types of packets cannot be processed by the access device directly connected to the AP. Consequently, the user cannot pass 802.1X authentication.
