Example for Configuring Radio Calibration

Configuration Process

You need to configure and maintain WLAN features and functions in different profiles. These WLAN profiles include regulatory domain profile, radio profile, VAP profile, AP system profile, AP wired port profile, WIDS profile, WDS profile, and Mesh profile. When configuring WLAN services, you need to set related parameters in the WLAN profiles and bind the profiles to the AP group or APs. Then the configuration is automatically delivered to and takes effect on the APs. WLAN profiles can reference one another; therefore, you need to know the relationships among the profiles before configuring them. For details about the profile relationships and their basic configuration procedure, see WLAN Service Configuration Procedure.

Networking Requirements

As shown in Figure 1, a large number of APs are deployed in an office building. The APs connect to the AC through Switch_A to provide wireless services for users.

It will be a heavy workload to manually configure radio parameters (such as the channel) for the APs one by one. The enterprise IT department requires that the AC automatically allocate channels to the APs based on radio environments to simplify network deployment.

Figure 1 Networking diagram for configuring radio calibration

Configuration Roadmap

The configuration roadmap is as follows:

Configure the APs, AC, and upper-layer devices to communicate with each other.
Configure the AC as a DHCP server to assign IP addresses to the APs and STAs.
Configure a VLAN pool for service VLANs.
Configure the APs to go online.
1. Create an AP group and add APs that require the same configuration to the group for unified configuration.
2. Configure AC system parameters, including the country code and source interface used by the AC to communicate with the APs.
3. Configure the AP authentication mode and import the APs offline to allow the APs to go online.
Configure WLAN service parameters for STAs to access the WLAN.
Configure radio calibration so that the AC can automatically allocate the optimal working channels to the APs.

Configuration Notes

No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
- In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
- In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.
Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.

Procedure

Set the NAC mode to unified on the AC so that users can connect to the network properly.
```
<HUAWEI> system-view
[HUAWEI] authentication unified-mode
```
If the NAC mode is changed from traditional to unified, the unified mode takes effect after you save the configuration and restart the device.

Configure Switch_A and the AC so that the AP and AC can transmit CAPWAP packets.

Configure a VLAN pool for service VLANs.
# Create a VLAN pool, add VLAN 101 and VLAN 102 to the pool, and set the VLAN assignment algorithm to hash in the VLAN pool.

This example uses the VLAN assignment algorithm hash as an example. The default VLAN assignment algorithm is hash. If the default setting is not changed before, you do not need to run the assignment hash command.

In this example, only VLAN 101 and VLAN 102 are added to the VLAN pool. You can add multiple VLANs to a VLAN pool. Similar to adding VLAN 101 and VLAN 102 to a VLAN pool, you need to create corresponding VLANIF interfaces and configure IP addresses and interface address pools.

The default AP authentication mode is MAC address authentication. If the default settings are retained, you do not need to run the ap auth-mode mac-auth command.
