Is the MAC address of an SSID broadcast by a Huawei AP the same as the AP's MAC address

The MAC address of an SSID broadcast by a Huawei AP is automatically generated based on parameters such as the carrier ID and AP ID, which ensures that the uniqueness of the MAC address. Therefore, the MAC address is different from that of the AP.

MAC address calculation rule:

The basic service set identifier (BSSID) is used to uniquely identify an AP and the BSSID format is the same as that of the MAC address, that is, XXXX-XXXX-XXXX. If an AP has only one SSID, the BSSID is the AP's MAC address.

A Huawei AP supports multiple VAPs, each of which has a unique BSSID. If the BSSID of each VAP uses the AP's MAC address, duplicate BSSIDs exist. An algorithm is adopted to ensure that the BSSID of each VAP is unique and associated with the AP's MAC address.

The following takes a dual-band AP's MAC address dcd2-fc01-1b40 as an example. Generally, each frequency band supports 16 VAPs. The algorithm of VAPs' BSSIDs is as follows:

1. On radio 0, the BSSID of the first VAP is the AP's MAC address. The BSSIDs of the subsequent VAPs are incremented by 1 on the previous BSSIDs.

2. On radio 1, the BSSID of the first VAP is obtained by adding 1 to the last but one bit of the AP's MAC address. The BSSIDs of the subsequent VAPs are incremented by 1 on the previous BSSIDs. For example, if the AP's MAC address is dcd2-fc01-1b40, the BSSID of the first VAP on radio 1 is dcd2-fc01-1b50.

3. On radio 2, the BSSID of the first VAP is obtained by adding 2 to the last but one bit of the AP's MAC address. The BSSIDs of the subsequent VAPs are incremented by 2 on the previous BSSIDs. For example, if the AP's MAC address is dcd2-fc01-1b40, the BSSID of the first VAP on radio 2 is dcd2-fc01-1b60.
