On the AP label sticker, only one MAC address is provided. So, how can one determine the MAC addresses for the LAN port and VAP?

Let's consider a general example:

Suppose the AP hardware MAC address is AA:AA:AA:AA:AA:AA and it has 2 LAN ports.

For LAN ports:

  • The MAC for LAN1 port would be AA:AA:AA:AA:AA:AB
  • The MAC for LAN2 port would be AA:AA:AA:AA:AA:AC

For the VAPs:

  • The MAC for VAP1 (radio 1 - 2.4GHz, wlan-1-1) is AA:AA:AA:AA:AA:AD
  • The MAC for VAP2 (radio 2 - 5GHz, wlan-1-2) is AA:AA:AA:AA:AA:AE

Suppose the AP hardware MAC address is AA:AA:AA:AA:AA:AA and it has no LAN ports.

For the VAPs:

  • The MAC for VAP1 would be AA:AA:AA:AA:AA:AB
  • The MAC for VAP2 would be AA:AA:AA:AA:AA:AC

This follows the rule base on the hardware MAC address and in the hexadecimal system:

  • If there are LAN ports, each subsequent port's MAC address increments by 1. After the LAN ports, the VAP MAC addresses follow.
  • If there are no LAN ports, the VAP1 MAC address increments by 1, followed by VAP2, and so on.

Additionally:

  • VAP1 also is BSSID for the first SSID of radio1 2.4GHz and VAP2 is the BSSID for the first SSID of radio2 5GHz.

For instance:

  • For the WAC500H model, there are 2 LAN ports.

For the NWA55AXE model, there are no LAN ports.
