Hello, I'm using the latest firmware (6.0) on my NWA1123-Acv2, and based on the ZYXEL-ES-WIRELESS.MIB attached, the OID to get the mac-address table of the devices connected should be 1.3.6.1.4.1.890.1.15.3.5.2.1.3.
This MIB doesn't look updated with the firmware revision (the "wlan station" table doesn't include the tcp address of the devices, which seams to be retrieved by the relevant SNMP call), and the info retrieved for MAC address look really weird and not corresponding to the expected values. How can I get this info out from my AP?
Thank you for your help.

    The last MIB file of the NWA1123-ACv2 is in below link for your reference.
    As the last MIB file, the MAC address of station is 1.3.6.1.4.1.890.1.15.3.5.2.1.2

    Zyxel_Freda,

    Thank you for your prompt reply...
    I tried this as well, without luck. This is what I get from the request with this OID:
    1.3.6.1.4.1.890.1.15.3.5.2.1.2

    .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.1 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.2 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.3 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.4 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.5 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.6 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.7 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.8 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.9 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.1.10 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.2.1 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.2.2 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.2.3 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.2.4 = Hex-STRING: 2A B9 FD F0 06 2D .1.3.6.1.4.1.890.1.15.3.5.2.1.2.2.5 = Hex-STRING: 2A B9 FD F0 06 2D

    While the number of entries (15) looks fine, the value of the Hex-STRINGs not. Do I miss something?

    We fixed this issue in a date firmware and would like to know that do you use the AP for standalone mode or managed by Nebula?
    We could help to upgrade the date firmware from backend if your devices are managed by Nebula after you provide the org/site name to us. Otherwise, we would provide the date firmware for you to upgrade on the standalone NWA1123-ACv2.
    Thanks.

    Hi @Zyxel_Freda,

    I'm using the AP in standalone mode. If you can provide me with the firmware, I'll do it by myself. Just let me know whether there's additional steps to follow other then the standard upgrade procedure.

    Thanks again for your prompt fix.

    Hi @Zyxel_Freda,

    Thank you for the new firmware, it's working much better with this SNMP command. However, I think, there's still an issue with mac addresses beginning with "00:", those are translated to empty values. I'm using the snmpwalk to test it, and below is what I get for these entries:

    snmpwalk -v 2c -c public -Ox 192.168.3.2 1.3.6.1.4.1.890.1.15.3.5.2.1.2

    ...
    SNMPv2-SMI::enterprises.890.1.15.3.5.2.1.2.1.9 = Hex-STRING: 50 4E 90 6D C9 D3
    SNMPv2-SMI::enterprises.890.1.15.3.5.2.1.2.1.10 ""
    SNMPv2-SMI::enterprises.890.1.15.3.5.2.1.2.1.11 ""
    SNMPv2-SMI::enterprises.890.1.15.3.5.2.1.2.1.9 = Hex-STRING: 08 44 92 8D C3 03
    ...

    and enabling the debug flag, the packet looks truncated:

    Received 51 byte packet from UDP: [192.168.3.2]:161->[0.0.0.0]:0
    0000: 30 31 02 01  01 04 06 70  75 62 6C 69  63 A2 24 02    01.....public?$.
