ROS assigning the same MAC address to two SSID

RouterOS Wireless Networking

I’m using Winbox to setup virtual Wifi Access Points on HapAcLite, ROS 6.49.8.

I noticed that ROS is assigning the same mac-address (4A:8F:5A:0B:B6:D8) to ssid=zz5_i and zz5_m as show below. Is this normal and will this work OK? Thanks.

/interface wireless

set [ find default-name=wlan2 ] disabled=no mode=ap-bridge name="WifiLAN5G[TRUSTED]" security-profile=\
    "WifiSecProfile[TRUSTED]" ssid=zz5_t

add disabled=no keepalive-frames=disabled mac-address=4A:8F:5A:0B:B6:D8 master-interface="WifiLAN5G[TRUSTED]" \
    multicast-buffering=disabled name="WifiLAN5G[IOT]" security-profile="WifiSecProfile[IOT]" ssid=zz5_i vlan-id=20 \
    wds-cost-range=0 wds-default-cost=0 wps-mode=disabled

add disabled=no keepalive-frames=disabled mac-address=4A:8F:5A:0B:B6:DB master-interface="WifiLAN5G[TRUSTED]" \
    multicast-buffering=disabled name="WifiLAN5G[MEDIA]" security-profile="WifiSecProfile[MEDIA]" ssid=zz5_m vlan-id=30 \

add disabled=no keepalive-frames=disabled mac-address=4A:8F:5A:0B:B6:DD master-interface="WifiLAN5G[TRUSTED]" \
    multicast-buffering=disabled name="WifiLAN5G[WORK]" security-profile="WifiSecProfile[WORK]" ssid=zz5_w vlan-id=40 \
    wds-cost-range=0 wds-default-cost=0 wps-mode=disabled

I don’t see duplicate mac addresses on the other virtual access points that I’ve setup:

set [ find default-name=wlan1 ] band=2ghz-g/n disabled=no installation=indoor mode=ap-bridge name="WifiLAN2G[TRUSTED]" \
    security-profile="WifiSecProfile[TRUSTED]" ssid=zz2_t

add disabled=no keepalive-frames=disabled mac-address=4A:8F:5A:0B:B6:D9 master-interface="WifiLAN2G[TRUSTED]" \
    multicast-buffering=disabled name="WifiLAN2G[IOT]" security-profile="WifiSecProfile[IOT]" ssid=zz2_i vlan-id=20 \
    wds-cost-range=0 wds-default-cost=0 wps-mode=disabled

add disabled=no keepalive-frames=disabled mac-address=4A:8F:5A:0B:B6:DA master-interface="WifiLAN2G[TRUSTED]" \
    multicast-buffering=disabled name="WifiLAN2G[MEDIA]" security-profile="WifiSecProfile[MEDIA]" ssid=zz2_m vlan-id=30 \
    wds-cost-range=0 wds-default-cost=0 wps-mode=disabled

add disabled=no keepalive-frames=disabled mac-address=4A:8F:5A:0B:B6:DC master-interface="WifiLAN2G[TRUSTED]" \
    multicast-buffering=disabled name="WifiLAN2G[WORK]" security-profile="WifiSecProfile[WORK]" ssid=zz2_w vlan-id=40 \
    wds-cost-range=0 wds-default-cost=0 wps-mode=disabled

No, running CAPs with same MAC address won’t work, clients will get pretty confused (it’s actually used as BSSID and it needs to be unique in the neighbourhood). So do change it on one of VAP interfaces. Just make sure it’s different than anything else in your network. Or delete the VAP interface and create it again, perhaps this time the UI of choice will make better decission.

Thank you mkx, I deleted everything and started over and ROS gave me all unique mac addresses this time. Weird. Glad I checked it though. :smiley:

EDIT: MY BAD! Upon looking at this further ROS was giving unique mac addressed the first time in my OP- 4A:8F:5A:0B:B6:D8 and 4A:8F:5A:0B:B6:DB. The last digits are 8 and B which look very similar but are indeed different! :open_mouth: :open_mouth: :smiley: :laughing:
