Hello! I have RB1100AHx4 (R1) and hAP (SW2) connected with trunk.
Ping from R1 to SW2 works, but vise versa no.
Please help me understand the reason. I suppose it`s because of this message in log:
interface,warning vlan80--SI--trunk-to-SW2-sysadmins: bridge port received packet with own address as source address (b8:69:f4:15:15:92), probably loop
R1 /interface print

UPD: I found information about auto-mac for bridges and with admin-mac I`ve changed it. But the problem is still there. And as I can see mac addresses of vlan interfaces are equal too. Should I change all of them manually?
UPD2: I’ve found roots of ping problem in firewall. So, its ok now. But the error continues repeating in log on R1. From [that article](https://wiki.mikrotik.com/wiki/Change_MAC_address_of_VLAN_interface) I understand one cant change mac on VLAN interface, so I changed macs on all bridges on R1. No use.
R1 /interface print now
