I just tried to replace my hAP ac with ac2 , by restoring on ac2 backup file that I created on ac.
Initially it all looked ok, ac2 got same IP ( and even same MACs on ports), I could connect via webfig, and it seemed like everything is where it should be.
But then I noticed problems:
- no internet via Ethernet1, and Mikrotik could not get address as DHCP client
- no internet even on backup interface (Ethernet3) - I could not ping 8.8.8.8 from desktop. BUT I could ping from router itself
To skip long story short, it turns out that one bridge filter rule that should have prevented LAN users via Ethernet2 from internet ( and allowed other LAN users to internet if coming from Ethernet4, like my desktop) did not work as intended - when I enable that rule, my PC from Ethernet4 was blocked, even if rule was for blocking Ethernet2.
Then I tried to switch cables, and it worked as intended ! Meaning ac2 has mislabeled/switched ethernet ports 2 and 4. Which gave me an idea that it maybe reversed all ports (except obviously port3), and that it may be reason for my default WAN (ethernet 1) not working, so I switched cables between ports 1 and 5 as well, and … internet on ‘Ethernet 1’ port got DHCL address and started working.
My hAP ac2 firmware/OS version was 6.44.5 , but when I upgraded to latest 6.46.2, problem remains same (ethernet ports are still reversed ).
Fact: restoring backup from hAP ac to ac2 resulted in reversed order of ethernet ports ( Ports 1,2,3,4,5 become 5,4,3,2,1 - so only #3 kept its number )
Question 1: is that normal (as in restoring backups from ac to ac2 is not supported, and anything can happen), or is it bug?
Question 2: is there some way in webfig ( or terminal) to see which ethernet/switch interface is connected to which physical ports (as labeled on box) ?
Question 3: is there some way to map ethernet interfaces to specific ethernet switch port? So I can move my interface named “Ethernet1-WAN” (which appears at many places in configuration) from current port5 to expected ethernet port1 ?
