ether2 - is master port for ether3,4,5.
ether2 is NOT connected.
When i connect link to ether3, 4 or 5, ether2 is upping to 10M, half duplex.

04:06:26 interface,info ether3 link down
04:06:27 interface,info ether2 link down
04:06:28 interface,info ether3 link up (speed 100M, full duplex)

04:08:25 interface,info ether4 link up (speed 100M, full duplex)

04:11:32 interface,info ether5 link up (speed 100M, full duplex)

The network cables are not broken?
Which devices are associated with it?

But it is not clear. It is not clear visualy on the led there is a link at the port or not.

Connect a network cable on the questtionable interface.
Connect the network cable to a computer.
Ping from the computer to an IP-adres on the router.
Are there interruptions?
So not, maby a bug in RouterOs

Connect a network cable on the questtionable interface.

PING ok, all work ok.
But IMHO it is incorrect, when cable is not conneted and link on port is up.
If it is a bug, how i can ask this to Mikrotik support?

Hello,

The lit port LED is a cosmetic issue on a Fast Ethernet switch chip due to
“Running” state of the master-port when a link of its slave-port turns on.

It is planned to address this master-port LED imperfection along with other switch
chip changes in RouterOS v7.

Regards,

Thx for all.
Haven’t questions anymore.

Hello! Check ethernet port on PC or Notebook. One non-working port on a computer or laptop can cause all ports on the router to reboot. A non-working port can be checked by an exception method.
