Hi all,

Recently I have upgraded my 4011 from 6.49.8 to software and firmware 7.11.2

On two of my 13 routers there was an unexpected behavior, after several ( one over 10, other over 14 ) days of work. Ethernet ports 1-5 went suddenly down.

In logs I only get : and then only logs about dhcp leases
Router is operational, I can log in on it, using connection on ether10 , but I can't bring ports 1-5 up. After a reboot everything is perfectly OK again.

Did you perhaps encounter similar behavior?

No, I haven't, with any version. Have you tried to reset your config since you upgraded ? If you did, maybe Netinstall. I am testing 7.12.1 presently. I will update you in a few weeks.

Maybe check if there are differences between those 13 configs that could explain this behaviour.

Have RB4011 as main router in our office. ROS 7.12.1 is running and i have no problems whatsoever.

Maybe if you can open support ticket with attached supout.rif file so support can check if something is wrong.

My client saw problems with ports 1-5 on two RB4011 switches in the past few weeks. First: OS 7.11.2, Boot 6.45.9 (factory). Second: OS 7.12, Boot 7.10.1 (factory). Both revision r2, firmware type al2. Model RB4011iGS+.

Ports 1-5 just quit working on both switches. I tried connecting locally with a laptop, no success. Neither DHCP or static IP was working. Ports 6-10 worked normally. After reboot the problem went away.

We will upgrade both switches to 7.13.2 in the hopes that it will solve this problem. I hope it's not hardware issue.

I am curious if 7.13.x fixes it. I just have had in the last 3 weeks two separate RB4011 routers running 7.12.1 do the same thing.

Both were new routers that were set to no configuration after upgrading from factory FW to 7.12.1. They were then configured manually.

Maybe an issue with the switch chip as ports 1-5 are on one switch chip and 6-10 on another.

I have opened a ticket with Mikrotik but I did not capture a support file before rebooting so I do not have that to send them.

If it continues I either need to switch them to an RB5009 (I have had one up for months with no issue) or downgrade them to ROS6 as I have an RB4011 on ROS6 that has been solid for years.

Of the two routers this happend to it is odd as one was installed on 9-29-23 and it was fine until the first port lockups on 2-16-24. The other router was installed on 1-26-24 and it just happend to it the first time today.

One similarity between both routers for me is that both have a Netonix switch connected to one of the first 5 ports doing router-on-a-stick setup with Vlans.

Do you have vlans or any similar setups on ports 1-5 on your routers that had this issue?

Watching this thread. I am still running 6.49.8 on my RB4011iGS+, but expecting to move to ROS 7 one of these days...

Would be good to have a look at your config:
Going from 6.x to 7.x is a big step. You might want to consider doing netinstall en config manually (or from an export) after.

Same problem happened to me yesterday, ports 1-5 were left as auto-negotiation failed.
