All Ethernet Interfaces show 'R' -running no matter what

Fri Oct 15, 2010 12:56 am

I was hoping that the new releases of v5 would solve a problem I have with virtually all my x86 RouterOS machines.
Primarily Dell servers with either Intel 82547GI, or Broadcom NetXtreme BCM5721 GBe controllers.
Other industrial class x86 machines with 82575EB/82574L and 82801G chipsets.

All Ethernet ports always indicate 'running'. This has been going on for quite a few releases back as far as I can remember, but it is now causing me logistical problems. (Are you sure you have link status?...NO I am not!)

ROS tells me all ports are 'running', but if you go to port status, it indicates proper link state, i.e. auto-negotion=done (with no connection), speed=unknown, with no connection to port whatsoever...

RBs dont seem to have this problem. I would hope someone else could corroborate this behaviour, but cant figure out why this hasnt been noticed before. Maybe I am missing something, but there are a lot of these types of machines and chipsets running ROS out there for years.

MT, anyone, please advise.....

This should be a FAQ entry.
disable-running-check (yes | no; Default: yes) Disable running check. If this value is set to 'no', the router automatically detects whether the NIC is connected with a device in the network or not.

On x86, disable-runnning-check in "/interface ethernet" defaults to "yes". Set it to "no" to get a true reading.

I'm curious, in what circumstances one would want to set disable-running-check=yes ?

I can't think of a single scenario.

Learn a new thing every day. Thanks for solving the now obvious mystery. Also cant find a reason why it shoud be in that default condition. Idiosyncrasy of ROS on x86... 8)

that is historic, when x86 boxes was not this powerful as they are today and drivers lacked cheep possibility to check state - it was set to disabled, to not to strain weak CPU with cheap network adapter.
