Title: [SOLVED] Interfaces always UP even if cable are unplugged
Post by: farsoft on September 06, 2016, 05:00:06 pm

Hello everybody.

This is my first post.

I’ve bought two Deciso OPNsense A10 Dual Core SSD appliances in order to set up a HA cluster.

Everything seemed to work correctly but when I’ve started to do some failover tests, I’ve noticed that when I shut down the interfaces on the switches side or even if I unplug the network cables from any of the OPNsense interfaces, the status remains “active”.

If I disable / enable OPNsense interfaces from the GUI, then the status changes to “no carrier”. If I plug the cables, the interfaces go UP but if I unplugged again, the interfaces remain “active”.

I've got same behaviour in both appliances.

For instance, now the cable at em0 interface is unplugged but here is the status of the interface:

em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=4209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWTSO>
        ether f4:90:ea:10:17:a8
        inet6 fe80::f690:eaff:fe10:17a8%em0 prefixlen 64 scopeid 0x1
        inet 172.31.167.85 netmask 0xffffff00 broadcast 172.31.167.255
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        media: Ethernet 1000baseT (1000baseT <full-duplex>)
        status: active

My OPNsense version is 16.7.3-amd64.

I’ve searched at the forum and googled also but I haven’t found any similar problem.

Have you got any idea, please?

Thank you very much.

Regards.

Hi farsoft,

It's a bug in FreeBSD's intel driver, which is a modified version of the original from intel unfortunately.
We very recently discovered this one, after we already spend quite some time searching for another issue with the same driver which made IPS unusable.

There is however a very simple fix, you can install the intel original driver using ports and disable the FreeBSD default one.

Code: [Select]

pkg install intel-em-kmod

Then add the following to your /boot/loader.conf:

Code: [Select]

if_em_updated_load="YES"

Next reboot and all should be fine again.

We probably will add some gui code to handle this easily in a later version,

Best regards,

Ad

Hi Ad,

Thank you very much for your answer.

I will install the original Intel driver tomorrow morning.

I will keep you informed.

Best regards,

Hi again Ad,

I confirm that everything works fine with Intel's original driver.

Thank you very much!

A plugin named "os-intel-em" will be available with 16.7.4 onward.

We are currently debating if we should make it the default for 17.1. Opinions welcome. :)
