Debug logging for interface flaps.

Hi all,

We’re getting some 10G SFP flaps on a CRS305-1G-4S+IN (RouterOS 6.45.7)

Although there are some similar posts about this, I’d first like to get some more debug logging output. So far, all I can see is the up/down:

mar/24 17:43:55 interface,info sfp4 link down
mar/24 17:44:00 interface,info sfp4 link up (speed 10G, full duplex)
mar/24 17:44:11 interface,info sfp4 link down
mar/24 17:44:17 interface,info sfp4 link up (speed 10G, full duplex)
mar/24 17:44:30 interface,info sfp4 link down
mar/24 17:44:35 interface,info sfp4 link up (speed 10G, full duplex)

I’ve tried adding a log action of

interface,debug

but it produces nothing beside the above. Is there anything I can add to see more information about what’s happening? I can look in realtime at

/interface ethernet print stats

and

/interface ethernet monitor

, but since I can’t trigger a script to run them on an interface state change, it’s of limited use in catching the state at the point of the flap.

Any other suggestions welcome. :slight_smile:
