[j-nsp] Meaning of xeth_ifdconfig: ifd 197, invalidated from pm_db

[Joerg Staedele]

Hi there,

We have a 10G link (LR) to a customer that went down yesterday and today (after 24h and 1 minute) and I have no clue why. There are no CRC errors or anything, the link just goes down for 1 second. The other side (Cisco) does not go down.

On the DPC I see the following but I am unsure if this is just because of the flap or indicating where the problem is:

[Oct 28 08:33:40.684 LOG: Debug] xeth_ifdconfig: ifd 197, invalidated from pm_db
[Oct 28 08:33:40.940 LOG: Debug] xeth_ifdconfig: ifd 197, invalidated from pm_db

JunOS is 12.3R8.7 on MX480, the affected port is on a DPC-R-4XGE-XFP. There are other ports on the same DPC that work fine.

Maybe someone has an idea.

Thanks and Regards,
 Joerg
