Hello Guys,

Any idea ?

This is happening with almost every gig interface for node migrated to IOS-XR. But yes there is no customer complaint.

Hello Yigal,

Nice to know that you are active on community .

Well answers to your questions.

Is this drop rate is a concern?

     > No. And that is the reason I did not log tac case and prefer to get answer from community.

What is the plim type?

     > SPA-1X10GE-L-V2

What's going on the other ports on that plim?

      > Port is admin down (Teng0/6/1)

Have you tested L1?

      > Yes, 24 hour test without any issue found.

Can u get the plim asic stat?

      > command (sh controllers plim asic statistics interface <>) is not working since this is GSR.

However I am sharing few command output of one of the node which might be useful.

Regards

Mahesh

Hi everyone,

Logged tac case with cisco and as per Tac the problem could be because of Bug:CSCti75606.

Desc: Input drop counter increaing in output of show interface eventhough there is no actual drop observed.

This will be fixed in 3.9.3 version. Thanks Yogal for valuable time.

Regards

Mahesh
