Hi All,
Sorry to hear you are being impacted by this issue. I took a look at
the bug, and it is in a holding pattern, waiting until we can get some
logs from an impacted device - in order to root cause it. Can I ask
that anyone impacted please open a TAC case so they can assist with
getting the necessary logs to make forward progress?
Thanks much,
David White

...answering to Lucas and James:
We have EXACTLY the same behavior. And it's worrying that the bug notes
do not include all this info.
We have hundreds of these boxes in our networks but just recently we
approached this time limit.
Until now ALL the boxes that have passed the time limit have experienced
the same abnormal behavior.
Release notes of 15.6(2)SP5 (which we are thinking to upgrade) show this
bug as still open.

Has anyone been hit by CSCvk35460?
We have definitely been hit by this bug on two ASR920s running 03.16.02aS with
over 2 years of uptime.
The symptoms and effect of the bug from our observation include:
- packets continue to forward, so there is no immediate disruption to traffic
- interface counters stop increasing, snmp probing of the box fails with all
interfaces returning 0
- interface link state stops. if an interface goes down (e.g. due to fiber cut
or someone unplugging link), port will continue to remain up on IOS XE. this
creates lot of annoying operational problems.
- due to the above, new interface being plugged in will not come up, so you can
no longer provision new ports.
- DOM monitoring dies. attempting to show transceiver stats will freeze the
terminal for several seconds then error out.
Our reaction to this bug was to simply upgrade SW to at least 03.16.04 or newer
(03.16.06 and .07 seem to have completely broken MPLS FRR) and reload, but it
seems this bug is not fixed at all?
James
