[c-nsp] IOS XR small amount of Input errors/DROP_FRM_FRM_ERR_XAUI

[Drew Weaver]

Hey all,

I have been going a little bit nutty trying to determine the source (and correct) some input errors on a Bundle-Ether (and its associated member interfaces) on IOS XR 5.1.1 it is a very low amount of errors: 5393 out of 36277989602736 but they are still incrementing. They increment in small bursts of 8 errors at a time on between 2 and 4 member interfaces.

The errors present themselves like this on the interface(s):

5393 giants, 0 throttles, 0 parity
5393 input errors

But they aren't actually giants, the actual bucket they are being put in on the NP is:

DROP_FRM_FRM_ERR_XAUI

So far we have:

Moved member ports to different SPAs in same slot
Moved member ports to different SPAs in different slot
Replaced all of the cables
Replaced all of the transceivers

Has anyone seen this before?

Thanks,
-Drew
