[c-nsp] C6500 - linkChange

[Andrew Miehs]

Hi all,

I have a pair of C6500s running s72033-ipservicesk9-mz.122-33.SXI3.bin and
am seeing the linkChange counters slowly increasing (roughly 300 per day)
on some of the interfaces on my WS-X6748-GE-TX line cards.

Has anyone seen this before?
The boxes have an uptime of almost 3 years.

Thanks for any comments,

Regards
Andrew
