Things got funnier...
before my international hop I have two 7304 (being one of them the one
where the int'l connection is) and if I test connectivity between
them, I'll miss a ping packet every 10 seconds. All other packets make
it in 1ms or less, but every ~10 seconds I miss a ping.
I have already changed the SFPs and patch cords on these connections,
have even replaced both NPE-G100 on the 7300s. I still have those
hicups.
No CoPP is configured, and I can feel this symptom when accessing
remote terminals...
What could it be besides hardware? The 10s constant makes me think of
some recurring process, but can't find anything.
