We have 2x8600 in the $core and 5520(ver 5.0.7.017) as access layer(stacked x2). So for some switches observe strange behavior - 1 of 2 uplinks is working, another is not.
we checked fiber, gbics.
So it seems the problem is with STP, all looks good from the configuration point of view.
And yesterday, we made some changes on the core trying to find the problem, after we lost both links connections between 5520 and 8600, but...leds on working connection are the same - seems good.
SMLT is set to normal.
And we have loose of ping every 4 is ok, then loose.
