Hi guys,
One of the physical interface which is member of a port-channel with VPC is flapping with logs below.
It is happening a couple of times per day.
The physical link(10GBase-LR) status looks good - TX/RX Power levels are in normal range with no CRC/errors.
Any ideas what would cause this issue?
