Traffic goes down in offpeak time to 1G. Difference between inbound and outbound traffic cannot be seen. The next day peak time the situation repeats - outbound traffic reaches a limit and does not go upper. Reboot resolves the situation. > Are there any drops/errors on this interface?

Uplink is connected to catalyst 6500: c6500-BGW-XL#sh int te3/6 | i flow input flow-control is on, output flow-control is off So as I see uplink shouldn't send pause frames.
