We have a stack of 3 6430 switches and their TX/RX utilization is impressively high, like 1 million packets in 2 minutes on each port (we have a ringed stack using 2 ports on each unit, so it's 3x2 ports).
For example, in 3 hours : 881 071 912 packets have been sent through one stacking port. Yes : 800 millions in 3 hours.
The cpu usage is also very very high (98%). It seems that we have a loop or something. But every ethernet port doesn't show high utilization. Only the stack ports are transmitting a lot of packets.
We are using the firmware version 7.4.
Any idea on how to fix this ?
