(problem resolved)We use the switch S5721-28X-SI-24S-AC. The upstream port of the switch shows 100% utilization. Live traffic only reaching 200Mb.
Please help locate the fault. Thank you.

 The g0/0/1 speed is 10, and theduplex is half, that’s why the same traffic, g0/0/1 interface utilization is100%. Please check the peer device of g 0/0/1, what interface bandwidth does ituse? and does it use the auto-negotiation? By default the interface usethe auto-negotiation, and if the auto mode can’t make the speed and duplex worknormally, Try to change the speed andduplex mode manually.
