An interface generates "bandwidth usage exceeded the log threshold" logs when it goes UP.
The interface Peak rate counters show that traffic is actually within limits.
The topology was analyzed and it was revealed there are no forwarding loops.
QoS rate limits were configured on the interface, but they did not take effect:
qos lr outbound cir 700000 cbs 87500000
qos lr inbound cir 700000 cbs 87500000
It was discovered that the access device connected to the interface was configured with 10Mbps Ethernet speed.
The 10Mbps speed was easily exceeded, causing the bandwidth usage logs.

Replace the access device NIC with a NIC capable of higher speeds.
