Possible Causes

The sudden traffic volume change percentage in the inbound direction of interfaces exceeded the trap threshold.

Procedure

Run the display this interface command to view the Input bandwidth utilization field, and check whether the sudden traffic in the inbound direction of interfaces is normal.
- If so, no action is required.
- If not, check whether a loop exists on the link.
Collect log information, and contact technical support personnel.
