Input bandwidth utilization threshold : 100.00%
Output bandwidth utilization threshold: 100.00%
Input bandwidth utilization : 0.01%
Output bandwidth utilization : 0.01% Check whether the current state is UP, whether the interface speed is normal, whether the duplex mode is normal, and whether CRC errors exist.
If the current state is not UP, locate and rectify the fault according to Two Connected Electrical Interfaces Cannot Go Up or Two Connected Optical Interfaces Cannot Go Up.
