What is interfaceInputUtilizationHigh in cisco routers?

interfaceInputUtilizationHigh is a Cisco router SNMP (Simple Network Management Protocol) trap that indicates that the input traffic on a specific interface has exceeded a defined threshold, suggesting potential congestion or performance issues. This alert helps network administrators monitor the health of their network interfaces and take necessary actions to optimize performance, such as load balancing or upgrading bandwidth. It is part of proactive network management to ensure efficient data flow and prevent packet loss.
