Network outbound errors can include dropped, discarded, or errored packets that couldn't be transmitted by the network interface. + +### What are outbound packet errors? + +Outbound packet errors occur when a network interface is unable to transmit packets due to issues like network congestion, hardware problems, or misconfigurations. A high number of outbound packet errors can indicate problems in the network and affect the performance of the virtual machine, resulting in poor application responsiveness and reduced bandwidth. + +### Troubleshoot the alert + +1. Verify the virtual machine's network configuration. + - Check virtual machine settings in vSphere to ensure the correct network adapters are assigned and configured properly. + - Check the virtual machine's guest operating system network configuration for possible errors or misconfigurations. + +2. Monitor vSphere network performance counters. + - Review the network performance counters in vSphere to identify issues or bottlenecks that might be causing the outbound packet errors. + +3. Check the physical network. + - Verify the physical network connections to the virtual machine, including cabling, switches, and routers. + - Inspect the network hardware to ensure proper functioning and identify faulty hardware. + +4. Evaluate network congestion. + - High network traffic can cause congestion, leading to increased outbound packet errors. Evaluate the network's current usage and identify potential bottlenecks. + +5. Review vSphere network policies. + - Check the network policies applied to the virtual machine, such as rate limiting or other traffic shaping policies, that may be causing the increased rate of outbound packet errors. + +6. Examine applications and services. + - Review the applications and services running on the virtual machine to determine if any of them are generating excessive or abnormal network traffic, resulting in outbound packet errors. + +### Useful resources + +1.
