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.
