Issue/Introduction
VMware ESXi hosts report repeated hardware soft errors in the `vmkernel.log`.
Log entries:
`health_check: CRT HW SOFT ERROR: Code=0x11F4 Reg=te_nic_int_sts_1``health_check: CRT HW SOFT ERROR: Code=0x0924 Reg=rxp_int_sts_2`
Where there is potential intermittent network flapping or degraded throughput.
Environment
VMware ESXi 8.0
Cause
Transient hardware interrupt or memory bit-flip within the NIC's internal registers, that are corrected by the device firmware.
Resolution
1. Through ESXi CLI, SSH into the host and Capture the `vmnic` name associated with the hardware address `0x8243001C` and `0x80214E18`.
esxcfg-nics -l- Look which one matches up to log snippet.
2. Validate the NIC Driver and Firmware versions against the Broadcom Compatibility Guide for I/O devices.
3. Update the NIC firmware to the latest vendor-approved version to improve error-handling logic.
* If the error persists after firmware updates, consult your hardware provide to see if the physical NIC or motherboard if the NIC is Onboard, should be replaced.
