Check duplex setting end to end ( host to out side network)
If it is on specific time use esxtop check which daemon is generating high traffic.
Thanks for the reply,
It is not at a specific time. All nics are set to auto negotiate. How would this cause high network traffic?
What kind of Hardware Monitoring Software you are using ? Check the time interval and frequency or Hardware/ Software polling scheduled on the Monitoring software. At times if you have the time set to perform the Polling is very frequently then it could be the reason you are seeing lot of traffic . You can change the interval of polling on the Monitoring Software and keep it under observation.
