Overview
Network Interface Card (NIC) with drivers with versions from January 2016 or earlier should be updated to avoid issues with packet storms behavior when waking from sleep.
Environment
- Intel® Ethernet Connection I217-LM
- Intel 82579
The problem has been isolated to version 11.15.12.0 of the Intel Net E1c62x64.INF and Intel Net E1c6232.INF drivers.
Root Cause
The problem occurs when the system goes to sleep or standby. The bug causes the NIC to start transmitting a sequence of 0’s to incrementing Media Access Control (MAC) addresses (starting at 00-00-00-00-00-00, 00-00-00-00-00-01, and so on).
If any of the affected systems go into a sleep state, there is a high possibility that the NIC will start transmitting a sequence of 0’s across the network. If proper security/data storm control is not enabled, the data can propagate and possibly bring down a switch or an entire section of a network.
Resolution
The solution is to upgrade to version 12.2.45.0 or newer of the NIC driver.
To update the required drivers, refer to Downloads for Intel® Ethernet Connection I217-LM.
