Known Issues
NOTE: iSCSI Known Issues and FCoE Known Issues are located in their own sections of this
manual.
Lost Data Packets caused by Frequent LLDP Packets on an Inactive Port
When ports are teamed or bonded together in an active/passive configuration (for example, in a switch fault
tolerance team, or a mode 1 bond), the inactive port may send out frequent LLDP packets, which results in
lost data packets. This may occur with Intel ANS teaming on Microsoft Windows operating systems or with
channel bonding on Linux systems. To resolve the issue, set one of the ports to be the Primary port.
Code 10 yellow bang errors on a Virtual Machine in Windows Device Manager
On a system running Microsoft Windows Server 2016, inside a Virtual Machine running Microsoft Windows
Server 2016 or Windows Server 2012 R2, Intel Ethernet connections may have a code 10 yellow bang in
Windows Device Manager. Installing a cumulative updated that contains Microsoft KB3192366 and
KB3176936 will resolve the issue.
Dropped Receive Packets on Half-Duplex 10/100 Networks
If you have an Intel PCI Express adapter installed, running at 10 or 100 Mbps, half-duplex, with TCP Segment
Offload (TSO) enabled, you may observe occasional dropped receive packets. To work around this problem,
disable TSO or update the network to operate in full-duplex or 1 Gbps.
Throughput Reduction After Hot-Replace
If an Intel gigabit adapter is under extreme stress and is hot-swapped, throughput may significantly drop. This
may be due to the PCI property configuration by the Hot-Plug software. If this occurs, throughput can be
restored by restarting the system.
CPU Utilization Higher Than Expected
Setting RSS Queues to a value greater than 4 is only advisable for large servers with several processors.
Values greater than 4 may increase CPU utilization to unacceptable levels and have other negative impacts
on system performance.
Supported SFP or SFP+ Module Not Recognized by the System
If you try to install an unsupported module, the port may no longer install any subsequent modules, regardless
of whether the module is supported or not. The port will show a yellow bang under Windows Device Manager
and an event id 49 (unsupported module) will be added to the system log when this issue occurs. To resolve
this issue, the system must be completely powered off.
Windows Known Issues
Intermittent Link Loss and Degraded Performance at High Stress Can Occur on Windows Server
2012 Systems
In a Windows Server 2012-based system with multi-core processors, possible intermittent link loss and
degraded performance at high stress may occur due to incorrect RSS processor assignments. More
information and a Microsoft hotfix are available at: http://support.microsoft.com/kb/2846837.
