No connectivity to a
Fault Tolerance
bundle while using
network capture tools
(e.g., Wireshark)
This can happen if the network capture tool captures the network
traffic of the non-active adapter in the bundle. This is not allowed
since the tool sets the packet filter to “promiscuous”, thus causing
traffic to be transferred on multiple interfaces. Close the network
capture tool on the physical adapter card, and set it on the LBFO
interface instead.
No Ethernet
connectivity on 1Gb/
100Mb adapters after
activating
Performance Tuning
(part of the
installation)
This can happen due to adding a TcpWindowSize registry value. To
resolve this issue, remove the value key under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControl- Set\Ser-
vices\Tcpip\Parameters\TcpWindowSize or set its value to 0xFFFF
System reboots on an
I/OAT capable system
on Windows Server 20
This may occur if you have an Intel I/OAT capable system with
Direct Cache Access enabled, and 9K jumbo frames enabled. To
resolve this issue, disable 9K jumbo frames.
Packets are being lost
This may occur if the port MTU has been set to a value higher than
the maximum MTU supported by the switch.

Failed to reset the Mellanox ConnectX EN 10Gbit Ethernet NIC. Try
disabling then re-enabling the “Mellanox Ethernet Bus Driver”
device via the Windows device manager.
Failed to initialize the Mellanox ConnectX EN 10Gbit Ethernet
Adapter <X> because it uses old firmware version (<old firmware
version>). You need to update the adapter to firmware version <new
firmware version> or higher, and to restart your computer.
Mellanox ConnectX EN 10Gbit Ethernet Adapter <X> device
detected that the link connected to port <Y> is down. This can occur
if the physical link is disconnected or damaged, or if the other end-
port is down.
Mismatch in the configurations between the two ports may affect the
performance. When Using MSI-X, both ports should use the same
RSS mode. To fix the problem, configure the RSS mode of both
ports to be the same in the driver GUI.
Mellanox ConnectX EN 10Gbit Ethernet Adapter <X> device failed
to create enough MSI-X vectors. The Network interface will not use
MSI-X interrupts. This may affects the performance. To fix the prob-
lem, configure the number of MSI-X vectors in the registry to be at
least <Y>.
