Resolved Issues
ID Customer tracking number Summary Found in version Resolved in version
44897 44895 (Support) The Napatech kernel module, nt3gd, would fail to compile with GNU/Linux kernel 5.18 (or newer) and with Red Hat 9 distributions, such as CentOS/Rocky/Oracle Enterprise Linux versions 9. 3.27.2 3.27.4
44896 44800 (Support) TX multiport buffers are limited to only 1 buffer per adapter. If more buffers are requested, ntservice fails with the error "NT_NetTxOpen_Attr() failed: HBM reports no free TX host buffers found". 3.27.2 3.28.0
Known issues
ID Customer tracking number Summary Found in version
44389 The FPGA images: 9504, 9508, 9515, 9537 and 9564, does not support dynamic descriptors. 3.27.0
44314 SFP+ dual-speed 1000BASE-T/10GBASE-T modules support 10G only 3.23.3
44312 Periodic problem for adapter installed in a x8-lane PCIe gen.3 supported slot and configured with 25G DAC
Workaround:
Reboot server
3.25.1
44286 The diode on both cards light up when using CU and TRI speed electrical plugables, regardless of link status. 3.25.1
43621 TX is not properly disabled on all ports when enabling host-loopback while using DAC cables, resulting in packets being transmitted from the adapter. 3.21.3
42948 Frequent CRC errors when using DAC cables shorter than 1 meter. 3.13.3
42936 The link diode extinguishes when the port is disabled as it should, but lights up again when the module is unplugged and reinserted with the port still disabled. No link is up. But the diode lights up as if there is. Status is read correct from software. 3.13.3
42652 42616 (fix) FEC cannot be changed dynamically on NT200A01, if traffic has been applied. Hence, it is not possible to dynamically swap between SR and LR QSFP28 if unless FEC has been disabled for SR modules in the ini file
Workaround:
If QSFP28-LR module is to be used then either plug it in before start-up of the system or set DisableFEC=TRUE in ntsevice.ini
3.11.1
42257 Dynamic hostbuffers are not supported by Intel PAC A10 accelerators.
Therefore NTAPI Inline features are not supported by Intel PAC A10 accelerators.
Workaround:
Applications using DPDK will support Inline for Intel PAC A10 accelerators.
3.9.1
41150 The Automatic over-temperature shutdown will only stop NT service, it cannot shutdown the Intel Programmable Acceleration Card Blue bitstream. 3.9.0
38699 Using NT_NetRxGet* or NT_NetRxGetMult* first time on newly created or reconfigured streams can lead to initial package drops when the system is configured with large hostbuffers or many client applications.
This will only be triggered on newly created and reconfigured streams.
Workaround:
If packet loss is observed, to get clean statistics no traffic should be received on connected ports while streams are being started.
3.7.5
32765 When using the GlobalSync feature, link down/up events causes the port to enter 'unknown' state 2.9.4
14086 If NUMA node zero is offline and /opt/napatech3/config/ntservice.ini does not exist, the driver cannot start because it fails to allocate memory for the default host buffer set-up.
Workaround:
Use an existing ntservice.ini or specify the host buffer set-up on an online NUMA node: '/opt/napatech3/bin/start.sh -o adapter0.BusId=0000:04:00.0 -o adapter0.AdapterType=NT40E3_4_PTP -o adapter0.HostBuffersRx=[4,32,1] -o adapter0.HostBuffersTx=[2,16,1]'. BusId and AdapterType are only required if there are multiple adapters in the server; the BusId can be obtained with 'lspci | grep Napa'.
2.8.5
10740 When using a Cisco DAC pluggable, link is detected even if the other end of the cable is unplugged. 2.7.0
9189 9137 (Support) The Linux kernel v3.8->v3.12 has a bug in the NUMA balancing code which was introduced in v3.8. See https://bugzilla.kernel.org/show_bug.cgi?id=60734
The issue causes high execution delays on cores running on other than NUMA 0 if the feature is enabled.
To work around the problem, disable the NUMA balancing by adding "numa_balancing=disable" to the kernel command line.
The Linux kernel 3.13 received significant NUMA updates which fixes this issue.
The 3.10 kernel in RHEL 7, CentOS 7 and Oracle Linux 7 (not the 3.8.13 uek kernel) contains a fix for this, thus the work around is not needed.
0.1.1
8719 Setting TimeSyncTimeJumpThreshold for OS timesync to values > 0, will enable the time jump feature and results in a jump threshold of 1 second. 2.4.1
4324 3GD requires at least gcc 4.0 to build and at least glibc 2.5 to run. 1.1.0

Operating systems

The following operating systems are supported:

  • Linux 3.0 -> 3.19 (64-bit)
  • Linux 4.0 -> 4.18 (64-bit)
  • Linux 5.0 -> 5.19 (64-bit)

    The software has been qualified on: Oracle Server Linux 9.1
