Resolved Issues
| ID | Customer tracking number | Summary | Found in version | Resolved in version |
|---|---|---|---|---|
| 44703 | 44695 (Support) | Timestamp sampling in multiple event streams causes thread starvation | 3.24.2 | 3.25.8 |
| 44593 | 44589 (Support) | When an NT200A01 is placed in a non-bifurcated slot, it shows "Pair matching failed for 0" in the log as an error. | 3.24.2 | 3.25.8 |
| 44448 | 44372 (Support) | Documentation on how to use the HeaderStripper with MPLS and VLAN packets is missing. | 3.24.1 | 3.25.8 |
Known issues
| ID | Customer tracking number | Summary | Found in version |
|---|---|---|---|
| 44664 | The tool osmode has initial support for so-called bonding (link aggregation) because the tool checks the link status each second. The up/down status of the virtual interface (ntxs<number>) reflects the physical link state, which enables the (Linux) bonding driver to detect when a link is down and thus perform failover. This behavior is available on FreeBSD and Linux but not Windows. | 3.25.6 | |
| 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 -> 5.11 (64-bit)
The software has been qualified on: CentOS 7 and Ubuntu 20.04
