3.20.0 |
| 43445 | Added support for CPU Socket Load Balancer feature when using the 8x10G (200-9539-23-xx) or the 2x40G (200-9540-23-xx) FPGA images. | 3.16.0 |
Resolved Issues
| ID | Customer tracking number | Summary | Found in version | Resolved in version |
|---|---|---|---|---|
| 43452 | 43319 (Support) | Undersized packets are not counted correctly on NT200A02-2x100 | 3.15.1 | 3.20.2 |
| 43448 | 43352 (Support) | NT4E fails to establish link at 100M | 3.6.1 | 3.20.2 |
| 43444 | 43058 (Support) | When plugging some types of SFP NIM modules e.g. AFCT-5715PZ one might experience that link is not obtained by the link partner because the laser is not turned on. Re-plugging might solve the problem but not always. | 3.14.0 | 3.17.1 |
| 43443 | NIM sensor reading for SFP's without DMI data e.g. trispeed NIM's will show constant values from reading non-existing sensor values. | 3.15.0 | 3.17.1 | |
| 43442 | 43143 (Support) | It might happen when disabling/enabling a port that the whole system becomes unresponsive. | 3.14.0 | 3.17.1 |
| 43440 | 43059 (Support) | The Streams view of the profiling tool displays a list of open streams/connections. If the list is empty, some key presses, e.g., pressing 'right arrow' or 'page down', will cause the tool to malfunction and stop its execution. | 3.14.0 | 3.16.1 |
| 43439 | 42873 (Support) | When having defined at least one "inline" transmission (tx) host buffer (i.e., having defined a stream), and when attempting to execute the NTPL statement "delete = all" while a program is retrieving data on the stream, the service may report "Tx TBH range error on Tx feed |
3.12.1 | 3.16.1 |
| 43438 | 43062 (Support) | ntservice crash occuring when the a KeyMatch test uses a KeySetId reserved for a Key test. | 3.15.1 | 3.17.2 |
| 43437 | 43135 (Support) | Time Skew is reported wrongly when using time format UNIX_NS with NT_TS time synchronization. Despite correctly sync'ed a very large skew is reported | 3.14.0 | 3.17.1 |
| 43435 | 43061 (Support) | When duallookup is off via ntservice.ini setting KmTcamConfig, the filter expression "IPMatch==DstIP" don't match incoming packets correctly.
Consequently, Retransmit expressions using IPMatch doesn't retransmit packets as expected. |
3.12.1 | 3.19.0 |
| 43434 | 43063 (Support) | Key test using NOT EQUAL, i.e. key(...) != ..." isn't configured correctly when no keys exist (i.e. no prior KeyList command). | 3.15.1 | 3.19.0 |
| 43433 | 42723 (Support) | Certain combinations of AND and OR in filter-expressions may trigger a buffer overflow | 3.11.1 | 3.19.0 |
| 43432 | 43032 (Support) | When the NTPL Assign command is used without the option StreamID, no default stream is created, resulting in packets hitting no filters rather than drop filters. | 3.14.0 | 3.19.0 |
| 43431 | 42701 (Support) | ntservice hanging if specifying more than 128 tx host buffers in ntservice.ini | 3.9.0 | 3.19.0 |
| 43430 | 43068 (Support) | When executing transmit_packet_example it is likely that not all packets are transmittet. | 3.14.0 | 3.20.0 |
| 43429 | 43314 (Support) | Some QSFP28 modules have build-in FEC support, and the consequence is, that link cannot be obtained, since the FPGA itself also applies FEC. | 3.13.4 | 3.20.2 |
| 43428 | 43120 (Support) | When transmitting a file using pktgen on a 4Generation adapter, the file is always transmitted in line rate. | 3.7.1 | 3.20.1 |
| 43427 | 43278 (Support) | Binary backward compatibility is broken. Using an application, that is not recompiled to the latest driver, can cause the application to crash. | 3.9.0 | 3.20.1 |
| 43426 | 43326 (Support) | Monitoring does not show IPF counters (7000, 7001, 9512, 9521, 9522, 9526) | 3.15.1 | 3.20.2 |
Known issues
| ID | Customer tracking number | Summary | Found in version |
|---|---|---|---|
| 42679 | 42677 (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 |
| 42678 | 42677 (fix) |
When using host loopback on NT200A01 without any NIMs plugged in, it is not possible to get link on a QSFP28-LR4 NIM inserted afterwards 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 |
| 38911 |
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. |
3.7.4 | |
| 38365 |
The performance of host based transmission may be degraded in the following scenario:
1. Local retransmit is taking place at full line rate on a subset of the ports of the adapter. 2. In parallel with 1., host based transmission is taking place on a separate port of the adapter (i.e. the combined host and local retransmit functionality is not used.) |
3.7.1 | |
| 36499 | When using the GlobalSync feature, link down/up events causes the port to enter 'unknown' state | 2.9.4 | |
| 11368 | When using a Cisco DAC pluggable, link is detected even if the other end of the cable is unplugged. | 2.7.0 | |
| 11366 | Setting TimeSyncTimeJumpThreshold for OS timesync to values > 0, will enable the time jump feature and results in a jump threshold of 1 second. | 2.6.0 |
