Known Issues
Internal Ref. | Issue |
3200779 | Description: Changing dynamic PCIe link width is not supported. |
Workaround: N/A | |
Keywords: PCIe | |
Discovered in Version: 26.34.1002 | |
2169950 | Description: When decapsulation on a packet occurs, the FCS indication is not calculated correctly. |
Workaround: N/A | |
Keywords: FCS | |
Discovered in Version: 26.34.1002 | |
3141072 | Description: The "max_shaper_rate" configuration query via QEEC mlxreg returns a value translated to hardware granularity. |
Workaround: N/A | |
Keywords: RX Rate-Limiter, Multi-host | |
Discovered in Version: 26.34.1002 | |
2870970 | Description: GTP encapsulation (flex parser profile 3) is limited to the NIC domain. Encapsulating in the FDB domain will render a 0-size length in GTP header. |
Workaround: N/A | |
Keywords: GTP encapsulation | |
Discovered in Version: 26.34.1002 | |
2866931 | Description: When the host powers up directly into the standby mode, the adapter may not handle WOL packets. |
Workaround: N/A | |
Keywords: WOL packets | |
Discovered in Version: 26.32.1010 | |
2864238 | Description: VPD cannot be accessed after firmware upgrade or reset when the following sequence is performed:
|
Workaround: Run the upgrade or reset sequence as follow:
| |
Keywords: VDP | |
Discovered in Version: 26.32.1010 | |
2780349 | Description: As a result of having a single LED per port, features such as the Blinking Detection can work only when in low speed mode. |
Workaround: N/A | |
Keywords: LED, port, Blinking Detection | |
Discovered in Version: 26.32.1010 | |
2834990 | Description: On rare occasions, when toggling both sides of the link, the link may not rise. |
Workaround: Toggle the port to free it. | |
Keywords: Port toggling, link | |
Discovered in Version: 26.31.1014 | |
2667681 | Description: As the Connection Tracking (CT) is not moved to SW state after receiving a TCP RST packet, any packet that matches the windows even after the RST is marked as a valid packets. |
Workaround: N/A | |
Keywords: Connection Tracking | |
Discovered in Version: 26.31.1014 | |
2378593 | Description: Sub 1sec firmware update (fast reset flow) is not supported when updating from previous releases to the current one. Doing so may cause network disconnection events. |
Workaround: Use full reset flow for firmware upgrade/downgrade. | |
Keywords: Sub 1sec firmware update | |
Discovered in Version: 26.29.1016 | |
2213356 | Description: The following are the Steering Dump limitations:
|
Workaround: N/A | |
Keywords: Steering Bump | |
Discovered in Version: 26.29.1016 | |
2365322 | Description: When configuring adapter card's Level Scheduling, a QoS tree leaf (QUEUE_GROUP) configured with default rate_limit and default bw_share, may not obey the QoS restrictions imposed by any of the leaf’s ancestors. |
Workaround: To prevent such a case, configure at least one of the following QoS attributes of a leaf: max_average_bw or bw_share | |
Keywords: QoS | |
Discovered in Version: 26.29.1016 | |
2201468 | Description: Running multiple resets ("mlxfwreset --sync=1") simultaneously is not functioning properly, |
Workaround: Wait a few seconds until you run "mlxfwreset --sync=0". | |
Keywords: mlxfwreset, reset-sync, reset, sync | |
