“ERROR: Could not process request” when changing driver default settings.
4 Known problems and limitations
The following problems and limitations are known to exist in version B.11.31.1203.01:
•
Rx flow control must be disabled when Jumbo Frames are used.
Due to limitations of the hardware supported by the iexgbe driver, Rx flow control must be
disabled when Jumbo Frames (MTU value greater than 1500) are enabled. This limitation is
enforced by the iexgbe driver. Therefore, if the current configuration has Rx flow control
enabled while Jumbo Frames are used, the iexgbe driver might not honor changes made to
flow control settings or MTU size.
•
Flow control is disabled in Flex-10 mode
In Flex-10 mode, Tx/Rx Flow control is disabled by default. Attempts to enable flow control
are not honored by the driver, because the driver and hardware cannot determine whether
Jumbo Frames are disabled across all FlexNICs.
•
Rx flow control and Jumbo Frames cannot both be enabled in non-Flex-10 mode
In non-Flex10 mode, you can change the flow control and MTU size as needed. However,
Rx flow control and Jumbo Frames cannot both be enabled at the same time. If Jumbo Frames
are enabled, attempts to turn on Rx flow control will fail. Conversely, if Rx flow control is turned
on, attempts to enable Jumbo Frames will fail.
Workaround: Before attempting to enable Jumbo Frames, ensure that Rx flow control is disabled.
Before attempting to turn on Rx flow control, ensure that Jumbo Frames are disabled.
•
Resetting certain interface attributes can automatically cause flow control to be turned off
Directly or indirectly resetting any of the iexgbe attributes (such as mac, mtu, or vmtu) can
automatically cause Tx and Rx flow control values to be reset to the default (OFF).
•
Using ncweb to change number of receive queues causes an error message.
Severity: Medium
When you use the ncweb or SMH interface to change the number of receive queues, an error
message appears.
Workaround: Use nwmgr instead of ncweb to change number of the queues. The command
syntax is:
nwmgr -s -A drv_mq=
where
The number of queues that you want to enable.
Instance number of the LAN interface; for example, lan1.
