IENT ERR1

Error Description: ADAPTER ERROR

This error indicates that the Ethernet controller is malfunctioning.

DETAIL DATA

Return Code The error return code as defined in the /usr/include/sys/errno.h file.
Status Code For internal use only.
Program Check Code For internal use only.

IENT ERR2

Error Description: CONFIGURATION OR CUSTOMIZATION ERROR

This error indicates that the Ethernet device could not be activated because it could not obtain the necessary resources. The resources include DMA channels, interrupt level, bus memory space, and system memory space.

IENT ERR4

Error Description:

This error indicates that the Ethernet driver is experiencing a shortage of system-wide mbuffers (clusters).

OR

The Ethernet driver recieved an invalid packet size.

OR

The Ethernet driver failed to free memory.

OR

The Ethernet driver failed an action command.

DETAIL DATA

Return Code
816 mbuffer/cluster shortage. Verify the mbuffer watermarks using the no command. A possible fix is to bump up the following watermarks until errors are no longer being reported (the tradeoff is pinned memory usage):
  • lowclust
  • lowmbuf
  • thewall
  • mb_cl_hiwat.
683 An invalid package size was received.
1407, 162 Memory could not be freed up.
1829 An action command failed.
Status Code The system control block command or status word.
Program Check Code The return code.

For information concerning tuning system mbuffers, refer to the AIX Versions 3.2 and 4 Performance Tuning Guide, order number SC23-2365.

IENT ERR5

Error Description: COMMUNICATIONS SUBSYSTEM FAILURE

This error indicates that a transmission problem has been encountered.

DETAIL DATA

Return Code The error return code, as defined in the /usr/include/sys/entuser.h file.
