APAR status

  • Closed as program error.

Error description

  • Some ethernet adapters cause transmit failures in
half duplex mode with 10 MBPS speed.
GOENT_TX_ERR errors will be seen in the error log.
.
After the transmit errors, the adapter hangs and
only way to recover is to reboot.
.
Look for collision errors as a signature for this
problem.
.
The affected adapters are FC (feature code):
5701
5706
5740
5767
5271
5717

Local fix

  • Use full duplex mode to work around this issue.

Problem summary

  • GOENT_TX_ERR errors in AIX error log when running the
Ethernet adapter 10Mbit Half Duplex mode.

Problem conclusion

  • Increase Tx timeout value to 1000 milliseconds to allow for
deferred transmits and transmit collisions which can occur
in a half duplex environment.
