It is worth a quick check the NIC on the Teradata side...

We had a similar issue here...

Per the GSC:
---------------------------------------------

There are two commands you can use to check network configuration on the node:

/etc/ildconfig may show the information, depending on the card or the driver.

The is a xxxdatarate (where xxx is the driver, like iee or e1000) command in the /etc/ild directory. There is a man page for usage, the PPA will be the one returned by ildconfig

There is also a file in /etc/default/xxx (see above) that controls the way the cards are initialized.

If you suspect there is a mismatch, try /etc/ild/macstats <PPA> -e. (find PPA via the /etc/ildconfig).

If you are supposed to be running full duplex, there should be no collisions.

---------------------------------------------


We found that the issue had to do with a bug that caused our NIC to come up at half duplex when in-line power was turned on from the switch connected to our NIC. We have since turned off in-line power and reset the NIC. There is also a patch for this issue.
