On Solaris an 'underflow' is an error due to a busy bus. How loaded is your system?

What type of network are you on? Shared or Switched? The numbers of error that you are seeing are not condusive to having different duplex speeds at either end of your connection.

If you are running a shared network, then you might be seeing 'backoff' errors. Errors when the shared segment is too busy. (Even though your number of collisions is showing as 0)

If you are running a switched network.. then I don't know what the problem might be. What type of switch are you connected to?

Below is the out put from ifstat. I'm wondering what could be causing the errors in both the TRANSMIT and RECEIVE sections, and why the Underflow in the TRANSMIT section.

Could(are) the errors and Underflows in the TRANSMIT section be related?
