That is the reason for resetting the interface if there are Tx frames still on the ring. > I am suggesting to just clean the TX ring in question of this occurs.

If you don't reset the ring what you run the risk of is a data corruption and/or Tx hang when the link comes back up. - Alex ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
