The customer attempted to set the MTU parameter to 9000.

When we set the value to 9000 following happens :

 1. Instead of green light we see orange LED on data links in the BUI

 2. System complains about network settings

 3. We still can use the datalink and interface BUT:

      - IPMP does not seem to work
      - No decrease in TCP packets
      - BUI/CLI hangs , transfers slow down when a load is applied to the system through those links
