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
