[f-nsp] NP egress buffer on CES

[Kevin Cherry]

In our experience when this happens it due to hardware failing which progressively gets worse over time.  Normally after opening a case, TAC sends us a complete CES with 10G module and we replace the unit.

Thanks

I see similar messages on our old CER2024 gear, even when the 2x10G
interfaces are unused and disabled:

cer2024#sh int brie
...
2/1  Disabled None None None  None  No  level0 748e.f838.6531
2/2  Disabled None None None  None  No  level0 748e.f838.6532
...

cer2024#sh log
...

threshold for interfaces 2/1 to 2/2.
