Anu,

 

You'll have to ask the working group. If the working group decide otherwise, I will update the MIB.

Hi,
      The Bandwidth units are in "thousand bps" and syntax is Unsigned32. With this we will be able to support only around 4000 Gigabit.
      But for optical links, the bandwidth might be greater than this.
Should we revisit this?

Regards,
Anu
