All the 32 ports can be configured as 100G or 40G.

Breakout is supported only on 24 ports of the C9500-32C switch model. Every 4th port of C9500-32C does
not support breakout due to ASIC limitation. Port numbers 4, 8, 12, 16, 20, 24, 28 and 32 do not support
breakout. When you enable breakout on a native port, the port numbering convention changes from 3-tuple
to 4-tuple. For example, if you enable breakout on port number 2 which is represented as Hu1/0/2, four logical
ports are created which are represented as Hu1/0/2/1, Hu1/0/2/2, Hu1/0/2/3 and Hu1/0/2/4.
