Product Overview
All the 32 ports can be configured as 100G or 40G.
Port Type
100G native ports
40G native ports
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.
