C9300 shows 10/25/40Gbps ports In running configure while there is no module for those...

[SIMMN]

I have a C9300-24T-E with v16.9.5. The only module installed is NM-4G. All the ports are 1Gbps. But in running configuration, there are a number of tengigabitethernet, twentyfivegigabitethernet and fortygigabitethernet ports....

why? A new feature?

Those are just place holders for when you purchase and insert a module.

Is this a new feature on the C9K platform? What would be the benefit for this kinda placeholder?

[Reza Sharifi · Accepted solution]

This is not new. Traditionally the smaller switches have a place holders for uplinks. This way, the port numbering is predetermined.

See table-2 in this link.
