switchport mode dynamic

showint

I don't have such an option as switchport mode dynamic {desirable|auto} and switchport nonegotiateWhy don't I have this command? And how can I fix the issue?

Thanks

First thing is what type of switch do you have and the version of the IOS of the switch.

Is this a lab or a sim?

I use only virtual environment, not real, dut to a strong lack of money.

I've tested these commands on all possible types of routers with NM-16 ESW.

I found this command only in Packet Tracer.

Switchport module for routers may have different configuration options. Check cisco documentation for clarification.
