C3850-NM-2-10G Module
In the C3850-NM-2-10G module, the first two parts are natively 1-G ports and the last two ports are natively
10-G ports. So, you configure the 1-G posts as GigabitEthernet1/1/1 through GigabitEthernet1/1/2, and
configure the last two ports as TenGigabitEthernet1/1/3 through TenGigabitEthernet1/1/4, even when you
are operating the last two ports as 1-G. Only four interfaces are valid, and the other four should not be used
even though they still show up in the CLI.

C3850-NM-8-10G Module
All ports in the C3850-NM-8-10G module default to 10 G and should be configured as TenGigabitEthernet1/1/1
through TenGigabitEthernet1/1/8, even when you are operating them as 1 G using SFP.
