What is the meaning of Switchport mode trunk?
switchport mode trunk: Puts the interface into permanent trunking mode and negotiates to convert the neighboring link into a trunk link. The interface becomes a trunk interface even if the neighboring interface is not a trunk interface. switchport nonegotiate: Prevents the interface from generating DTP frames.
How do I get Switchport mode?
To display information about all the switch port interfaces, use the show interface switchport command.
Why do we use no Switchport command?
As mentioned above, the no switchport command is mainly used to configure routed ports. This helps Layer 3 switch reach the default router during the configuration of VLAN. This prohibits Layer 2 capabilities and enables Layer 3. Then you can assign an IP address to the routed port.
Why is the switchport mode access command important?
This command is important for any access port setting because without this command the port can be easily setup as a trunk interface. This command sets the port to access vlan 10. Without the switchport mode access command, if the neighbouring port is a trunk port, the port will be configured as a trunk.
What are the different types of switchport modes?

Without the switchport mode access command, if the neighbouring port is a trunk port, the port will be configured as a trunk. To confirm whether trunking has been disabled on an interface use the following command:
What’s the difference between switchport and switchport nonegotiate?
switchport mode access – Always forces that port to be an access port with no VLAN tagging allowed EXCEPT for the voice vlan. DTP is not used and a trunk will never be formed. switchport nonegotiate – turns off DTP and forces the interface into a trunk.
