Which IOS command do you use to remove Layer 2 configurations and return an interface to Layer 3 mode?

A. vlan

B. no vlan

C. switchport

D. no switchport








 

Suggested Answer: D

Use the no switchport command to remove Layer 2 configurations and return an interface to Layer 3 mode. The syntax of the command is: switch(config-if)# no switchport
The enhanced multilayer switch image must be installed on the switch to use this command.
The switchport command without the no keyword converts the port back to a Layer 2-switched interface. switch(config-if)# switchport
The vlan vlan-id configuration command is used to configure VLAN characteristics for a specific VLAN. Use the no keyword without additional parameters to delete a VLAN.
