I have a question about the N2048 setting deletion command.

1. I would like to delete some settings that are set on the interface.

Is the following command correct?

no channel-group
no description
no switchport access vlan
no spanning-tree portfast
no switcnport protected

Is it necessary to specify the logical port number or vlan number?

2. If I want to change the description, can I overwrite it by setting a new description without deleting it?

3. Are the following commands used to delete vlans and logical ports?

no vlan [vlan number]

no interface port-channel [channel number]

4. What does the 0 in switcnport protected 0 mean?
