Result
If DHCP was enabled on this interface, DHCP is now disabled. Any existing dynamically
learned IP address will be automatically converted to a static IP address.
If static IP addresses were configured and if no explicit IP address was transferred as a
parameter, all static IP addresses will be deleted from this interface.
If a static IP address was specified explicitly, this address is deleted from this interface.
Note
Effectiveness of the command
The command is effective immediately.
If you configure the interface via which you access the device, you can lose the connection!
Further notes
You assign an IP address with the ip address or ip address dhcp command.
