Manually Assigning IP Information
Beginning in privileged EXEC mode, follow these steps to manually assign IP information to multiple
switched virtual interfaces (SVIs):

Note
If the switch is running the IP services feature set, you can also manually assign IP information to a port
if you first put the port into Layer 3 mode by using the no switchport interface configuration command.

To remove the switch IP address, use the no ip address interface configuration command. If you are
removing the address through a Telnet session, your connection to the switch will be lost. To remove the
default gateway address, use the no ip default-gateway global configuration command.

default gateway receives IP packets with unresolved destination IP
addresses from the switch.
