Monitoring And Maintaining The Interfaces - Cisco Catalyst 3550 series Software Configuration Manual

Chapter 10 Configuring Interface Characteristics
Command
Step 7 show interfaces [interface-id]
show ip interface [interface-id]
show running-config interface [interface-id]
Step 8 copy running-config startup-config
To remove an IP address from an interface, use the no ip address interface configuration command.
This example shows how to configure an interface as a routed port and to assign it an IP address:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# no switchport
Switch(config-if)# ip address 192.20.135.21 255.255.255.0
Switch(config-if)# no shutdown
Switch(config-if)# end
This is an example of output from the show ip interface privileged EXEC command for the interface:
Switch# show ip interface gigabitethernet0/2
GigabitEthernet0/2 is up, line protocol is up
Internet address is 192.20.135.21/24
Broadcast address is 255.255.255.255
Address determined by setup command
MTU is 1500 bytes
Helper address is not set
Directed broadcast forwarding is disabled
