Chapter 3 Assigning the Switch IP Address and Default Gateway
Checking and Saving the Running Configuration
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.
For information on setting the switch system name, pr
otecting access to privileged EXEC commands,
and setting time and calendar services, see Chapter 7, “Administering the Switch.”
Checking and Saving the Running Configuration
You can check the configuration settings you entered or changes you made by entering this privileged
EXEC command:
Switch# show running-config
Building configuration...
Current configuration: 1363 bytes

version 12.2
no service pad
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface vlan vlan-id Enter interface configuration mode, and enter the VLAN to which the IP
information is assigned. The range is 1 to 4094.
Step 3
ip address ip-address subnet-mask Enter the IP address and subnet mask.
Step 4
exit Return to global configuration mode.
Step 5
ip default-gateway ip-address Enter the IP address of the next-hop router interface that is directly
connected to the switch where a default gateway is being configured. The
default gateway receives IP packets with unresolved destination IP
addresses from the switch.
Once the default gateway is configured, the switch has connectivity to the
remote n
etworks with which a host needs to communicate.
Note When your switch is configured to route with IP, it does not need
to have a default gateway set.
Step 6
end Return to privileged EXEC mode.
Step 7
show interfaces vlan vlan-id Verify the configured IP address.
Step 8
show ip redirects Verify the configured default gateway.
Step 9
copy running-config startup-config (Optional) Save your entries in the configuration file.
