Chapter 3 Assigning the Switch IP Address and Default Gateway
Checking and Saving the Running Configuration
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, protecting access to privileged EXEC commands,
and setting time and calendar services, see Chapter 6, “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

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 networks 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.
