Chapter 3 Assigning the Switch IP Address and Default Gateway
Checking and Saving the Running Configuration
Switches B through D retrieve their configuration files and IP addresses in the same way.
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 image, 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, protecting 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 that you entered or changes that you made by entering this
privileged EXEC command:
Switch#
show running-config
Building configuration...
Current configuration: 1363 bytes
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 VLAN 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 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.
