Chapter4 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) or ports:
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 lo st. 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 you entered or changes you made by entering this privileged
EXEC command:
Switch# show running-config

Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 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 when the e nh an ced
software image is installed and 1 to 1001 when the standard software
image is installed; do not enter leading zeros.
Step3 ip address ip-address subnet-mask Enter the IP address and subnet mask.
Step4 exit Return to global configuration mode.
Step5 ip default-gateway ip-address Enter the IP address of the next-hop router interface t ha t is di rec tly
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 t o the
remote networks with which a host needs to communicate.
Note When your switch is configured to route with IP, it does not ne ed
to have a default gateway set.
Step6 end Return to privileged EXEC mode.
Step7 show running-config Verify your entries.
Step8 copy running-config startup-config (Optional) Save your entries in the configuration file.
