Chapter 3 Assigning the Switch IP Address and Default Gateway
Assigning Switch Information
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, protecting access to privileged EXEC commands,
and setting time and calendar services, see
Chapter 7, “Administering the Switch.”
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 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.
