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:
Command
Step 1
configure terminal
Step 2
interface vlan vlan-id
Step 3
ip address ip-address subnet-mask
Step 4
exit
Step 5
ip default-gateway ip-address
Step 6
end
Step 7
show running-config
Step 8
copy running-config startup-config
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

Purpose
Enter global configuration mode.
Enter interface configuration mode, and enter the VLAN to which the IP
information is assigned. The range is 1 to 1001.
Enter the IP address and subnet mask.
Return to global configuration mode.
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.
When your switch is configured to route with IP, it does not need
Note
to have a default gateway set.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
