Usage Guidelines A switch can have one IP address.
The IP address of the switch can be accessed only by nodes connected to ports that belong to the
management VLAN. The default for the management VLAN is VLAN 1, but you can configure a
different VLAN as the management VLAN.
If you remove the IP address through a Telnet or Secure Shell (SSH) session, your connection to the
switch is lost.
If your switch receives its IP address from a Bootstrap Protocol (BOOTP) or a DHCP server and you
remove the switch IP address by using the no ip address command, IP processing is disabled, and the
BOOTP or DHCP server cannot reassign the address.
Examples
This example shows how to configure the IP address for the switch on a subnetted network:
Switch(config)# interface vlan 1
Switch(config-if)# ip address 172.20.128.2 255.255.255.0
You can verify your settings by entering the show running-config privileged EXEC command.
