To access the switch remotely, an IP address and a subnet mask must be configured on the SVI:

For now the focus is IPv4; later you will explore IPv6.

You will learn the meaning behind all of these IP addresses soon, but for now the point is to quickly configure the switch to support remote access. The figure displays the command to enable IP connectivity to S1, using IP address

After these commands are configured, the switch has all the IP elements ready for communication over the network.

Note: The switch will still need to have one or more physical ports configured, as well as the VTY lines, to complete the configuration which enables remote management of the switch.

Practice configuring a switch virtual interface by entering commands in the figure.
