You can access the CLI by using a direct console connection or by using a Telnet or SSH connection from a remote management host.
For the initial connection, you must use a direct connection to the console port. You cannot access the system remotely until the system has an IP address, subnet mask, and default gateway. You can set the network configuration information manually, or you can configure the system to accept these settings from a BOOTP or DHCP (Dynamic Host Configuration Protocol) server on your network. For more information, see Network Interface Commands.
