The first time a router is started, you must use a direct connection to the DSC Console port to connect to the router and enter the initial configuration. When you use a direct connection to the Console port, CLI commands are entered at a terminal or at a computer running terminal emulation software. A direct Console port connection is useful for entering initial configurations and performing some debugging tasks.

This chapter describes some of the tasks you might want to perform during your initial configuration. One of those tasks is the configuration of the Management Ethernet interface, which is described in the “Configuring the Management Ethernet Interface” section on page 4-39. After the Management Ethernet interface is configured, most router management and configuration sessions take place over an Ethernet network connected to the Management Ethernet interface. SNMP agents and the CWI also use the network connection.

The modem connection can be used for remote communications with the router and serves as an alternate remote communications path if the Management Ethernet interface fails.
