Chapter 3 Configuring General Router Features
Connecting and Communicating with the Router
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 information. When the router is directly connected to the
Console port, enter CLI commands at a terminal or at a computer running terminal emulation software.
This direct Console port connection is useful for entering initial configurations and performing some
debugging tasks.
This chapter describes some of the tasks 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 3-66. 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 also use the network connection.
You can use the modem connection for remote communications with the router. If the Management
Ethernet interface fails, the modem connection serves as the alternate remote communications path.
