This chapter describes how to communicate with the router using command-line interface (CLI). This 
chapter also shows basic Cisco IOS XR Software configuration management.

To use a router running Cisco IOS XR Software, first connect to it using a terminal or a PC. Before you 
connect to the router, determine which entity to manage. You can manage router hardware or named 
RSPs.

Connections are made through a direct physical connection to the Console port or through management 
interfaces. To connect through the management interfaces, establish IP addresses and a default gateway. 

The first time a router starts, use a direct connection to the Console port to type the configuration 
information. When directly connected to the Console port, enter CLI commands at a terminal or 
computer running terminal emulation software. This direct Console port connection is useful for 
debugging as well.

Configure the Management Ethernet interface, described in the 

. Router management and configuration can take place over an Ethernet 

network connected to the Management Ethernet interface. Simple Network Management Protocol 
(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 is an alternate path.

The following sections describe how to connect to the router:
