Connecting to and Communicating with the Router

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 “Configuring the Management Ethernet Interface” section on page 3-33. 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:
