Chapter 4 Configuring General Router Features

Connecting and Communicating with the Router

	Command or Action	Purpose
Step 3
	Power on the router.	Starts the router.
		• This step is required only if the router power is not on.
		• For information on power installation and controls, see
		the hardware documentation listed in the “Related
		Documents” section on page x.
Step 4
	Identify the target RP or DRP.	Identifies the RP or DRP to which you connect in the next
		step.
		• This step is not required when the router hosts only one
		RP or DRP.
		• On a Cisco CRS-1 router, the active RP or DRP is
		identified by a lighted Primary LED on the RP front
		panel.
		• On a Cisco XR 12000 Series Router, the active RP is
		identified by the alphanumeric display: ACTV RP.
		• If you cannot look at the RPs, use a Management
		Ethernet interface connection to determine which RP is
		active, or establish terminal server connections to both
		RPs and then try both.
Step 5
	telnet access-server-address port	Establishes a Telnet session with the terminal server.
		• Replace access-server-addresswith the IP address of
		the terminal server, and replace port with the terminal
		server port number that connects to the target RP
		Console port.
Step 6
	Press Enter.	(Optional) Initiates communications with the RP or DRP.
		• If no text or router prompt appears when you start the
		Telnet session, press Enter to initiate communications.
		• If the router has no configuration, the router displays

Step 7
	Log in to the router.	Establishes your access rights for the router management
		session.
		• Enter a username and password when prompted.

Establishing a Connection Through the Management Ethernet Interface

The Management Ethernet interface allows you to manage the router using a network connection. Before you can use the Management Ethernet interface, the interface must be configured, as described in the “Configuring the Management Ethernet Interface” section on page 4-41.

Once configured, the network connection takes place between client software on a workstation computer and a server process within the router. The type of client software you use depends on the server process you want to use. The Cisco IOS XR software supports the following client and server services:
