Connecting Through the Management Ethernet Interface

The Management Ethernet interface allows you to manage the router using a network connection. Before using the Management Ethernet interface, configure it as described in the “Configuring the Management Ethernet Interface” section on page 3-35.

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:

•Telnet clients can connect to a Telnet server in the router. The Telnet server is disabled by default and can be enabled with the telnet ipv4 server command in global configuration mode.

•Secure Shell (SSH) clients can connect to an SSH server in the router. The SSH server is disabled by default and can be enabled with the ssh server command in global configuration mode. The SSH server handles both Secure Shell Version 1 (SSHv1) and SSHv2 incoming client connections for IPv4 address families.

To start a Telnet network connection, you start the Telnet client software with a command similar to the following:

telnet ManagementEthernetInterfaceIPaddress

For specific instructions on connecting to the router through a Telnet or SSH client, see the instructions for that software.

Ask your system administrator for the IP address of the Management Ethernet interface.

When the Telnet session is established, the router prompts you to log in, as described in the “Logging In to a Router” section on page 3-5.

Logging In to a Router

The login process can require users to enter a password or a username and password before accessing the router CLI. The user groups to which your username is assigned determine which commands you can use.

Once you log in to the router, you can manage the entire router.

When you log in, the username and password may be validated by any of the following services:

•Usernames configured on the router (username command in global configuration mode)

•Root-system usernames that are configured

•Passwords configured for the router console and auxiliary ports (password or secret command in line configuration mode)
