Router Prerequisites
The router prerequisites ensure that the router is correctly set up.
You must meet the following router prerequisites before logging in to a router using the CWI:
• Ensure that the Base image and Manageability pie have been installed and running on the router that you will be connecting
to using the CWI client. Optionally, install and activate the Cisco IOS XR Security Package (K9SEC) to enable SSH and SSL
functionality, and the MPLS pie to enable a Multiprotocol Label Switching (MPLS) configuration. See the
Cisco IOS XR Getting Started Guide for information on how to start the base image.
• The minimum router configuration must be set before configuring the CWI client and required Management Services.
• For TTY or CORBA connection methods, ensure that connectivity is established between the router Management Ethernet
interface and the CWI client. See the Cisco IOS XR Getting Started Guide for information on connecting an Ethernet
interface from the CWI client to the router.
• At least one username and password must be configured on the router. A valid authentication, authorization, and
accounting (AAA) username and password for accessing the router must be configured. See the Cisco IOS XR Getting
Started Guide for information on configuring usernames and passwords on the router.
CWI Client Prerequisites
Ensure that the CWI client is correctly set up to communicate with the router. You should test the client connection. No special
configuration is required on the CWI client.
Contact your system administrator to obtain the following information required to configure the router for use with the CWI:
• Router hostname.
• CWI client IP address if the client DNS name is not registered in a DNS server accessible by the router.
4 Setting Up the Router and CWI Client
This section provides the procedures that must be completed, in sequence, before you can start using the CWI. The procedures
include setting the minimum router configuration that will allow the router to communicate with the CWI client, configuring
the required Management Services, and configuring the CWI client.
See the Cisco IOS XR Getting Started Guide for information on the capabilities of the router, installing Cisco IOS XR software
packages on the router, and booting up the router.
Setting Up Secure and Nonsecure Client Connections
When setting upthe requiredManagement Services, youhave theoption of communicatingbetween the CWI client andrequired
Management Services using SSL (secure connection) or no SSL (nonsecure connection).
The following two sections provide procedures for setting up the required Management Services with or without a secure
connection:
• Setting Up the Required Management Services Without a Secure Connection, page 8
• Setting Up the Required Management Services with a Secure Connection, page 8
The “Testing the CWI Client” section on page 10 provides information on setting up the CWI client after the required
Management Services are set up. The “Troubleshooting Basic IP Connectivity” section on page 11 provides information on
resolving connectivity problems.
