Note If you are using a CORBA connection and require notifications, the router must be explicitly configured for each client
that is to receive notifications. These notifications include real-time inventory updates (for example, online insertion
and removal [OIR]), alarms, and change-of-configuration events. See the “Configuring the Router and CWI Client”
section on page 4 for information on configuring the router to send notifications to a specified client.
These prerequisites sections are described:
•Router Prerequisites, page 3
•CWI Client Prerequisites, page 3
•CWI Client System Requirements, page 3
Router Prerequisites
The router prerequisites ensure that the router is correctly set up. Before logging in to a router using CWI, you must meet the
router prerequisites that are described in Table 1.
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 CWI client.
Contact your system administrator to obtain the following information required to configure the router for use with CWI:
•Router hostname
•CWI client IP address if the client DNS name is not registered in a DNS server accessible by the router
CWI Client System Requirements
These sections list the CWI client hardware and software requirements. The CWI client hardware requirements ensure that the
CWI client has the proper verified system requirements for the chosen platform.

Item Task Additional Information

Base image and
manageability PIE
Ensure that the base image and manageability pie are
installed and running on the router to which you are
connecting using CWI client. Optionally, install and
activate the Cisco IOS XR Security Package (K9SEC) to
enable SSH and SSL functionality.
See Cisco IOS XR System Management
Configuration Guide for information on
how to start the base image.
Minimum router
configuration
Set the minimum router configuration before configuring
the CWI client and required Management Services
—
TTY or CORBA
connection method
Ensure if that connectivity is established between the
router Management Ethernet interface and CWI client.
See CiscoIOS XR Getting Started Guide
for information on connecting an
Ethernet interface from CWI client to the
router.
AAA1 username and
password
1. AAA = Authentication, Authorization, and Accounting
Configure at least one username and password on the
router. A valid AAA username and password for accessing
