2 About the CWI

The CWI is a client-side application used to configure and manage routers. The management and configuration features include

fault, configuration, security, and inventory, with an emphasis on speed and efficiency.

The CWI provides a context-sensitive graphical representation of the objects in a router, simplifying the process of configuring

and managing the router. The CWI allows you to log in to multiple routers and perform the following management tasks:

•View, filter, sort, search, correlate, purge, and monitor real-time alarms.

•View, filter, export, and search real-time inventory and interface object attribute information.

•Display a dynamic graphical representations of routers.

•Telnet/Secure Shell (SSH) to the router for command-line interaction.

•Troubleshoot management connectivity problems.

The CWI provides three ways to configure and manage a router:

•Using a Telnet or SSH session launched from the CWI, which allows you to configure and manage the router using

command-line interface (CLI) commands.

•Using the Configuration Editor or Replace Configuration Editor, which allows you to view and edit the running

configuration in CLI format. The configuration editors provide common text editing functionality as well as traditional CLI

features. See the “Configuration Editor” section on page 22 and the “Replace Configuration Editor” section on page 22.

•Using the graphical configuration applications. See the “Configuration Desktop Window” section on page 20.

Support is provided to manage a two-stage commit functionality, which includes locking and rollback control.

3 Getting Started

This section provides information you need to know before you can start setting up a router and CWI client. The following

information is provided:

•Network Considerations, page 3

•Prerequisites, page 4

Network Considerations

The following network information must be taken into consideration before starting the minimum router and CWI client

configuration.

Basic Configuration

The basic configuration is not secure. See the “Setting Up the Required Management Services Without a Secure Connection”

section on page 8 for procedures.

Secure Socket Layer Encryption Configuration

The secure configuration has Secure Socket Layer (SSL) encryption. If you use the SSL protocol on your network, use the SSL

configuration. See the “Setting Up the Required Management Services with a Secure Connection” section on page 8 for

procedures.

IP Security

IP security (IPSec) does not require any special configuration for CWI on the router or client. See the “Setting Up the Required

Management Services Without a Secure Connection” section on page 8 for procedures.

Firewall

If you have a firewall in your network, you can use the basic or SSL encryption configurations. See the “Setting Up the Required

Management Services with a Secure Connection” section on page 8 and “Setting Up the Required Management Services Without

a Secure Connection” section on page 8 for procedures.

The ports listed in Table 1 must be opened when configuring the firewall. Refer to the firewall documentation for information

on opening the ports.

Table 1 Firewall Ports

Component Port Direction

HTTP/HTTPS 80/443 Inbound

IIOP/IIOPSSL 10001/10002 Inbound

Virtual Private Network

When setting the minimum router configuration you must use the client Virtual Private Network (VPN) IP address and Domain

Name Server (DNS) name instead of the client IP address and DNS name when configuring the IP hostname for the CWI client.

This mapping is required for the client to receive notifications from the router. See Step 3 in the “Setting the Minimum Router

Configuration” section on page 7.

If you have a VPN, you can use the basic or SSL encryption configurations. See the “Setting Up the Required Management

Services with a Secure Connection” section on page 8 and “Setting Up the Required Management Services Without a Secure

Connection” section on page 8 for procedures.

Dual-Homed

Dual-homed devices are used to bridge two networks. You can run an instance of CWI on the dual-homed device so that you

can access the secondary network. You will require terminal services or X-client software to run the CWI graphical application

from the client PC. A dual-homed device contains a client-side interface (IP address) and router-side interface (IP address). The

client-side is the primary interface, and the router-side is the secondary interface. (See Figure 1.)

Figure 1 Dual-Homed Device Configuration

When setting the minimum router configuration you must use the dual-homed device router-side (secondary) IP address and

DNS name when configuring the IP hostname for the CWI client. This mapping is required for the client to view the notifications

from the router received by the dual-home instance of CWI. See Step 3 in the “Setting the Minimum Router Configuration”

section on page 7.

If you have a dual-homed device in your network, you can use the standard or SSL encryption configurations. See the “Setting

Up the Required Management Services with a Secure Connection” section on page 8 and “Setting Up the Required Management

Services Without a Secure Connection” section on page 8 for procedures.

Prerequisites

Prerequisites ensure that the CWI client and router are correctly set up to allow them to communicate. Meeting all prerequisites

before starting any of the procedures in this guide is recommended to ensure successful communication between the CWI client

and router.

in this section.

Router Information Requirements

Contact your system administrator to obtain the following information required to configure the router for use with the CWI:

•Router hostname.

•CWI client DNS name.

•CWI client IP address if the client DNS name is not registered in a DNS server accessible by the router.

Note Before starting the procedures in this section, you must determine if the router will be running under Secure Socket

Layer (SSL).

To set the minimum router configuration, perform the following steps:

Step 1 Establish a Telnet/SSH session with the router.

Step 2 Enter configuration mode.

RP/0/RP0/CPU0:router# configure terminal

Step 3 Configure the IP host DNS name to IP address mapping for the CWI client.

Note If you are using a VPN or a dual-homed device in your network, the client IP address and DNS name are not

used when configuring the IP hostname for the CWI client. For a VPN, use the VPN IP address and DNS name.

For a network with a dual-homed device, use the dual-homed device router-side (secondary) IP address and

DNS name. See the “Network Considerations” section on page 3 for information on VPN and dual-homes

devices in a network.

RP/0/RP0/CPU0:router(config)# domain ipv4 host client-DNS-name client-IP-address

Step 4 Configure the hostname for the router.

RP/0/RP0/CPU0:router(config)# hostname router-hostname

Step 5 Exit configuration mode.

RP/0/RP0/CPU0:router(config)# commit

Setting Up the Required Management Services

When setting up the required Management Services, you have the option of communicating between the CWI client and required

Management Services using SSL (secure connection) or no SSL (nonsecure encryption).

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 “Setting Up 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 CWI Client Connectivity” section on page 10 provides information on

resolving connectivity problems.

Setting Up the Required Management Services Without a Secure Connection

This section provides the procedures required to set up the required Management Services without SSL.

Note The Telnet server must be enabled before you can manage a router using certain CWI features. These features include

the Telnet application, setting character displays in the Rack View application, and viewing committed configuration

changes using the Configuration Change dialog box. Refer to Chapter 4, “Bring Up a New Cisco CRS-1 Series Router,”

in the Cisco CRS-1 Series Carrier Routing System Getting Started Guide for information on enabling the Telnet server.

Note If you are connecting through a firewall in your network, the ports listed in Table 1 must be open before setting up the

required Management Services. Refer to your firewall documentation for information on opening the ports. See the

“Network Considerations” section on page 3 for information on firewalls in a network.

To start the required Management Services on the router, perform the following steps:

Step 1 Establish a Telnet/SSH session with the router.

Step 2 Enter configuration mode.

RP/0/RP0/CPU0:router# configure terminal

Step 3 Enable the HTTP server on the router.

Step 4 Enable the XML agent on the router.

RP/0/RP0/CPU0:router(config)# xml agent corba

Step 5 Exit configuration mode.

RP/0/RP0/CPU0:router(config)# commit

Setting Up the Required Management Services with a Secure Connection

This section provides the procedures required to set up the Management Services with SSL encryption. When setting up the

required Management Services and the CWI client with a secure connection, the certification authority (CA) and router

certificates must be set up before enabling the HTTP server and CORBA agent.

The following procedures are provided:

•Setting Up the Certificates, page 9

•Enabling the Secure HTTP Server and CORBA Agent, page 10

Note The SSH server must be enabled before you can manage a router using certain CWI features. These features include the

SSH application, setting character displays in the Rack View application, and viewing committed configuration changes

using the Configuration Change dialog box. Refer to Chapter 4, “Bring Up a New Cisco CRS-1 Series Router,” in the

Cisco CRS-1 Series Carrier Routing System Getting Started Guide for information on enabling the SSH server.

Note If you are connecting through a firewall in your network, the ports listed in Table 1 must be open before setting up the

required Management Services. Refer to your firewall documentation for information on opening the ports. See the

“Network Considerations” section on page 3 for information on firewalls in a network.

Note You must have the Crypto pie installed before attempting to complete the steps in this section. See the “Router

Prerequisites” section on page 6.

Setting Up the Certificates

Note The CA and router certificates have to be set up only once on a router. If the certificates have been set up, proceed to

the “Enabling the Secure HTTP Server and CORBA Agent” section on page 10.

To set up the certificates, perform the following steps:

Step 1 Establish a Telnet/SSH session with the router.

Step 2 Generate a Rivest, Shamir, and Adelman (RSA) key pair. Accept all prompted defaults.

RP/0/RP0/CPU0:router# crypto key generate rsa keypair-label

Note If the key pair label is not specified, “the_default” will be used.

Example:

RP/0/RP0/CPU0:router# crypto key generate rsa key1

Step 3 Enter configuration mode.

RP/0/RP0/CPU0:router# configure terminal

Step 4 Configure the CA trustpoint.

RP/0/RP0/CPU0:router(config)# crypto ca trustpoint ca-name

RP/0/RP0/CPU0:router(config-trustp)# enrollment url ca-URL

RP/0/RP0/CPU0:router(config-trustp)# rsakeypair keypair-label (This command must be completed if a

keypair label is specified in Step 2.)

RP/0/RP0/CPU0:router(config-trustp)# exit

RP/0/RP0/CPU0:router(config)# commit

Example:

RP/0/RP0/CPU0:router(config)# crypto ca trustpoint myca

RP/0/RP0/CPU0:router(config-trustp)# enrollment url http://myca/mydomain.com

RP/0/RP0/CPU0:router(config-trustp)# rsakeypair keypair-label

RP/0/RP0/CPU0:router(config-trustp)# exit

RP/0/RP0/CPU0:router(config)# commit

Step 5 Exit configuration mode.

RP/0/RP0/CPU0:router(config)# commit

Step 6 Authenticate the CA by getting the certificate for the CA.

RP/0/RP0/CPU0:router# crypto ca authentication ca-name

Step 7 Obtain a router certificate from the CA.

RP/0/RP0/CPU0:router# crypto ca enroll ca-name

Step 8 Verify that the router was granted a certificate. This command displays information about the router certificate and the

CA certificate.

RP/0/RP0/CPU0:router# show crypto ca certificate

Enabling the Secure HTTP Server and CORBA Agent

To enable the secure HTTP server and CORBA agent, perform the following steps:

Step 1 Establish a Telnet/SSH session with the router.

Step 2 Enter configuration mode.

RP/0/RP0/CPU0:router# configure terminal

Step 3 Enable the HTTPS server on the router.

RP/0/RP0/CPU0:router(config)# http server ssl

Step 4 Enable the XML agent with SSL.

RP/0/RP0/CPU0:router(config)# xml agent corba ssl

Step 5 Exit configuration mode.

RP/0/RP0/CPU0:router(config)# commit

Setting Up the CWI Client

Verify that you can connect to the router by logging in to the router. See the “Starting the CWI” section on page 11 for

procedures. If you are unable to log in to the router, see the “Troubleshooting CWI Client Connectivity” section on page 10.

Troubleshooting CWI Client Connectivity

This section provides information on troubleshooting connectivity problems when attempting to log in to a router using the

CWI.

If you are unable to connect to the router HTTP server using the browser, follow these steps in sequence, exiting the test steps

when a failure is encountered.

Step 1 Ping the IP address of the router management Ethernet interface from the client PC/workstation.

If this step fails, the problem can be an incorrect IP address, incorrect management Ethernet interface configuration, or

a network connectivity problem.

Step 2 (Optional) Ping the DNS name or IP address of the router.

If this step fails, the problem is an incorrect hostname to IP address mapping. See Step 3 in the “Setting the Minimum

Router Configuration” section on page 7.

Step 3 Check that the HTTP Server is running on the router using the following command:

RP/0/RP0/CPU0:router# show process emweb

If this step fails, start the HTTP server. See Step 3 in the “Setting Up the Required Management Services Without a

Secure Connection” section on page 8 or Step 3 in the “Setting Up the Required Management Services with a Secure

Connection” section on page 8.

If you are unable to log into the router from the CWI login screen run the Troubleshooter application at the prompt. Refer to

the Cisco CRS-1 Series Carrier Routing System Craft Works Interface User Interface Guide for information on using the

Troubleshooter application.
