Troubleshooting Basic IP Connectivity
This sectionprovides information on troubleshooting basic IP connectivityproblems when attempting to log in toa 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 of the router.
If this step fails, the problem is an incorrect hostname to IP address mapping. See the “Router Prerequisites” 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 in to the router from the CWI login screen, run the Troubleshooter application at the prompt. See the
Cisco Craft Works Interface User Interface Guide for information on using the Troubleshooter application.
5 Getting Started with the CWI
This section describes the procedures for establishing a connection between the CWI and a router. The procedures are described
in the following sections:
• CWI Login Information Requirements, page 11
• Starting the CWI, page 12
• Logging In to Multiple Logical Routers, page 17
• Logging Out of a Logical Router, page 18
• Closing the CWI, page 20
When starting the CWI and logging in to a router, you always log in to a single router. After you have logged in to a single
router, you can log in to and manage multiple routers, but you must log in to each one separately. Each router appears in the
CWI Desktop Inventory Tree. For more information, see “CWI Desktop Window” section on page 21.
CWI Login Information Requirements
Contact your system administrator to obtain the following information required to complete the procedures in this section:
• The hostnames (DNS names) or IP addresses of any routers you want to log in to.
• Valid username and password for each router you want to log in to using the CWI. The username and password for each
router is your AAA username and password for that router. Therefore, each router may have a different username and
password.
