Cisco Systems Cisco 7920 Error Message − No Service IP Config Failed, Incorrect WEP Keys

Page 49

Note: If you need help with the the text entry feature on the Cisco 7920, see the Background Theory section of this document.

1.Choose Edit Menu > Network Config > 802.11b Configuration > Wireless Settings > SSID > SSID1 > Specify .

When you are done, click OK.

2.Turn the Cisco 7920 off and back on again.

3.Refresh the Cisco Aironet 1200 AP Home page.

4.The Cisco 7920 should associate and authenticate with the Cisco Aironet 1200 AP.

If you are still having problems, then choose Setup > Address Filters to view the configuration.

a.Make certain that you have not setup a MAC address filter that blocks the Cisco 7920￿s MAC address.

b.If you have a wireless data client available, test it to see if it can associate and authenticate with the Cisco Aironet 1200 AP.

If it can, then compare the settings on it with the Cisco 7920. The Cisco 7920 must be able to associate and authenticate with the 1200 AP, to register with the Cisco CallManager server.

Cisco 7920 Error Message − No Service IP Config Failed

If the Cisco 7920 is setup to obtain its IP parameters from a DHCP server￿and it is not able connect to the DHCP server or the DHCP server is not able to provide an IP address to the Cisco 7920￿then the No Service IP Config Failed error message appears. A DHCP server problem or misconfigured WEP Encryption Keys cause this problem.

DHCP

Troubleshooting DHCP problems is beyond the scope of this document. Refer to Solving DHCP and TFTP Problems with Windows 2000 and CallManager IP Phones.

As an alternative you can use static IP parameters to eliminate the DHCP server from the configuration, so that you can continue to troubleshoot the Cisco 7920￿s registration process. See the Configuring the Cisco 7920 section of this document to configure a static IP address. Select an IP address from the appropriate subnet that is not already in use on the network. Turn the Cisco 7920 off and back on again, after you have configured the static IP address.

Incorrect WEP Keys

Incorrect WEP keys cause the Cisco 7920 to send IP packets that are not decrypted properly by the Cisco Aironet 1200 AP. This problem has the same symptoms as a loss of IP connectivity. Verify that the Cisco 7920 and the 1200 AP have the same WEP keys configured.

∙See Step 15 in Configuring the Cisco 7920 for information on Cisco 7920 Network Security..

∙See Step 6 in Configuring the Cisco Aironet 1200 AP for information on Cisco Aironet 1200 AP Radio Data Encryption.

If the Cisco 7920 registers with the Cisco CallManager server, you have successfully completed this task.
