Troubleshooting Cisco Unified IP Phone Security Chapter 9 Troubleshooting and Maintenance Table 9-1 Cisco Unified IP Phone Security Troubleshooting (continued) Problem Possible Cause 802.1X Enabled on Phone but Not Authenticating Phone cannot obtain a DHCP-assigned IP address. Phone does not register with Cisco Unified Communications Manager. 802.1X Authentication Status displays as "Held" (see the "802.1X Authentication and Status" section on page 4-43). Status menu displays 802.1X status as "Failed" (see the "Status Menu" section on page 3). These errors typically indicate that 802.1X authentication is enabled on the phone, but the phone is unable to authenticate. 1. Verify that you have properly configured the required components (see the "Supporting 802.1X Authentication on Cisco Unified IP Phones" section on page 1-23 for more information). 2. Confirm that the shared secret is configured on the phone (see the "802.1X Authentication and Status" section on page 4-43 for more information). - If the shared secret is configured, verify that you have the same shared secret entered on the authentication server. - If the shared secret is not configured, enter it and ensure that it matches the one on the authentication server. 9-14 Cisco Unified IP Phone 7906G and 7911G for Cisco Unified Communications Manager 6.0 OL11954-01
