LSC validation is failing on a new SCCP IP phone you have just added to the Cisco Unified
CallManager 5.0 cluster. No other IP phones are experiencing any problems with LSC validation.
What can you do to help pinpoint the problem?
A.
View the SDI trace output.
B.
Check for security alarms.
C.
Use the security configuration menu on the IP phone to verify that an LSC has been
downloaded to the IP phone.
D.
Verify that the authentication string is correct in the Cisco Unified CallManager device
configuration screen.
Explanation:
Troubleshooting If the Locally Significant Certificate Validation Fails
On the phone, the locally significant certificate validation may fail if the certificate is not the version
that CAPF issued, the certificate has expired, the CAPF certificate does not exist on all servers in
the cluster, the CAPF certificate does not exist in the CAPF directory, the phone is not registered
to CiscoCallManager, and so on. If the locally significant certificate validation fails, review the SDL
trace files and the CAPF trace files for errors.
You can verify that the locally significant certificate installed on the phone by choosingSettings >
Model Informationand viewing the LSC setting. The LSC setting displaysInstalledorNot
Installed, depending on the circumstances.
