This document describes the step-by-step procedure on how to regenerate certificates in Cisco Unified Communications Manager (CUCM) release 8.X and newer. It is critical for successful system functionality to have all certificates updated across the CUCM cluster. The tomcat-trust VeriSign_Class_3_Secure_Server_CA_-_G3 is no longer used. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. endobj Of course step when using CA signed certs, in step two, you will need to create a CSR, have it signed and import the cert back into ONLY the server on which the CSR was generated.

Wait for the phone registration to complete before you proceed to next certificate. This feature blanks out the ITL entries in the ITL file, so the phones trust any TFTP server.

This process of phones registration can take some time. Be advised, devices that had bad ITLs prior to regeneration process do not register back to thecluster until ITL is remove. Download and install RTMT Tool from Call Manager. Note:If a CAPF certificate expires, phones that use LSC are not able to register to CUCM because CUCM rejects their certificate.

Do not delete the five base certificates which include the CallManager.pem, tomcat.pem, ipsec.pem, CAPF.pem and TVS.pem. This is an issue where deleted certificates continue to reappear after removal. Certificate Regeneration Process For Cisco Unified Communications Manager (CUCM): the guide describes the process to regenerate the certificates by type, this is the most used and the recommended process. Only service certificates (certificate stores that are not labeled with -trust) can be regenerated. Encrypted configuration files do not work. Note: If this does not exist, do not worry. When you reboot the phone, it downloads the configuration and then contacts CAPF in order to update LSC. For example, the Cisco Manufacturing CA certificate is provided on CUCM trust stores to specific features and does not expire until the year 2029. <>/Rect[36 483.13 235.39 495.13]>> Phones do not authenticate for Phone VPN, 802.1x, or Phone Proxy. endobj This process of phones registration can take some time. Repeat for every Call Manager node in your cluster. 5) Regenerate the CAPF.pem certificate on the publisher CM server followed by regenerating it on the subscriber CM and then restart CAPF service only on publisher CM. <>/Rect[36 550.67 285.41 562.67]>> endobj Flexibility - Addition or removal of trust certificates are automatically reflected in the system. 12 0 obj There are a couple of types of certificate types: As said, there is a big chance all these need to be regenerated because they were generated at the same time: during install. endobj Wireless phones use 3rd party Certificate Authorities (CA) in order to authenticate themselves. However, a Certificate Authority (CA) can issue certificates for nearly any range of time. Each node has its own service certificates, this means that each pub and sub have a CallManager, Tomcat, IPsec, TVS and CAPF certificate. If the issue is already in the phone, it does not remove the ITL and the ITL removal needs to be manual. After running "set web-security" Tomcat must be restarted for the new certificate to be used when accessing CCMAdmin and CCMUser. (invalid_anc11) It is recommended to first regenerate all the expired Service Certificates in all the nodes, and CUCM updates the -trust copy automatically. Note: This feature only prevents, but does not fix ITL issues.
