/mcpError Message %UC_CALLMANAGER-2-TCPSetupToIMEFailed: %[ip=String][port=UInt][AppID=String] [ClusterID=String][NodeID=String]: Connection Failure to IME server. Explanation This alarm occurs when Unified CM is unable to establish a TCP connection to an IME server. It typically occurs when the IP address and port of the IME server are misconfigured or an Intranet connectivity problem is preventing the connection from being set up. Recommended Action Check to make sure that the IP address and port of the IME server - which are present in the alarm - are valid. If so, this may be due to a network connectivity problem. Test the connectivity between Unified CM servers and the IME server. Error Message %UC_CALLMANAGER-1-TLSConnectionToIMEFailed: %[SSLErrorCode=UInt][SSLErrorText=String] [AppID=String][ClusterID=String][NodeID=String]: TLS Failure to IME service. Explanation A TLS connection to the IME server could not be established because of a problem with the certificate presented by the IME server. (For example, not in the Unified CM CTL, or is in the CTL but has expired). Recommended Action Check to see that the certificate of the IME server is configured properly in the UCM. Error Message %UC_CALLMANAGER-1-InvalidCredentials: %[usr=String][ip=String][Server=String][AppID=String] [ClusterID=String][NodeID=String]: Credential Failure to IME server. Explanation The connection to the IME server could not be completed, because the username and/or password configured on Unified CM do not match those configured on the IME server Recommended Action The alarm will include the username and password which were used to connect to the IME server, along with the IP address of the target IME server and its name. Log into the IME server and check that the username and password configured there match those configured in Unified CM. Error Message %UC_CALLMANAGER-1-IMEOverQuota: %[Server=String][Current quota=UInt][Maximum target quota=UInt][AppID=String][ClusterID=String][NodeID=String]: IME over quota. Explanation Each IME server has a fixed quota on the total number of DIDs it can write into the IME distributed cache. When this alarm is generated, it means that, across all of the Unified CM clusters which are utilizing the same IME server, the quota for the IME distributed cache has been exceeded. Recommended Action The alarm will include the name of the IME server, and the current and target quota values. The first thing to check is to make sure that you have correctly provisioned the right set of DID prefixes on all of the Unified CM clusters sharing that same IME server. If that is correct, it means you have exceeded the capacity of your IME server, and you require another. Once you have another, you can now split your DID prefixes across two different IME client instances, each on a different IME server. That will alleviate the quota problem. 5/24/26, 3:34 AM System Error Messages for Cisco Unified Communications Manager 15 - Cisco https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/err_msgs/15_x/ccmalarms15.html 285/343
