Recommended Action Use RTMT to monitor the system memory resources and consumption and correct any system issues that might be contributing to a reduced amount of system resources. Error Message %UC_TFTP-6-BuildStat: %[DeviceCount=Int][DeviceTime=Int][UnitCount=Int][UnitTime=Int] [SoftkeyCount=Int][SoftkeyTime=Int][FeatureControlPolicyTime=Int][FeatureControlPolicyCount=Int] [DialruleCount=Int][DialruleTime=Int][TotalTime=Int][BuildStatus=String][AppID=String] [ClusterID=String][NodeID=String]: Device configuration files are being built.. Explanation This alarm provides information about the BUILD ALL operation to build all types of configuration files.

Error Message %UC_TFTP-3-IPv6InterfaceNotInstalled: %[AppID=String][ClusterID=String][NodeID=String]: IPv6 network interface is not installed.. Explanation IPv6 option is enabled for TFTP service but the IPv6 network interface/address has not been configured on the system. Until the IPv6 network is functioning, devices that have been configured with IPv6-only will not be able to register. Devices that have been configured to use either IPv6 or IPv4 will register using IPv4. When the IPv6 network is online, IPv6-capable devices that have registered as IPv4 will remain IPv4 until they are reset, at which time they will use IPv6 if available. Recommended Action Install IPv6 network interface and then restart TFTP service. Error Message %UC_TFTP-5-ITLFileRegenerated: %[AppID=String][ClusterID=String][NodeID=String]: ITL file regeneration.

Error Message %UC_TFTP-1-OFFClusternodedown: %[IpAddress=String][AppID=String][ClusterID=String] [NodeID=String]: OFFCluster node is down Explanation This is to indicate that the offcluster node is down. Recommended Action Proxy-offcluster configuration is enabled and this node is configured as an offcluster-node.Please ensure that TFTP service on offcluster node is up and running for the proxy- offcluster configuration to work properly.If it is not an intended configuration please uncheck the TFTP check box in cluster view configuration in UI. 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 63/343
