Known Affected Releases
12.2(33.1) 15.2(4)S 15.3(3)S 15.3(3.3)S3 15.4(1)S 15.4(2)S 15.4(3)S 15.5(2)S
Symptom: ESP fails to initialize and reboots. A message like the following will be seen on the IOS console: *Jan 01 16:22:35.562: %CPPHA-3-INITFAIL: F0: cpp_ha: CPP 0 initialization failed - startup init (0x1) *Jan 01 16:22:35.562: %CPPHA-3-INITFAIL: F0: cpp_ha: CPP 0 initialization failed - start CPP (0x1) The cpp_driver tracelog contains an entry which lists an A41C error code, indicating that the driver was unable to turn on termination. Here is an example: 01/01 16:22:35.120 [cpp-drv]: (ERR): COMP0053/dui/A41C: QFP0.0 - unable to turn on termination for DUI0 This is an intermittent failure, so the ESP will likely initialize successfully on the 2nd or 3rd attempt. This is an initialization issue, and once initialization completes successfully there are no further problems related to this condition. Conditions: Only ASR1002-x, ESP100 and ESP200 are affected. Router configuration or traffic pattern do not affect this problem. The software is fixed in XE3.7.6S, XE3.10.4S, XE3.11.2S, XE3.12.0S and later releases.
