Problem - No Session

You are unable to open a session to the CUE module or you do not see any output on the console.

Solution

You can use this command in order to check the console messages on the CUE module without the need to open a session to it:

Router# test service-module service-engine slot/unit console

By default, this command displays the most recent 80 lines stored in the console buffer. However, it is possible to specify an offset of greater or less than 80, or to view all the messages stored in the console buffer with this command:

Router# test service-module service-Engine slot/unit console ?
  <1-20456>  Offset into console buffer
  all        Entire console buffer
