Description (partial)

Symptom:
On certain 3750 switches, the special character "^@" is appended to the end of buffered logging messages.

Conditions:
The logging filter feature must be configured to trigger this issue. 

This is configured with the following two commands:
 
            logging filter <filter_file>
            logging buffered filtered
                                
This does not affect logging to the console.
