Version 7.7.1.0 Restructured the command to accommodate core dumps for CP. 
Introduced on the C-Series and S-Series.
Version 6.1.1.0 Introduced
Usage 
Information
You must use this command to enable core dump logging before a software exception occurs. 
If the FTP server is unreachable, FTOS aborts the application core dump.
When you enable this command to allow the system to automatically upload application core 
dumps to an FTP server, you are requested to enter a username and password. Use the 
username and password of the FTP server where the core files are being moved. The 
password can be up to 15 alphanumeric characters only; no special characters are allowed. 
After you enter the password, an FTP URL is created with the credentials in the operating 
system. The CLI monitors application core dumps in the unit. Any application core dumps that 
occur are automatically uploaded to the FTP server.
Because flash space may be limited, using this command ensures your entire crash kernel files 
are uploaded successfully and completely. You can only configure a single coredump server. 
Configuration of a new coredump server over-writes any previously configured server.
NOTE: You must disable logging coredump before you designate a new server destination 
for your core dumps.
