Transferring CoreDump file
If there is a coredump file available then transfer to external FTP/TFTP server. To transfer the file from the controller to a server, enter these commands:
(Cisco Controller) >transfer upload datatype coredump
(Cisco Controller) >transfer upload filename <desired filename>
(Cisco Controller) >transfer upload mode <tftp/ftp>
(Cisco Controller) >transfer upload serverip <ip>
(Cisco Controller) >transfer upload start
(You may need to specify file path as well, and username/password for FTP)
If you are using an FTP server, also enter these commands:
(Cisco Controller) >transfer upload username username
(Cisco Controller) >transfer upload password password
(Cisco Controller) >transfer upload port port
The default value for the port parameter is 21.
To view the updated settings, enter this command:
(Cisco Controller) >transfer upload start
When prompted to confirm the current settings and start the software upload, answer y.
After the file is uploaded, it ends with a .gz suffix. If desired, you can upload the same core dump file multiple times with different names to different servers.
Currently, it is cli only and no gui option.
