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.
Thank you for the useful post.
