Remote transfer of rotated log files

Only the TFTP protocol is supported for remote transfer, and both IPv4 and IPv6 addresses are supported.

Only newly rotated log files are transferred to the remote host during the log rotation. Previously rotated log files are not transferred. After a file is successfully transferred, it is removed from the switch local path.

Packet level failures with TFTP are handled in the protocol itself. With each TFTP session failure, TFTP retries the file transfer three times. Retries have a timeout of five seconds.
