least 1G is used for collection of a the full core dump.
Example
This example enables core dumps to a TFTP server 10.27.9.1 reachable over
the out-of-band port. The core file is written to the dumps directory and the
name includes the host name of the switch and the switch TOD.
console(config)#exception dump tftp-server 10.27.9.1 file-path dumps
console(config)#exception core-file hostname time-stamp
console(config)#exception protocol tftp
