Uuencode flash dump
show flash-dump-uuencode
Command mode: All
Using this command, dump information is presented in uuencoded format. This format makes it easy to
capture the dump information as a file or a string of characters.
If you want to capture dump information to a file, set your communication software on your workstation to
capture session data prior to issuing the command. This will ensure that you do not lose any information.
Once entered, the command will cause approximately 23,300 lines of data to be displayed on your
screen and copied into the file.
Using the above command, dump information can be read multiple times. The command does not cause
the information to be updated or cleared from flash memory.
Dump information is not cleared automatically. In order for any subsequent dump information to be
written to flash memory, you must manually clear the dump region. For more information on clearing the
dump region, see the “Clearing dump information” section later in this chapter.
