uploading firepower TS files to cisco faster with Customer eXperience Drive (CXD)

One of the big pains dealing with firepower is TAC will ask for TS files a lot. They take a long time to generate then you have to return to the FMC to download them, sometimes they can be 1gig or so and finally you need to upload them to the case. Cisco have made it a bit faster with cxd.

When you open you case with cisco, make note of the case number. Click the button to generate the token.

Log into the CLI of your FMC via ssh
expert
sudo su
curl -k https://cxd.cisco.com/public/ctfr/firepower.py | python - -c [CASE#] -t [TOKEN] --auto-upload &

Do the same on the active FTD as well.

You can move on with your day and the TS files with automatically generate and upload to the case.
