Background Information

When FTD or FMC troubleshoot takes place, there are times you have to download files from said devices, like a packet capture for analysis on an external tool or to provide files from your devices to Cisco TAC for Analysis. After the file to download has been identified this becomes a two step procedure, first, move the files to the correct location and, second, download the files from the FMC GUI.

Procedure

Move Files to the Correct Folder

FMC

In this example, you download a Core file from the FMC GUI that TAC requested for additional troubleshoot and root cause analysis.

Move File to /var/common folder

In this case, you have the Core file already on /var/common folder, however, you can move the file with the cp or mv commands to copy or move respectively, as shown in the image.

sudo su

{cp | mv} /<file_path>/<file_name> /var/common/

FTD

In this example, generate and download a show tech-support from the FTD and download it from the FMC GUI.

First, run the show tech-support command and redirect it, as shown in the image.

show tech-support | redirect disk0:/show-tech.log

Move File to /ngfw/var/common folder

In this case, as you saved the file on disk0, so you need to move it from /mnt/disk0 to /ngfw/var/common, as shown in the image.

sudo su

cd /mnt/disk0

{cp | mv} /<file path>/<file_name> /ngfw/var/common/
