Cisco ASA: Updating and Copying files from USB

KB ID 0001377

Problem

Cisco ASA firewalls have had USB sockets on them for a while, but a dig into the documentation only yielded, ‘for use in future releases’. Well they are working now!

Cisco ASA Upgrade from USB

Note: Firewall shown is a 5516-X (running version 9.8(1))

Solution

Your drive will get mounted as ‘Drive1’ (unless you have a secondary flash drive onboard already).

You can then copy the files to the main flash (disk0).

PeteASA(config)# copy disk1:/anyconnect-linux64-4.5.01044-webdeploy-k9.pkg disk0:
