Getting and Applying License Files to ASA Firewalls

• Obtain the license files in the same way as with Nexus Switches (One exception: On the ASR, you get the Serial and UDI No with the command show license udi, the command show license host-id does not exist here.)
• Copy the .lic file to a USB thumb drive and insert the drive into the ASR's USB port.
• On the ASR, switch to enable and copy the .lic file to the bootflash drive: copy usb1: bootflash:
• Apply the license using the following command: license install bootflash:<filename>.lic
• Check if the license has been applied correctly using the sho license command
