Cisco MARS license file

We have been redoing our whole network infrastructure over the last year and we are looking to put MARS in place. The appliance we have is version 3.4.3 and I'm looking to do a clean install to 4.3.x. The lic file however was already uploaded to the appliance. Is there a way to export this file to disk to I can upload it to the new version once the install is complete?


Re: Cisco MARS license file

Hi Joshua,

There is no way to export the key, re-image the box, and then import the license key. You need to write the key down if it isn't on the chassis. The 25 character license key should be printed on the front of the MARS appliance. If not, contact the people who sold you the appliance or who sell you the maintenance.

Hope this helps.

Ok thank you very much

Re: Cisco MARS license file

You can retrieve the license key you're using by clicking on "Admin", "System Maintenance", "Set License Key".

Write this key down, and remember that it is case-sensitive. The same key will work after you re-image the appliance.

Re: Cisco MARS license file

Thanks Gary,

I found after the reinstall and received a new license code from Cisco :) I now have it saved for future reference.

On a side note, I just purchased your book and the End-to-End Security by Omar Santos. I have ave read the first 3 chapters and have really found it beneficial with a great layout.

As I stated before, we purchased the box over a year ago (MARS-20), but I am just now getting the opportunity to implement it because of implementation of other end-point/perimeter security products (CSA, NAC appliance which I must say are a great tag team).

I'm really encouraged MARS will be a key piece to the puzzle with regards to our end-to-end security infrastructure
