Enabling IPSEC 3DES in PIX 515E

Answered Question
Jun 27th, 2007


I have this PIX 515E (HA) with IPSEC 3DES disabled. How should I enable it? Should I need an activation key to enable it? Do I need to purchase it? What's the impact in a production firewall if I load a new activation key? How should I load it?

Hi Danilo

You can register for a free 3DES license from Cisco. Go to this link

(you need a login but i'm assuming you have one ?)


You will get a new activation key. You can load it on a production system without impact but you need to do a reboot for it to take effect.
