    What does "K9" stand for ?

    Matthieu Malyga

      Hi everyone,


      maybe a stupid question but ... what does "K9" stand for (in "Cisco 3825-HSEC/K9" or "CISCO3825-CCME/K9" for example)?


      In a general manner, is there any document giving signification to all those Cisco acronyms?



      Thank you

          Not sure if it's an actual acronym. But the images with K9 in them typically refer to the image containing the abililty to do SSH. When you browse the downloads, you'll often see a certain feature set listed twice. For instance, "IPBASE" and "IPBASE with SSH". The SSH one is the K9 version.

            By the way, here is a link to an article that talks about IOS numbering and image naming that may help a bit.

              K9 Product bundels have strong AES/3DES encryption.

              K8 Product bundels have weaker DES encryption.


              Cisco is an American company which is bound to Export restriction.

              Strong encryption is seen by law as a wapon. For American companies it is forbidden

              to export strong encryption to "asses of evil" counties like Iran or North Korea.


              K8 / K9 is Cisco's way of tagging these product.


              On cisco.com/go/license you can get free K9 encryption licenses.

              Of course you have to declare, you are not exporting your product to these countries.


              With this license you can turn e.g. a ASA5510-BUN-K8 into a ASA5510-BUN-K9

                The K9 image consists of strong cryptographic features such as AES/3DES encryption



                Cisco is an American company which is bound to Export restriction and are controlled under the U.S. Export Administration Regulations and Wassenaar Arrangement as telecommunications/networking equipment within the following classifications: 5A991, 5D991, 5E991 5A992, 5D992, 5E992, 5A002, 5D002, and 5E002.



                Cisco solutions and products containing 64-bit or less encryption may be delivered to most end users worldwide, except to entities or end users in the following countries: Cuba, Iran, North Korea, Sudan, and Syria.



                SKU codes K8 and K9 is Cisco's way of identifying these products.


                From the Licensing Portal (cisco.com/go/license) you can request for a free K9 encryption license. As a requirement, you need to accept and declare that you are not exporting Cisco's product to embargoed destinations and countries designated as supporting terrorist activities. Countries listed in Part 746 of the EAR as embargoed destinations requiring a clearance are Cuba, Iran, North Korea, Sudan, and Syria.
