Significado de IOS - encriptación

Buen día

necesito conocer el significado de la información que contiene los caracteres o partes que conforman el IOS, por ejemplo, sé que c2600 define que está corriendo o funciona para la serie de routers 2600.

Específicamente necesito extraer del IOS si este encrypta, en cuál o qué forma o tipo, además de los demás datos intrínsicos que otorga las partes que conforman el IOS.

Creo que la parte en donde se indica "kx" es la que indica si encripta o no y el tipo o forma en el que lo realiza.  Pero necesito más información  orientación

Agradeciendo la colaboración y el compartir sus "tips".



Re: Significado de IOS - encriptación


Could you please post your question in english?

To answer your questions, the ''kx'' shows encryption.

For example:

System image file is "flash:c2600-ik9o3s3-mz.122-15.T9.bin"

  • The c2600 tells me this is for the 2600 series of routers.
  • The i in ik9o3s3 tells me that this is the IP routing version of the IOS.
  • The k9 tells me that this is the 3DES encryption version of the IOS.
  • The o3 tells me that this is the Firewall/IDS version of the IOS.
  • The s3 tells me that this is the "Basic limited routing / limited memory" version of the IOS for the 2600 and 3600 series routers.
  • The mz tells me that this version of the IOS runs from RAM and is compressed.
  • The 122-15.T9 tells me that this is IOS version 12.2, patch level 15, and "training" version 9.
  • Hope it helps.

    The document "White Paper: Cisco IOS and NX-OS Software Reference Guide" is very useful to detect
    the release family, current version and some other details...

    But if you really want to know what services and features an IOS image supports you can always check the IOS feature navigator.

    You will get a list with the capabilities of that IOS image.
