CCNA 7.3.c: Licensing

Overview:

Licensing refers to the IOS feature sets authorized to run on the device

 

Study Notes:

  • Today, there are two major versions of IOS images: 12 and 15
  • IOS version 12 has eight different feature sets to choose from depending on the services you choose to run on your device
FEATURE SET SERVICES
IP Base Entry level IOS image
Advanced Security Firewall, IPSEC, 3DES, VPN, SSH

Enterprise Base Multi-protocols, IBM support
Service Provider Services MPLS, SSH, ATM, VoATM

  • Licenses either come as temporary evaluation licenses (typically 60 days) or permanent licenses
  • The license status will display as either "Active, In Use" or "Inactive"
  • Typically, the router will come with IP Base and you would purchase any additional licenses required
  • The additional licenses will come with a Product Authorization Key (PAK)
  • Use the PAK, the Serial Number of the device and the Product ID of the device to generate the license
    • The SN and PID can be found on the pull-out tab attached to the device
    • The UDI is the PID concatenated with the SN
  • Use one of the following options to generate the license file
  • Next, you will receive an email with the license and instructions on installing it on your device
  • Copy the license file to your device the same way you would copy an IOS image using TFTP or FTP
  • Useful commands:
