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 |
| IP Voice | VoIP, VoFR, IP Telephony |
| Enterprise Base | Multi-protocols, IBM support |
| Service Provider Services | MPLS, SSH, ATM, VoATM |
| Advanced IP Services | IPv6, Advanced Security, Service Provider Services |
| Enterprise Services | Enterprise Base, Full IBM Support, Service Provider Services |
| Advanced Enterprise Services | Full Cisco IOS Software |
- In IOS version 15 the Feature Sets are condensed into four choices
| FEATURE SET | SERVICES |
| IP Base | Entry level IOS functionality |
| Data | MPLS, ATM, Multi-protocols, IBM support |
| Unified Communications | VoIP, IP Telephony |
| Security | IOS Firewall, IPS, IPSEC, 3DES, VPN |
- 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
- Cisco License Manager - http://www.cisco.com/go/clm
- Cisco License Registration Portal - http://www.cisco.com/go/license
- 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
