Catalyst 9000 License

The previous cisco licensing is divided into three following feature sets:

A.     LAN Base: It is primarily a Layer 2 feature set which offers enterprise access layer 2 switching features. It doesn’t provide any l3 functionality.

B.     IP Base: It provides the enterprise access layer 3 switching features in addition to all LAN base features. It doesn’t provide the advance layer3 features.

C.     IP Services: - It is an advance enterprise layer 3 switching features including EIGRP, OSPF, BGP, PIM and IPV6 routing protocols. It also supports all the IP base features.

The Cisco Catalyst 9000 does not use the above feature set and has its own package types. All Cisco Catalyst 9000 hardware has two software options i.e. Essentials and Advantage. Each software option includes two components, as show:

License Level	Network Stack offer (Perpetual and embedded)	Cisco DNA Software Subscription offer (Term based)
-E	Network Essentials	Cisco DNA Essentials (3, 5, or 7 years)
-A	Network Advantage	Cisco DNA Advantage (3, 5, or 7 years)

The Network Stack license is perpetual and embedded in the hardware by default and it is aligned with the hardware PID(-E/-A).

The Cisco DNA license is term-based and preselected by default to the 5-year term but can be changed to 3- or 7-year terms. Minimum of 3-year term DNA license is mandatory.

Customers will be able to upgrade the Network Stack and Cisco DNA license levels for example, -E to -A license upgrade.

Here is the comparison between three-tier packaging and Catalyst 9K new two-tier packaging.

Below features are included in the advantage and essential packages:
