Few days ago, Cisco announced that it has a change of pricing for the nexus 1000V product line where it will start to provide 2 different editions of the Cisco 1000V distributed switch. The editions are called essential and advanced edition. the essential edition will be provided to the customers for free with a nominal support fee.
There are some advanced features and capabilities that are provided only in the advanced edition.
The one thing i see most promising about the essential editions is the embedding of VXLAN in the essential edition distributed switch.
Cisco has not forgotten it is existing 6,000 customers either, so they have created the following upgrade Path to their customer for the next 2.1 version.
