Any NED supports the features that have been used by previous customers and POCs for that NED. No customer should expect any NED to be "complete" and cover all possible use cases for the managed device. NEDs are developed incrementally as and when needed. There is also no NED roadmap. This is possible because of the extremely short turnaround times for NEDs and NED enhancements. This is beneficial to everyone. From a customer perspective they will get the NEDs and NED features that they require for when they need them. The question "does NED x support feature y or OS version x?" becomes moot - the answer is yes - if it is required then it will, provided that the customer has purchased the NED, that they have a current support agreement, that the request is for "normal" use of the managed device (i.e. a configuration use case that is not extremely customer specific), and that the NED team can access devices for test purposes, which may require access to devices in the customer's network.
The normal SWSS contract covers NEDs purchased from the price list, and entitles access to all future versions of the NEDs. They can request enhancements to the NEDs, via the account team, as per the NED request process specified in the NED index slides on DevNet and Field Portal, and we will deliver these at no additional cost, provided that the enhancements represent reasonably mainstream use of the managed devices, and can be added without adverse impact on other customers. NED enhancements will normally be delivered within 2-6 weeks after we have received required data regarding the configuration use cases and commands, depending on the volume and complexity of the enhancements, and also sometimes on being able to access the customer¹s devices in the cases where device/OS versions and features are not available in our labs.
