NSO issuing show commands during provisioning

[previousqna]

A customer is currently provisioning services manually, and as part of the service design/assign process the provisioner issues various show commands to determine the best placement for the service.

We want to propose NSO to automate the provisioning.

What’s the best way to incorporate the show commands? E.g.

• Issue a show command during the service design (fastmap), parse the result and use the resulting data to design the service?
• Issue the show commands during sync-from (i.e. add them to the NED), parse the results and store them in the device model?
• Something else?

We have used both, it depends on what you are trying to do:

• During sync-from: good for HW resources. These things do not change via config changes and you always will do a sync-from when you add hardware. You will have an inventory list in the device container.

• Using reactive-fastmap: good for config resources (IPS, vlans, interface counts). These are typically checks that you want to perform using reactive fastmap as their status changes as services evolve.
