Description (partial)

Preconfig committed under a nV Optical controller can be lost if committed at the same time as transponder or muxponder config.

For example, committing the following config in a single commit is unlikely to have the desired effect:

nv satellite 100
  type ons15454-m6
  transponder 100g 3/0/2
controller preconfigure Optics100/3/0/1
  port-mode ethernet

The likely behaviour is that the 'port-mode' config is lost from the system.

It is possible to see this behaviour in any scenario that causes transponder/muxponder config to be committed along with controller preconfig, for instance during config rollback.


Seen usually when configuring a transponder or muxponder, and (in the same config commit) preconfiguring a controller that's part of that transponder or muxponder.

Only preconfig is impacted; without the 'preconfig' keyword the problem is not seen.

There is no impact to preconfig that's already in the system (i.e. listed in 'show running'), when the transponder/muxponder is configured.

Can also be seen when configuring a satellite's type (and preconfiguring a controller), if the satellite has existing transponder/muxponder configuration.
