@sbyx Is this due to https://datatracker.ietf.org/doc/rfc6022/ not being present on NX-OS? https://github.com/YangModels/yang/tree/master/vendor/cisco/nx/9.2-2

sbyx commented 5 years ago

Correct, get-schema needs to be implemented for ANX to work.

i see this was closed. can i assume this was fixed?

thank you

sbyx commented 4 years ago

Not aware that it has been fixed as of now. However this issue is not related to this repo and rather is a missing feature on NX-OS and I do not see a work-around here that would be possible to implement.

anubisg1 commented 4 years ago

ok thank you. :( is a shame, this tool would have been very useful..

all right, NX-OS not supported then. thanks
