Gnmi on NE40E (EVE-NG)

Hello,

I'm trying to simulate a gnmi access scenario with a ne40e on eve-ng. the image has the version:

Huawei Versatile Routing Platform Software

VRP (R) software, Version 8.180 (NE40E V800R011C00SPC607B607)

I'm trying to run the capabilities command using grpc configured like this:

grpc

 #

 grpc server

  source-ip 100.116.7.1

  server-port 57777

  server enable 

But I only get the following error:

Status { code: Unknown, message: "transport error", source: None }

I'm passing username and password arguments normally in grpc request. 

User has the following confirmations set:

aaa

 local-user admin password irreversible-cipher xxxx

 local-user admin service-type http

 local-user admin user-group manage-ug

Is there a limitation on the device image or any settings missing?

Thanks,

Charles
