gNMI Adapter for NSO

This is an gNMI Adapter NSO Python package. This package adds gNMI support to NSO.

It contains a YANG data model which implements the configuration (port, security).

Build

You will also need sources from https://github.com/ConfD-Developer/gnmi-tools linked into the python directory.

Tip	cd python; ln -s ../../gnmi-tools/src/*.py .; cd ..

Configuration

Following elements can be configured (nso-gnmi-tools.yang).

• nso-gnmi-tools/port - the port the gNMI server listens on

• nso-gnmi-tools/tls/enabled - if TLS is enabled

• nso-gnmi-tools/tls/keyFile - server key file (must be configured if TLS is enabled)

• nso-gnmi-tools/tls/certFile - certificate file (must be configured if TLS is enabled)

Note	Example how to create server key and certificate file, see gnmi-tools sources, file make-keys.sh.

Run

Create NSO run dir

ncs-project create nso-gnmi`

and link this package to packages folder, e.g.

cd packages; ln -s ../../nso-gnmi-tools/; cd ..`

Note	Optionally, copy server keys and certificate file to this directory.

start nso ncs or ncs --package-with-reload

When NSO is started, the gNMI server is started as well. When nso-gnmi-tools configuration is changed, the gNMI server is restarted with the new configuration.

Usage

Use gNMI client (e.g. one present in gnmi-tools) to invoke gNMI operations against config and state data in NSO.

E.g.:

./src/confd_gnmi_client.py --insecure -o capabilities
./src/confd_gnmi_client.py --insecure -o get  --path /python-vm
./src/confd_gnmi_client.py --insecure -o subscribe -s POLL --poll-count=100  --path /python-vm --allow-aggregation

Issues and error reporting

Report only NSO package related issues. gNMI related issues should be reported in original gnmi-tools repository.

Tip	Run gNMI server standalone against NSO (./src/confd_gnmi_server -t nso) when reproducing the gNMI related issue.
