Starting the lab

Start Model Driven Telemetry Lab.

Installing gNMIc

Login into the devbox VM inside this lab and clone the gnmic-bin repo to have the gnmic binary available inside the lab:

git clone https://github.com/hellt/gnmic-bin.git
mv gnmic-bin/gnmic ~/gnmic

IOS-XR gNMI list filtering issue in the devnetsandbox MDT lab

As of August 2020 The Model-Driven telemetry lab ships with IOS-XR 6.5.3

This XR version has some issue with the gNMI server that prevents it from accepting YANG list keys without extra quotes around key names.

Problem statement

If one would want to get the interfaces information using the openconfig models they would do this like:

gnmic -a 10.10.20.35:57400 -u admin -p Cisco123 --insecure -e JSON_IETF get --path "openconfig-interfaces:interfaces/interface"

Documentation

SR OS documentation can be fetched from this handy site: https://bit.ly/iondoc Open the 7750 section and choose the needed version.

Documents which require login are marked with "key" icon. The rest can be opened by anyone.

vSIM installation guide provides the details on how to launch virtualized SR OS and its configuration options.

Create disk images

To save on disk space the guide uses libvirt backing store technique, which allows a user to use a common disk image for every guest and each gues will have its own disk image with deltas only.
