CCNP Service Provider lab 20 of 23

Assurance and automation: NETCONF, RESTCONF, SNMPv3, IPFIX and telemetry

Manage an IOS XE router through its APIs. Use NETCONF with Python and RESTCONF with curl, poll with SNMPv3, export flows with IPFIX, and build a dial-out telemetry subscription over gRPC.

Run this lab

It needs Lite: its 3 nodes are set to 3 vCPU and 5,632 MB in total. That fits the free demo too.

The scenario

Fellgate Carrier's operations team is moving away from typing commands and polling SNMP. Every router should be managed through an API and should push its own data. xe1 is the pilot, an IOS XE router with a customer on Gi2. The workstation devbox is on the management LAN.

You'll switch on each interface in turn, and use it from the workstation. On IOS XE everything below is the same on an ASR 1000.

Why IOS XE here. On this XRv image NetFlow isn't in the CLI, so this lab uses the CSR.

What you’ll practise

  • Read and change configuration over NETCONF
  • Read and change configuration over RESTCONF
  • Configure SNMPv3 with authentication and privacy
  • Export flows with Flexible NetFlow and IPFIX
  • Build a dial-out telemetry subscription, and explain gNMI dial-in

The tasks

  1. NETCONF
  2. RESTCONF
  3. SNMPv3
  4. Flexible NetFlow and IPFIX
  5. Streaming telemetry and gNMI

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder CCNP Service Provider guided labs.

  3. Open 20 - Assurance and automation - NETCONF RESTCONF SNMPv3 IPFIX and telemetry and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
