Lab Setup

Running the Monitoring Stack

Login to the Management PC and clone this repository

git clone https://github.com/munibshah/xr-netconf.git

cd monitoring
docker-compose build; docker-compose up -d

Restart the environment

docker-compose down; docker-compose build; docker-compose up -d

You should not be able to access your Chronograph at <IP address>:8888

IOS-XR Configuration

IOS XR comes with a NETCONF server that can be activated using the following commands:

netconf-yang agent ssh
netconf agent tty

ssh server v2
ssh server netconf vrf default

Next configure interfaces and enable a telemetry subscription to stream data towards the Management Client over gRPC

Interface configuration:

!
interface MgmtEth0/RP0/CPU0/0
ipv4 address 192.168.1.177 255.255.255.0
!
interface GigabitEthernet0/0/0/0
ipv4 address 192.168.10.10 255.255.255.0
!
interface GigabitEthernet0/0/0/1
ipv4 address 192.168.20.10 255.255.255.0
!

Model Telemetry Configuration:

telemetry model-driven
 destination-group DGroup1
  address-family ipv4 192.168.1.201 port 57777
   encoding self-describing-gpb
   protocol grpc no-tls
  !
 !
 sensor-group SGroupGeneric1
  sensor-path Cisco-IOS-XR-ifmgr-oper:interface-properties/data-nodes/data-node/system-view
 !
 subscription Subscription1
  sensor-group-id SGroupGeneric1 strict-timer
  sensor-group-id SGroupGeneric1 sample-interval 10000
  destination-id DGroup1

Run app.py to connect to IOSXR

Modify the environment variables located in workshop-configuration.ini

nano workshop-configuration.ini

Run the Python script to connect to IOSXR using NETCONF

source myenv/bin/activate
python3 app.py

You should see the following output

Model Telemetry

Start traffic generation on the Linux Server and Client

iperf3 server

iperf3 -sD

iperf3 client

iperf3 -c 192.168.10.1 -b 1000000 -d -t 3600 -i 10

Login to Chronograph and import the dashboard located at monitoring/chronograf/Traffic Monitoring.json

You should see the following output which confirms that IOSXR is sending telemetry towards the Management Client over gRPC
