Brief background on Simulator:

http://ez/simulator

PreRequisite:

• x86 server reachable from controller via fabric network

Installation:

• Install docker on the test server
• docker pull the simulator agent container

$ docker pull smurugap/simulator:latest

• Launch the simulator agent container

$ echo 1024 > /proc/sys/fs/inotify/max_user_instances
$ sysctl -w net.ipv4.ip_forward=1
$ service firewalld stop
$ iptables -P FORWARD ACCEPT
$ mkdir -p /etc/simulator
$ docker run -itd --privileged -v /var/run:/var/run -v /etc/simulator:/etc/simulator --net host --name simulator-agent smurugap/simulator:latest

Scale Test Execution:

Create fabric yaml:

• Login to the container and update the fabric.yaml file

Resource Monitoring (optional):

• Launch resource monitoring service (glances) on controllers (Appformix, Contrail, JFM, JFM-Edge etal)

$ docker run -d --restart="always" -p 61208-61209:61208-61209 -e GLANCES_OPT="-w" -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host nicolargo/glances

Onboard devices:

$ python fabric.py -i fabric.yaml -o stage1

• Create simulators (-o create_simulators)
• Brownfield onboard the fabric (-o onboard_fabric)
• Assign roles based on ip-clos type (-o assign_roles)

Deleting Simulators:

$ python fabric.py -i fabric.yaml -o delete_simulators

Create workloads:

python fabric.py -i fabric.yaml -o stage2 -t 5

• Create Virtual Networks
• Create Virtual Port Groups
• Create Vlans in the VPGs Note: -t controls the no of parallel threads

Create L3 gateway:

python fabric.py -i fabric.yaml -o stage3 -t 5

• Create Logical Routers and link the VNs
• Extend the logical routers to respective physical routers

Create services:

python fabric.py -i fabric.yaml -o stage4 -t 6

• Create Security Groups and attach to VPGs
• Create Storm Control Profiles + Port Profiles and attach to VPGs

Create Unmanaged Instances:

python fabric.py -i fabric.yaml -o stage5 -t 3

• Create Routed VN, Routed VPG and LogicalRouter with Routed VN properties

Create all overlay objects:

Wrapper around all the stages

python fabric.py -i fabric.yaml -o create -t 5

Deleting overlay objects:

python fabric.py -i fabric.yaml -o delete -t 6

Deleting fabric:

python fabric.py -i fabric.yaml -o delete_fabric

Generate sflows:

To generate 1000 sampled flows with new flows every 10 minutes under test-fabric fabric

python fabric.py -i fabric.yaml -o start_sflows -c n_flows=1000,fabric=test-fabric,refresh_interval=10

Stop sflows:

To stop generating sampled flows

python fabric.py -i fabric.yaml -o stop_sflows -c fabric=test-fabric
