Running telemetry tests on Marvell Senao Wistron switches with real hardware - mganugapati-auradine/sonic-buildimage GitHub Wiki

On the Linux box::::

export SONIC_ROOT=$(pwd)
git clone -b aurion_ptf_tests [email protected]:Auradine/aurion-sonic-mgmt.git
cd sonic-mgmt
python3 -m venv sonic-venv
source sonic-venv/bin/activate
The requirements file is present in the root directory of sonic-mgmt folder
pip install -r requirements.txt
Here is a sample ansible/inventory file
Start the ptf container 8.1 Go to sonic-mgmt folder

8.2 cd sonic-mgmt

8.3 ./start_ptf_container.sh <CONTAINER_NAME>

Here is a sample ansible/testbed.yaml file

9.1 You can determine your sonic_hwsku from: sonic-cfggen -d -v 'DEVICE_METADATA["localhost"]["hwsku"]'

9.2 t0 is short for Topology 0, which is the most basic and commonly used testbed topology in SONiC.

         +-------------------+
         |      PTF Host     |
         |  (test generator) |
         +-------------------+
            |  |  |  |  |  |
            v  v  v  v  v  v

   |             SONiC DUT            |
   |       (Your Marvell switch)      |
   +----------------------------------+

8.3 Here are the different topologies supported on SONIC.

 t0 | Single ToR + Hosts | General testing (routing, ACL, telemetry)
 t1 | Leaf-Spine (ECMP) | Route scaling, ECMP, multi-device testing
 dualtor | Redundant ToRs with MUX | High availability, switchover tests
 t0-64, t0-116 | High-density ToR | Scaling & stress testing
 t1-lag, t0-lag | Same as t0/t1, with LAGs | LAG behavior, hashing
 ptf32, ptf64 | Just PTF container sizes | Used with above

8.4 The ptf_ip comes from docker inspect ptf | grep IPAddress

The below environmental variables should be added to the .bashrc file

export ANSIBLE_LIBRARY=$SONIC_ROOT/ansible/library
export ANSIBLE_MODULE_UTILS=$SONIC_ROOT/ansible/module_utils
export ANSIBLE_CONNECTION_PLUGINS=${SONIC_ROOT}/ansible/plugins/connection
export ANSIBLE_CONFIG=${SONIC_ROOT}/ansible.cfg
export ANSIBLE_LIBRARY=${SONIC_ROOT}/ansible/library
export ANSIBLE_MODULE_UTILS=${SONIC_ROOT}/ansible/module_utils

Running a single test.

rm -rf .pytest_cache tests/_cache

cd tests (This is important)

pytest --capture=tee-sys ./radv/test_radv_run.py --inventory ./../ansible/inventory.yaml --host-pattern sonic-wistron --testbed wistron-testbed --testbed_file ./../ansible/testbed.yaml --disable_loganalyzer --skip_sanity -vvvv --mark-conditions-files ./common/plugins/conditional_mark/conditions/skip_criteria.yml

For VLAN related tests.

Please run the following commands before running the test.

sudo config vlan add 1000

sudo config vlan member add 1000 Ethernet0

sudo config interface ip add Vlan1000 192.168.0.1/24

Create topology

Start docker-sonic-mgmt container.
Create 32 vlan interfaces on the linux-server

#!/bin/bash BASE_IF="enp23s0f0np0" for i in $(seq 0 31); do SUBIF="$BASE_IF.$i" echo "Creating $SUBIF using macvlan" sudo ip link add $SUBIF link $BASE_IF type macvlan mode bridge sudo ip link set $SUBIF up done

28 of these interfaces connect to PTF --> 4 of these interface connnect to VMs. -->
