Start off by starting ponsim, make sure you do this as root as ponsim creates virtual interfaces and adds some of them into the ponmgmt bridge on the system.
sudo -s . ./env.sh ./ponsim/main.py -v
PONSIM should now be running; check this by doing the following.
sudo netstat -uteap | grep python
and you should see;
tcp6 0 0 [::]:50060 [::]:* LISTEN root 256217 19162/python
The above output also shows that PONSIM is waiting for gRPC connections which is what VOLTHA uses to talk to the simulated environment.
Next, let's check that PONSIM initialized correctly and added the correct interfaces to the ponmgmt bridge.
brctl show ponmgmt
This should return the following output:
bridge name bridge id STP enabled interfaces ponmgmt 8000.02429b8631d5 no pon1_0 veth24f4706 (<- name may vary)
At this point we are ready to launch the voltha CLI and add the simulated OLT and ONU.
./cli/main.py -L
_ _ _ ___ _ ___
__ _____| | |_| |_ __ _ / __| | |_ _|
\ V / _ \ | _| ' \/ _` | | (__| |__ | |
\_/\___/_|\__|_||_\__,_| \___|____|___|
(to exit type quit or hit Ctrl-D)
(voltha)
We have now a CLI to voltha, let's check if voltha is healthy. Enter the following at the CLI prompt.
health
which should return;
{
"state": "HEALTHY"
}
Now we can provision the PONSIM OLT and ONU in voltha. This is done in the voltha CLI.
preprovision_olt -t ponsim_olt -H 172.17.0.1:50060
This tells voltha to provision an olt of type ponsim_olt. You should see the following output.
success (device id = dece8e843be5)
The value of the device id may vary from run to run.
Next, we need to activate the OLT in voltha.
enable
which returns
activating dece8e843be5 success (logical device id = 1)
This has now activated both a ponsim olt and onu as can be seem by running the following command at the CLI.
devices
and the output should be
+--------------+------------+------+--------------+------+-------------+-------------+----------------+----------------+------------------+-------------------------+--------------------------+ | id | type | root | parent_id | vlan | admin_state | oper_status | connect_status | parent_port_no | host_and_port | proxy_address.device_id | proxy_address.channel_id | +--------------+------------+------+--------------+------+-------------+-------------+----------------+----------------+------------------+-------------------------+--------------------------+ | dece8e843be5 | ponsim_olt | True | 1 | | ENABLED | ACTIVE | REACHABLE | | 172.17.0.1:50060 | | | | 56a6fc8b859f | ponsim_onu | True | dece8e843be5 | 128 | ENABLED | ACTIVE | REACHABLE | 1 | | dece8e843be5 | 128 | +--------------+------------+------+--------------+------+-------------+-------------+----------------+----------------+------------------+-------------------------+--------------------------+
Also we can observe similar output at the REST API. To use the REST, open a new shell to the server and run the following command. Note: The port number needs to be the recorded port number from the VOLTHA installation.
curl -s http://localhost:32863/api/v1/logical_devices | jq .
and the output should be
{
"items": [
{
"datapath_id": "1",
"root_device_id": "dece8e843be5",
"switch_features": {
"auxiliary_id": 0,
"n_tables": 2,
"datapath_id": "0",
"capabilities": 15,
"n_buffers": 256
},
"id": "1",
"ports": [],
"desc": {
"dp_desc": "n/a",
"sw_desc": "simualted pon",
"hw_desc": "simualted pon",
"serial_num": "46da01fd646d4bb08140fc09b1bc4926",
"mfr_desc": "cord project"
}
}
]
}
Now that this OLT has not received any forwarding rules, it should drop all traffic. We can verify this by starting the RG emulator and observing that EAPOL authentication does not succeed. To do this start our RG docker container.
docker run --net=host --privileged --name RG -it cord/tester bash
this should land you in a command prompt that looks like
root@8358ef5cad0e:/#
and at this prompt issue the following command
/sbin/wpa_supplicant -Dwired -ipon1_128 -c /etc/wpa_supplicant/wpa_supplicant.conf
this should hang with the following output. You will need to interrupt it with Ctrl-C.
Successfully initialized wpa_supplicant eth1: Associated with 01:80:c2:00:00:03 WMM AC: Missing IEs
and in the ponsim console you should see
