Operate BBSim

If you are testing basic functionality using BBSim no operator intervention is required.

When you enable the device in VOLTHA the simulator will:

  • activate all the configured ONUs

  • wait for the EAPOL flow for each Service that requires it and trigger the authentication state machine as soon as it’s received

  • wait for the DHCP flow for each Service that requires it and trigger the DHCP state machine as soon as it’s received

BBSimCtl

BBSim comes with a gRPC interface to control the internal state. This interface can be queried using bbsimctl (the tool can be build with make build and it’s available inside the bbsim container):

$ ./bbsimctl --help
Usage:
  bbsimctl [OPTIONS] <command>

Global Options:
  -c, --config=FILE           Location of client config file [$BBSIMCTL_CONFIG]
  -s, --server=SERVER:PORT    IP/Host and port of XOS
  -d, --debug                 Enable debug mode

Help Options:
  -h, --help                  Show this help message

Available commands:
  completion  generate shell compleition
  config      generate bbsimctl configuration
  log         set bbsim log level
  olt         OLT Commands
  onu         ONU Commands
  pon         PON Commands
  service     Service Commands

Access bbsimctl

When running a test you can check the state of each ONU using BBSimCtl.

The easiest way to use bbsimctl is to exec inside the bbsim container:

kubectl -n voltha exec -it $(kubectl -n voltha get pods -l app=bbsim -o name) -- /bin/bash

In case you prefer to run bbsimctl on your machine, it can be configured via a config file such as:

$ cat ~/.bbsim/config
apiVersion: v1
server: 127.0.0.1:50070
grpc:
  timeout: 10s

Check the ONU Status

$ bbsimctl onu list
PONPORTID    ID    PORTNO    SERIALNUMBER    OPERSTATE    INTERNALSTATE
0            1     0         BBSM00000001    up           enabled

Check the Service Status

$ bbsimctl onu services BBSM00000001

Advanced operations

In certain cases you may want to execute operations on the BBSim ONUs.

Here are the one currently supported, for more usage information use the following commands:

$ bbsimctl onu --help
Usage:
  bbsimctl [OPTIONS] onu <command>

Commands to query and manipulate ONU devices

Global Options:
  -c, --config=FILE           Location of client config file [$BBSIMCTL_CONFIG]
  -s, --server=SERVER:PORT    IP/Host and port of XOS
  -d, --debug                 Enable debug mode

Help Options:
  -h, --help                  Show this help message

Available commands:
  alarms
  auth_restart
  dhcp_restart
  flows
  get
  igmp
  list
  poweron
  services
  shutdown
  traffic_schedulers

Enable ONUs

BBSimCtl gives you the ability to control the device lifecycle, for example you can turn ONUs on and off:

$ bbsimctl onu shutdown BBSM00000001
[Status: 0] ONU BBSM00000001 successfully shut down.

$ bbsimctl onu poweron BBSM00000001
[Status: 0] ONU BBSM00000001 successfully powered on.

Autocomplete

bbsimctl comes with autocomplete, just run:

source <(bbsimctl completion bash)
