SEBA-in-a-Box with a fabric switch

The following procedure describes how to set up SEBA-in-a-Box with a physical fabric switch instead of an emulated switch.

This is the assumed topology:

Kubernetes node running OLT [ens1d1]-------[2]fabric switch[1]-----------[ens1d1]BNG/DHCP-server

1. Perform all install procedures described in the SEBA-in-a-Box installation instructions except sections Install Mininet and Load TOSCA into NEM.

2. Fabric switch bringup. To bring up the fabric switch, follow the procedure here and verify the fabric switch is discovered by onos (ssh -p 30115 onos@K8S_NODE_IP devices).

3. Enable EAPOL on linux-bridge pon0 and add the physical interface on the k8node, running PONSIM-OLT to pon1 bridge.

   $ sudo brctl addif pon1 ens1d1
   $ brctl show
   bridge name     bridge id               STP enabled     interfaces
   docker0         8000.02426df5adb1       no
   pon0            8000.52f6b00415e4       no              veth212f887a
                                                           veth84cbf365
   pon1            8000.0a580a170001       no              veth6abcdca3
                                                           ens1d1
   $ echo 8 > /tmp/pon0_group_fwd_mask
   $ sudo cp /tmp/pon0_group_fwd_mask /sys/class/net/pon0/bridge/group_fwd_mask
   

4. Modify ~/cord/helm-charts/xos-profiles/ponsim-pod/tosca/020-pod-olt.yaml. Update switch_datapath_id to your fabric-switch dpid, and switch_port and uplink to the port number of Fabric-switch to which the Kubernetes node running OLT is connected.

     olt_device:
       type: tosca.nodes.OLTDevice
       properties:
         ...
         switch_datapath_id: of:0000a82bb57111f8
         switch_port: "2"
         outer_tpid: "0x8100"
         dp_id: of:0000aabbccddeeff
         uplink: "2"
       ...
   

5. Modify ~/cord/helm-charts/xos-profiles/ponsim-pod/tosca/030-fabric.yaml. Update driver to "ofdpa3", ofId to Fabric-switch dpid, olt_port:portId to the port number of Fabric-switch to which the Kubernetes node running OLT is connected, and bng_port:portId and bngmapping:switch_port to the port number of Fabric-switch to which BNG/DHCP-server is connected.

   ...
     switch#leaf_1:
       type: tosca.nodes.Switch
       properties:
         driver: ofdpa3
         ...
         name: leaf_1
         ofId: of:0000a82bb57111f8
         routerMac: a8:2b:b5:71:11:f9
     # Setup the OLT switch port
     port#olt_port:
       type: tosca.nodes.SwitchPort
       properties:
         portId: 2
         ...
     port#bng_port:
       type: tosca.nodes.SwitchPort
       properties:
         portId: 1
         ...
     # Setup the fabric switch port where the external
     # router is connected to
     bngmapping:
       type: tosca.nodes.BNGPortMapping
       properties:
         s_tag: "any"
         switch_port: 1
         ...
   

6. Install the Modified TOSCA ponsim-pod charts and proceed to step Validating the install.
