Test Case: Multicast/IGMP

• PONSIM OLT and ONUs registered as ACTIVE in VOLTHA
• RG having obtained an ipv4 addr from Onos DHCP server

Pass scenario:

1. Onos cli type "flows"
   1. That should return a certain number of flowRuleCount such as "flowRuleCount=8"
2. Onos cli type "groups"
   1. That should return a certain number for groupCount such as "groupCount=1"
3. Send an IGMP packet from the RG up to the ONU
   1. Type  "igmp.py -j -i pon1_128 -m 229.0.0.1"
   2. Should get back
      " .
      Sent 1 packets."  ( over two lines )
4. Onos cli type "groups"
   1. GroupCount should have increased by one
5. Onos cli type "flows -s"
   1. Check output for added flow bearing "229.0.0.1"
6. Check whether we find this state in the logical device in VOLTHA.

1. 1. Type " logical_device
      flows" ( two commands )
      1. In flow table look for flow bearing "229.0.0.1"
2. Back to the physical device level
   1. Type "devices"
   2. Type "device <device Id> that sent the packet i.e. pon_128
   3. Type "flows"
      1. In flow table look for flow bearing "229.0.0.1"
3. Send packet down NNI port towards RG
   1.  sudo scapy
      mc = Ether(src="00:00:00:00:00:01")/Dot1Q(vlan=<vlanId>)/IP(dst="229.0.0.1", proto=17) sendp(mc, iface="pon1_0")
   2. On RG container we type  "tcpdump -nei pon1_128"
      1. We should see packet bearing 229.0.0.1

Acceptance Criteria:

• Should demonstrate all pass and fail scenarios
• Log files should be attached to Jenkins artifacts
• Test should be triggered from Gerrit
