= Part 1: Answer Questions
|
|
|
|
1. When ONOS activate "org.onosproject.openflow," what APPs does it activate?
|
|
|
|
It activates:
|
|
- org.onosproject.openflow
|
|
- org.onosproject.hostprovider
|
|
- org.onosproject.lldpprovider
|
|
- org.onosproject.openflow-base
|
|
- org.onosproject.optical-model
|
|
|
|
2. After we activate ONOS and run P.17 Mininet command, will H1 ping H2 successfully? Why or why not?
|
|
|
|
No, S1 and S2 will not forward packets unless `org.onosproject.fwd` is activated.
|
|
|
|
3. Which TCP port does the controller listen to the OpenFlow connection request from the switch? (Take screenshot and explain your answer.)

|
|
|
The ports that appeared only when openflow-base were enabled are:
|
|
- tcpv6 `:::6633`
|
|
- tcpv6 `:::6653`
|
|
|
|
4. In question 3, which APP enables the controller to listen on the TCP port?
|
|
|
|
`org.onosproject.openflow-base`
