# ONOS
## Course
- What's different between Control plane vs management plant?
- Can controller route the overlay network?
## Lab 1
Start ONOS Server in localhost
```shell
cd $ONOS_ROOT
bazel run onos-local -- clean debug
# option 'clean' to delete all previous running status
# option 'debug' to enable remote debugging (port 5005)
```
ONOS CLI
```shell
cd $ONOS_ROOT
tools/test/bin/onos localhost
```
ONOS GUI
http://localhost:8181/onos/ui/
onos/rocks
```shell
apps -a -s # Show activated apps only
app activate org.onosproject.openflow
app activate org.onosproject.fwd
app activate org.onosproject.proxyarp
# app activate org.onosproject.drivers.ovsdb
app deactivate <name> # deactivate onos app
```
Create linear topology
```shell
sudo mn -c #clean and exit
sudo mn --topo=linear,3 --controller=remote,127.0.0.1:6653
sudo mn --topo=linear,3 --switch=ovs,protocols=OpenFlow13 --controller=remote,127.0.0.1:6653
```
```shell
pingall
dump
```
Custom Topology
```python
from mininet.topo import Topo
class MyTopo( Topo ):
def __init__( self ):
Topo.__init__( self )
# Add hosts
h1 = self.addHost( 'h1' )
h2 = self.addHost( 'h2' )
# Add switches
s1 = self.addSwitch( 's1' )
# Add links
self.addLink( h1, s1 )
self.addLink( h2, s1 )
topos = { 'mytopo': MyTopo }
```
```shell
sudo mn --custom=sample.py --topo=mytopo --controller=remote,ip=127.0.0.1,port=6653
```
1. When activating "org.onosproject.openflow", what are the APPs which also be activated?
https://wiki.onosproject.org/display/ONOS/Managing+ONOS+applications
2. Can H1 ping H2 successfully? Why or why not?
```shell
app activate org.onosproject.fwd # H1 ping H2 ping successful
app dectivate org.onosproject.fwd # H1 ping H2 ping failed
```
3. Which TCP Port the controller listens for the Openflow connection request from the switch?
4. In question 3, which App enables the control to listen on the TCP port?
https://wiki.onosproject.org/display/ONOS/Requirements
```
ONOS requires the following ports to be open, in order to make the corresponding functionalities available:
8181 for REST API and GUI
8101 to access the ONOS CLI
9876 for intra-cluster communication (communication between target machines)
6653 optional, for OpenFlow
6640 optional, for OVSDB
```
## Lab 2
```shell
sudo apt update
sudo apt install wireshark
sudo wireshark # choosing the loopback interface
```
```shell
sudo mn --controller=remote,127.0.0.1:6653
> h1 ping h2 -c 5

To use dhcpd inside mininet host properly, you should modify
AppArmor settings (only need to be done for the first time)
```shell
sudo apt update && sudo apt install -y isc-dhcp-server
# server
sudo ln -s /etc/apparmor.d/usr.sbin.dhcpd /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.dhcpd
# client
sudo /etc/init.d/apparmor stop
sudo sed -i '30i /var/lib/dhcp{,3}/dhcpclient* lrw,' /etc/apparmor.d/sbin.dhclient
sudo /etc/init.d/apparmor start
```
1. Configure a DHCP server location
2. Install flow rules to Packet-in DHCP packets
3. Compute path between a DHCP client and the DHCP application
4. Install flow rules to forward DHCP packets via unicast
