Floodlight REST Interface

We can use the browser to view Floodlight's real time information. The URL can be http://172.16.0.179:8080/ui/index.html or http://127.0.0.1:8080/ui/index.html if users access it from Controller PC.

User should pay attention to the DPID in the picture above. User needs to replace it with user's own DPID in the following tests.

curl

Use the command line tool curl for transferring data with URL syntax. It is also the tool to send Floodlight REST APIs to configure Pica8 switch flows. We can use apt-get to install it on Controller PC:

• sudo apt-get install curl

Add Flows

Here is the command to add a flow from port 1 to port 2:

• curl -d '{"switch": "67:8c:08:9e:01:82:38:26", "name":"pc1-pc2", "cookie":"0", "priority":"0", "ingress-port":"1", "active":"true", "actions":"output=2"}' http://127.0.0.1:8080/wm/staticflowentrypusher/json

We need another flow from port 2 to port 1 in order to make the ping between PC1 and PC2 work.

• curl -d '{"switch": "67:8c:08:9e:01:82:38:26", "name":"pc2-pc1", "cookie":"0", "priority":"0", "ingress-port":"2", "active":"true", "actions":"output=1"}' http://127.0.0.1:8080/wm/staticflowentrypusher/json

Now, the ping from PC1 to PC2 works.

Figure 18 – Ping Successes

We can add the same flows between port 3 and port 4 to make ping working between them.

Delete Flows

We can remove all of the flows by issuing:

• curl http://127.0.0.1:8080/wm/staticflowentrypusher/clear/67:8c:08:9e:01:82:38:26/json
