###Getting List of Switches

Command

$ curl -d '{"show":"switches"}' http://localhost:8080/ff/of/controller/restapi

Controller Output

20:24:33.115 [Restlet-728530265] INFO  o.f.w.j.JController$ChannelHandler - WARP REST EVENT: 
20:24:33.176 [ForkJoinPool-1-worker-1] INFO  o.f.w.j.JController$ChannelHandler - WARP REST API: INCOMING request
20:24:33.176 [ForkJoinPool-1-worker-2] INFO  o.f.w.j.restapi.RestApiTask - Incoming JSON request: ADD {"show":"switches"}
20:24:33.177 [ForkJoinPool-1-worker-1] INFO  o.f.w.j.JController$ChannelHandler - WARP INFO: Switches connected 
20:24:33.177 [ForkJoinPool-1-worker-1] INFO  o.f.w.j.JController$ChannelHandler -           | 800279BCF76
20:24:33.177 [ForkJoinPool-1-worker-1] INFO  o.f.w.j.JController$ChannelHandler -           | 10800279BCF76

So we have two switches connected: 00:00:08:00:27:9B:CF:76 01:00:08:00:27:9B:CF:76

###Installing Flow

Let's install a simple flow to the Switch '00:00:08:00:27:9B:CF:76':

Command

curl -d '{"switch":"00:00:08:00:27:9B:CF:76", "priority":"32768", "ingress-port":"1", "active":"true", "apply-actions":"output=1"}' http://localhost:8080/ff/of/controller/restapi

LINC Switch

20:28:23.243 [debug] Received message from the controller: {ofp_message,4,flow_mod,0,{ofp_flow_mod,<<0,0,0,0,0,0,0,0>>,<<0,0,0,0,0,0,0,0>>,0,add,0,0,32768,0,0,0,[],{ofp_match,[{ofp_field,openflow_basic,in_port,false,<<0,0,0,1>>,undefined}]},[{ofp_instruction_apply_actions,2,[{ofp_action_output,16,1,no_buffer}]}]}}
20:28:23.244 [debug] [FLOWMOD] Added flow entry {32768,#Ref<0.0.0.692>} with: {flow_entry,{32768,#Ref<0.0.0.1108>},32768,{ofp_match,[{ofp_field,openflow_basic,in_port,false,<<0,0,0,1>>,undefined}]},<<0,0,0,0,0,0,0,0>>,[],{1400,2103,244040},{infinity,0,0},{infinity,0,0},[{ofp_instruction_apply_actions,2,[{ofp_action_output,16,1,no_buffer}]}]}

(linc@localhost)1> linc_us4_flow:get_flow_table(0,0).
[{flow_entry,{32768,#Ref<0.0.0.692>},
             32768,
             {ofp_match,[{ofp_field,openflow_basic,in_port,false,
                                    <<0,0,0,1>>,
                                    undefined}]},
             <<0,0,0,0,0,0,0,0>>,
             [],
             {1400,2103,244040},
             {infinity,0,0},
             {infinity,0,0},
             [{ofp_instruction_apply_actions,2,
                                             [{ofp_action_output,16,1,no_buffer}]}]}]

So we can see Flow installed in the Switch #0, Table #0

Then let's install a simple Flow to the Switch '00:01:08:00:27:9B:CF:76':

Command

curl -d '{"switch":"00:01:08:00:27:9B:CF:76", "priority":"32768", "ingress-port":"2", "active":"true", "apply-actions":"output=1"}' http://localhost:8080/ff/of/controller/restapi

LINC output

(linc@localhost)3> linc_us4_flow:get_flow_table(1,0).
[{flow_entry,{32768,#Ref<0.0.0.1751>},
             32768,
             {ofp_match,[{ofp_field,openflow_basic,in_port,false,
                                    <<0,0,0,1>>,
                                    undefined}]},
             <<0,0,0,0,0,0,0,0>>,
             [],
             {1400,2356,549282},
             {infinity,0,0},
             {infinity,0,0},
             [{ofp_instruction_apply_actions,2,
                                             [{ofp_action_output,16,2,no_buffer}]}]}]

Some other REST API commands

curl -d '{"switch":"00:00:08:00:27:9B:CF:76", "priority":"32768", "ether-type":"0x0800", "dst-ip":"10.10.10.10","active":"true", "apply-actions":"output=1"}' http://localhost:8080/ff/of/controller/restapi
curl -d '{"switch":"00:01:08:00:27:9B:CF:76", "priority":"32768", "ether-type":"0x0800", "active":"true", "apply-actions":"output=1"}' http://localhost:8080/ff/of/controller/restapi

So we can see Flow installed in the Switch #1, Table #0

Deleting Flow

Command

$ curl -X DELETE -d '{"switch":"00:0C:29:BD:37:38:00:00", "priority":"32768", "ingress-port":"1", "active":"true", "apply-actions":"output=1"}' http://localhost:8080/ff/of/controller/restapi
DELETED
