CURL with an drop "apply_actions"

sbotkine — Tue, 25 Mar 2014 14:43:49 GMT

Hello,

I don't know how to add "drop" as an apply_actions:

curl --noproxy 130.223.16.128 --header 'X-Auth-Token: a97daad3ea18489eb38c8c6a7ae5236e' --header "Accept: application/json" --header "Content-type: application/json" --fail -ksSfL -X POST -d '{"flow":{"priority":20,"table_id":100,"idle_timeout":60,"match":[{"eth_type":"arp"}],"instructions":[{"apply_actions":[{"drop"}]}]}}' --url https://130.223.16.128:8443/sdn/v2.0/of/datapaths/00:14:f0:92:1c:21:fa:c0/flows

I obtained: curl: (22) The requested URL returned error: 400 Bad Request

Do you know how to do that ?

Hi sbotkine,

The way to accomplish a drop is with an empty list of actions. That's the way it's accomplished in the OpenFlow spec, so that's how it's accomplished through the controller's REST API as well.

Hi,

as per the answer already marked as the solution of this thread, please just leave the apply_action section empty.

This will drop packets:

OK, I worked it out.

To add or remove a drop action for specific IP or IP range>

curl --header "X-Auth-Token:$AUTH_TOKEN" -H "Content-Type:application/json" -ksS --url "https://$CONTROLER_IP:8443/sdn/v2.0/of/datapaths/$SW_DPID/flows" -d "{\"flow\": {\"priority\": 20100,\"table_id\":100,\"idle_timeout\": 60000,\"match\": [{\"ipv4_dst\":\"10.0.0.120\",\"mask\":\"255.255.255.255\"},{\"eth_type\": \"ipv4\"}]}}" --request POST

curl --header "X-Auth-Token:$AUTH_TOKEN" -H "Content-Type:application/json" -ksS --url "https://$CONTROLER_IP:8443/sdn/v2.0/of/datapaths/$SW_DPID0/flows" -d "{\"flow\": {\"priority\": 20100,\"table_id\":100,\"idle_timeout\": 60000,\"match\": [{\"ipv4_dst\":\"10.1.0.120\",\"mask\":\"255.255.255.255\"},{\"eth_type\": \"ipv4\"}]}}" --request DELETE
