 Description   

This bug is also for: https://git.opendaylight.org/gerrit/#/c/4737/

When I create a flow with NSF FRM:

PUT http://127.0.0.1:8080/controller/nb/v2/flowprogrammer/default/node/OF/00:00:00:00:00:00:00:02/staticFlow/flow1

<flowConfig>
<installInHw>true</installInHw>
<name>flow1</name>
<node>
<id>00:00:00:00:00:00:00:02</id>
<type>OF</type>
</node>
<priority>1</priority>
<etherType>0x800</etherType>
<nwDst>10.0.0.1/32</nwDst>
<actions>OUTPUT=1</actions>
</flowConfig>

And then I delete it with:

DELETE http://127.0.0.1:8080/controller/nb/v2/flowprogrammer/default/node/OF/00:00:00:00:00:00:00:02/staticFlow/flow1

Flow is still in the switch:

odluser@odl-system-test:~\> sudo ovs-ofctl -O OpenFlow13 dump-flows s2
OFPST_FLOW reply (OF1.3) (xid=0x2):
cookie=0x0, duration=204.11s, table=0, n_packets=0, n_bytes=0, send_flow_rem priority=1,ip,nw_dst=10.0.0.1 actions=output:1

Hi Luis,

Please find the comments inline:

For OF13 mininet:

1. Start the controller using -OF13 option
2. Use the command for mininet
sudo mn --controller=remote,ip=127.0.0.1 --topo tree,3 --switch ovsk,protocols=OpenFlow13

3. PUT http://127.0.0.1:8080/controller/nb/v2/flowprogrammer/default/node/OF/00:00:00:00:00:00:00:01/staticFlow/flow1
Include the below body:
<flowConfig>
<installInHw>true</installInHw>
<name>flow1</name>
<node>
<id>00:00:00:00:00:00:00:01</id>
<type>OF</type>
</node>
<priority>1</priority>
<etherType>0x800</etherType>
<nwDst>10.0.0.1/32</nwDst>
<actions>OUTPUT=1</actions>
</flowConfig>

4. The flow gets installed on the switch
5. DELETE http://127.0.0.1:8080/controller/nb/v2/flowprogrammer/default/node/OF/00:00:00:00:00:00:00:01/staticFlow/flow1
6. The flow gets deleted from the switch

Please reverify the bug and confirm for closure.

This bug was created for a patch prepared to change Switch types and Ids in OF13 plugin.

Since this patch never saw the light so we are closing this bug.

Thanks
