Hi Anil / Openflowplugin Dev's,
I try to delete the S3 and S4 Arp flows. Actually I am passing both the
NodeID's to the delete operation. But its deleting one NodeID in Arp flow's
(randomly) .
arpFlowManager.pushFlow(new NodeId("openflow:3"),
FlowAction.REMOVE_FLOW);
arpFlowManager.pushFlow(new NodeId("openflow:4"),
FlowAction.REMOVE_FLOW);
else if(flowAction == FlowAction.REMOVE_FLOW) {
InstanceIdentifier<Flow> flowIID = InstanceIdentifier
.builder(Nodes.class)
.child(Node.class,
new
NodeKey(nodeId)).augmentation(FlowCapableNode.class)
.child(Table.class,
new
TableKey(flowBuilder.getTableId()))
.child(Flow.class,
flowBuilder.getKey())
.build();
result = mdsal.delete(LogicalDatastoreType.CONFIGURATION, flowIID);
}
Example:
mininet> dpctl dump-flows

But when I am calling NodeID's for 2 times, its Deleting both Switches Arp
flows perfectly.
arpFlowManager.pushFlow(new NodeId("openflow:3"),
FlowAction.REMOVE_FLOW);
arpFlowManager.pushFlow(new NodeId("openflow:4"),
FlowAction.REMOVE_FLOW);
arpFlowManager.pushFlow(new NodeId("openflow:3"),
FlowAction.REMOVE_FLOW);
arpFlowManager.pushFlow(new NodeId("openflow:4"),
FlowAction.REMOVE_FLOW);
Example:
mininet> dpctl dump-flows

Kindly suggest us how to delete ARP flow without duplication of 2 entries.
