[OPNFLWPLUG-713] Modifying config flow does not work if first flow creation failed

Mon, 27 Sep 2021 09:01:50 +0000

User installs a flow (e.g id=X) using the config data store and switch didn't not accept that flow because of the flow_mod error. Now user modifies the same flow in config data store to correct it, but flow does not get install on the switch.

E.g

Install following flow on the switch. This flow should fail, because of the out of range port number 65535.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<flow
xmlns="urn:opendaylight:flow:inventory">
<strict>false</strict>
<idle-timeout>0</idle-timeout>
<hard-timeout>0</hard-timeout>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<output-action>
<output-node-connector>openflow:1:65535</output-node-connector>
</output-action>
<order>3</order>
</action>
</apply-actions>
</instruction>
</instructions>
<table_id>0</table_id>
<id>1</id>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
<ethernet-destination>
<address>FF:FF:29:01:19:61</address>
</ethernet-destination>
</ethernet-match>
</match>
<flow-name>wrong-flow</flow-name>
<priority>2</priority>
</flow>

Now user modify the same flow in config data store and correct the port number

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<flow
xmlns="urn:opendaylight:flow:inventory">
<strict>false</strict>
<idle-timeout>0</idle-timeout>
<hard-timeout>0</hard-timeout>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<output-action>
<output-node-connector>openflow:1:1</output-node-connector>
</output-action>
<order>3</order>
</action>
</apply-actions>
</instruction>
</instructions>
<table_id>0</table_id>
<id>1</id>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
<ethernet-destination>
<address>FF:FF:29:01:19:61</address>
</ethernet-destination>
</ethernet-match>
</match>
<flow-name>wrong-flow</flow-name>
<priority>2</priority>
</flow>

This flow is correct and ideally it should be installed on the switch, but that's not happening.
