[OPNFLWPLUG-831] Flow update rejected by switch generates faulty flow entry in operational DS

Mon, 27 Sep 2021 09:01:58 +0000

As far as I can tell this is only happening with Beryllium.

To reproduce:

1) Start controller Beryllium + mininet OVS 2.3+

2) Push the following sample flow:

<flow xmlns="urn:opendaylight:flow:inventory">
<strict>false</strict>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<set-field>
<vlan-match>
<vlan-id>
<vlan-id>79</vlan-id>
<vlan-id-present>true</vlan-id-present>
</vlan-id>
</vlan-match>
</set-field>
<order>1</order>
</action>
<action>
<output-action>
<output-node-connector>1</output-node-connector>
</output-action>
<order>2</order>
</action>
</apply-actions>
</instruction>
</instructions>
<table_id>0</table_id>
<id>48</id>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
<ethernet-destination>
<address>FF:FF:29:01:19:61</address>
</ethernet-destination>
<ethernet-source>
<address>00:00:00:11:23:AE</address>
</ethernet-source>
</ethernet-match>
<vlan-match>
<vlan-id>
<vlan-id>78</vlan-id>
<vlan-id-present>true</vlan-id-present>
</vlan-id>
<vlan-pcp>7</vlan-pcp>
</vlan-match>
<in-port>openflow:1:1</in-port>
</match>
<flow-name>vlan_flow</flow-name>
<priority>2</priority>
</flow>

2) Then update the flow removing the vlan-match (it will fail in ovs 2.3+):

<flow xmlns="urn:opendaylight:flow:inventory">
<strict>false</strict>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<set-field>
<vlan-match>
<vlan-id>
<vlan-id>79</vlan-id>
<vlan-id-present>true</vlan-id-present>
</vlan-id>
</vlan-match>
</set-field>
<order>1</order>
</action>
<action>
<output-action>
<output-node-connector>1</output-node-connector>
</output-action>
<order>2</order>
</action>
</apply-actions>
</instruction>
</instructions>
<table_id>0</table_id>
<id>48</id>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
<ethernet-destination>
<address>FF:FF:29:01:19:61</address>
</ethernet-destination>
<ethernet-source>
<address>00:00:00:11:23:AE</address>
</ethernet-source>
</ethernet-match>
<in-port>openflow:1:1</in-port>
</match>
<flow-name>vlan_flow</flow-name>
<priority>2</priority>
</flow>

3) Check operational and flow is still there unmodified (switch has no flow):

}
