[OPNFLWPLUG-17] Attempt to use the 'metadata-mask' match in Flow Programming does not work

Mon, 27 Sep 2021 09:01:00 +0000

When attempting to use both metadata and metadata-mask matches from restconf, the flow is not programmed on the switch. Using just the metadata match works well.

The flow programming XML with the the defective metadata-mask match is as follows:

PUT http://192.168.4.1:8080/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/2/flow/134

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<flow xmlns="urn:opendaylight:flow:inventory">
<strict>false</strict>
<flow-name>FooXf20</flow-name>
<id>134</id>
<cookie_mask>255</cookie_mask>
<cookie>20</cookie>
<table_id>2</table_id>
<priority>2</priority>
<hard-timeout>1200</hard-timeout>
<idle-timeout>3400</idle-timeout>
<installHw>false</installHw>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<order>0</order>
<dec-nw-ttl/>
</action>
</apply-actions>
</instruction>
</instructions>
<match>
<metadata>
<metadata>12345</metadata>
<metadata-mask>//FF</metadata-mask>
</metadata>
</match>
</flow>

When reading the flow back from the controller's config space, i get the following (2 flows were programmed, so I got 2 flows back):
