[OPNFLWPLUG-63] No of active flows are not getting updated for the respective table in http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1

Mon, 27 Sep 2021 09:01:04 +0000

Steps that I tried in my setup.

Start the controller with -of13 option.
Start the mininet i.e., sudo mn --controller=remote,ip=127.0.0.1 --topo tree,2 --switch ovsk,protocols=OpenFlow13

1. PUT http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1/table/248/flow/1

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<flow xmlns="urn:opendaylight:flow:inventory">
<priority>2</priority>
<flow-name>Foo</flow-name>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
</ethernet-match>
<ipv4-destination>10.0.10.2/24</ipv4-destination>
</match>
<id>1</id>
<table_id>248</table_id>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<order>0</order>
<dec-nw-ttl/>
</action>
</apply-actions>
</instruction>
</instructions>
</flow>

2. GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1

Check the respective table (Here in this example, find "flow-node-inventory:id": 248,and see the field active flows gets updated i.e, in this case, it should be
"opendaylight-flow-table-statistics:active-flows": 1, whereas in the response it is still showing "opendaylight-flow-table-statistics:active-flows": 0

Repeat Step 2 and see if that works for now. If not proceed to the next step.

3. GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1/table/248/

see the field active flows gets updated i.e, in this case, it should be
"opendaylight-flow-table-statistics:active-flows": 1. If not, resend this request again and check the same. (Its actually works!)

4. Again, repeat the step 2 and you will see it is updated as see the field active flows gets updated i.e, in this case, it should be
"opendaylight-flow-table-statistics:active-flows": 1,

Issue: Whenever you create a table, the active flows doesn't updated at

GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1

until you send the below request

GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1/table/248/

Issue: Whenever you create a table, the active flows doesn't updated in
GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1

until you send the below request
GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1/table/248/

-------------------------------------------------------------------------------

Issue for OF10 is, the active flows doesn't gets updated even if you try to follow the above steps!

Start the mininet i.e., sudo mn --controller=remote,ip=127.0.0.1 --topo tree,2

1. PUT http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1/table/248/flow/1

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<flow xmlns="urn:opendaylight:flow:inventory">

<match>

</ethernet-type>
</ethernet-match>
<ipv4-destination>10.0.10.2/24</ipv4-destination>
</match>
<id>1</id>
<table_id>250</table_id>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<order>0</order>
<dec-nw-ttl/>
</action>
</apply-actions>
</instruction>
</instructions>
</flow>

2. GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1

Repeat Step 2 and see if that works for now. If not proceed to the next step.

3. GET http://localhost:8080/restconf/datastore/opendaylight-inventory:nodes/node/openflow:1/table/250/

4. Again, repeat the step 2 and here, you will NOT see it updated. See the field active flows gets updated or not i.e, in this case, it should be
"opendaylight-flow-table-statistics:active-flows": 1,

Let me know if you need any more information about this!
