[SFC-201] pus_nsh action is not working for sal-flow:update-flow method

Wed, 4 Jul 2018 06:23:41 +0000

1. First add the SFC classifier rule with push_nsh and set nsp, nsi fields using http://x.x.x.x:8181/restconf/operations/sal-flow:add-flow

XML file contents:
========================
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<input xmlns="urn:opendaylight:flow:service">
<barrier>false</barrier>
<node xmlns:inv="urn:opendaylight:inventory">/inv:nodes/inv:node[inv:id="openflow:6"]</node>

<installHw>false</installHw>

<ipv4-source>5.6.6.7/32</ipv4-source>
</match>

</instruction>
</instructions>

<strict>false</strict>
<table_id>5</table_id>
</input>

2. dump the flows:
cookie=0x0, duration=0s, table=5, n_packets=0, n_bytes=0, priority=32768,ip,nw_src=5.6.6.7 actions=push_nsh,set_field:3->nsi,set_field:0xa->nsp,goto_table:10

3. Now update the this flow with different NSP and NSI using below update-flow method.
http://172.24.12.217:8181/restconf/operations/sal-flow:update-flow

xml file :contents
====================
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

</updated-flow>
</input>

4. ODL is throwing the error:
Failed to process interface org.opendaylight.yang.gen.v1.urn.opendaylight.openflowplugin.extension.nicira.action.rev140714.update.flow.input.updated.flow.instructions.instruction.instruction.apply.actions._case.apply.actions.action.action.NxActionPushNshRpcUpdateFlowUpdatedApplyActionsCase for version 4

even though flow get added, dump flows does not shows the push_nsh action:
cookie=0x0, duration=0s, table=5, n_packets=0, n_bytes=0, priority=32768,ip,nw_src=5.6.6.7 actions=set_field:3->nsi,set_field:0x28->nsp,goto_table:10

5.Is this behavior expected one?
Please correct me if the steps are wrong.

NOTE:Same behavior is for the pop_nsh action.
