Bug Resolved Done Unassigned Shigeru Yasuda Mon, 28 Apr 2014 06:01:36 +0000 Thu, 3 May 2018 15:45:10 +0000 Thu, 8 May 2014 02:10:57 +0000 unspecified VTN Manager 0 2 <p>This issue was caused by a bug of old version of Open vSwitch.</p> <p>Old versoin of Open vSwitch (eg. 1.4.6) has a bug that it may clear OFPFW_DL_VLAN_PCP bit in FLOW_REMOVED message incorrectly. If OFPFW_DL_VLAN_PCP bit is not set in FLOW_REMOVED message, OpenFlow protocol plugin set DL_VLAN_PR match field into SAL Flow converted from FLOW_REMOVED. VTN Manager can not remove such SAL flow from flow database because current VTN Manager never set DL_VLAN_PR match field into a flow entry.</p> <p>Although this is not caused by a bug of VTN Manager, I decided to add workaround for this OVS bug.</p> <p>I close this bug because patch was merged.</p> <p> <a href="https://git.opendaylight.org/gerrit/6442" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/6442</a> (master)<br/> <a href="https://git.opendaylight.org/gerrit/6490" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/6490</a> (stable/hydrogen)</p> Development External issue ID 857 External issue URL Rank 0|i02t2f:
