Examples with ANNOTATION_SEGMENT_ID org.onosproject.openstacknetworking.api.Constants.ANNOTATION_SEGMENT_ID used on opensource projects

Example 1 with ANNOTATION_SEGMENT_ID

use of org.onosproject.openstacknetworking.api.Constants.ANNOTATION_SEGMENT_ID in project onos by opennetworkinglab.

the class OpenstackSwitchingHostProvider method processPortAdded.

 * createTime, segmentId and notifies to host provider.
