can you provide following details?

1) Datastore dump of itm-state:dpn-endpoints

2) what kind of test you are performing

3) turn on log for org.opendaylight.genius.itm and provide that.

1）How can I get the datastore dump?

2）Execute test cases : csit/suites/netvirt/upgrade/upgrade.robot

3）Log ： karaf.log

you can use get request on REST using http://localhost:8181/restconf/config/itm-state:dpn-endpoints/ to get the datastore dump
