Hi,
1: Get event is same a events from GUI.
2: Have checked the debug flow basic (https://kb.juniper.net/InfoCenter/index?page=content&id=KB12208) , snoop (https://kb.juniper.net/InfoCenter/index?page=content&id=KB5411&actp=METADATA) and debug dhcp server during the issues time. Tuen on all these three debugs, reproduce the issue, stop all the debugs, snoop and check the 'get db st" .
Thanks,
Vikas
