I am unable to reproduce this bug. What version of neutron are you using? Here are my steps, done on master:
neutron net-create test2 neutron subnet-create --name test2 test2 30.0.0.0/24 #(dhcp is enabled, I checked) neutron port-list | grep "30.0." #shows one port, as expected neutron port-delete <ID> #ID from above port-list neutron dhcp-agent-list-hosting-net test2 neutron dhcp-agent-network-remove <ID> test2 #ID from above neutron dhcp-agent-network-add <ID> test2 #Same ID neutron port-list | grep "30.0.0" #Note that the port IP address is NOT different neutron port-update --fixed-ip subnet_id=<SUBNETID>,ip_address=30.0.0.4 <PORTID> #Success There were no errors. ** Changed in: neutron Status: Incomplete => Invalid -- You received this bug notification because you are a member of Yahoo!
