can't create/update port of no IP with command line

[yalei wang]

1. when I trying to create a port without IP from a network with subnet. I specify the ip within this cmd:

#neutron --debug port-create ext_net1 --fixed-ip=""

it actually send the request with such data to server:

'{"port": {"network_id": "be7badb2-170d-46f2-9e87-480fa0a221c5", "fixed_ips": [{}], "admin_state_up": true}}'

and neutron server will parse the fixed_ips. Because currently server only support unaddress port by inputting "fixed_ips": []
When input "fixed_ips": [{}] , it will get error of "InvalidInput" from IPAM backend of neutron.

BadRequest: Invalid input for operation: IP allocation requires subnet_id or ip_address.

2. another problem is that:

#nneutron --debug port-create ext_net1 --fixed-ip "" --fixed-ip={ip_address=10.0.0.1}

when the fixed-ip list include the empty one, what kind of request should be sent to neutron server?

3. how to specify unaddress port? could we use --fixed-ips?

#neutron --debug port-create ext_net1 --fixed-ips ""

will send out the "fixed_ips": ""

#neutron --debug port-create ext_net1 --fixed-ips list=true ''
will send out "fixed_ips": [""]

The syntax that you have used is actually passing a single fixed-ip argument that is an empty string. But, what you really want is to pass an empty list. I thought there was a way to do this but I'm having trouble finding it and kevinbenton tells me in IRC that he doesn't think it can be done at the moment.

As a work-around, curl can be used to accomplish this by sending an empty list with the '{}'.

@Carl thanks! yes, now the API only support "fixed_ips": []

[Expired for python-neutronclient because there has been no activity for 60 days.]

This is also affecting me with python-neutronclient and python-openstackclient.
A curl request with "fixed_ips": [], will work.
Though with the client.

#openstack port create --network public --fixed-ip [] agtest
Expected comma separated 'key=value' pairs, but got: []

#openstack port create --network public --fixed-ip list=true agtest
Invalid keys list specified.
Valid keys are: subnet, ip-address

#neutron port-create --network public --fixed-ip []

#neutron port-create: error: argument --fixed-ip: missing value for key '[]'

#neutron port-create public --fixed-ip "" --name agtest2

Invalid input for operation: IP allocation requires subnet_id or ip_address.
