[Bug 1341096] Re: neutron port-update allocates double fixed ip

 

In case someone stumbles across this like I did.

What's happening in the first case is that the client parsing is getting
confused and turns that into a list of two port updates, one specifying
a subnet_id and one specifying an ip_address. The latter ends up giving
you the IP you wanted and the first one allocates a random IP from the
subnet.

There is no way to just add an IP with the CLI without specifying the
old addresses. We don't have a concept of a patch list in the API as far
as I can tell.

This seems to be a bug in the way the neutron client breaks down the
first case into a list of two things.

For example, the following works to set three IP addresses:

neutron port-update 7521786b-6c7f-4385-b5e1-fb9565552696 --fixed-ips
type=dict
{ip_address=42.42.42.93,ip_address=42.42.42.92,ip_address=42.42.42.91}

** Changed in: neutron
       Status: Incomplete => Confirmed

** Project changed: neutron => python-neutronclient
