Hi,

I'm working on this bug :

https://bugs.launchpad.net/neutron/+bug/1237807

and I'm wondering how we should address this issue, below my suggestions/thoughts

Currently when the admin_state_up of a network is set to false, the only thing which is done
is that the dhcp instance of this network is disabled/destroyed, so the dhcp port is removed
from br-int.

So should we :

1. set all ports admin_state_up to false, and let the agents (ovs) set the port as dead, 
   which is a different behavior than the dhcp which removes the port from br-int. 
  
2. do not change the admin_state_up value of ports and introduce a new field in the get_device_details
   rpc call in order to indicate that the admin_state_up of network is down and then set the port as dead ?
   So that if the admin_state_up of the network is restored all ports recover their original status.

In any case it could be a good thing to have a consistent behavior between dhcp ports and other network ports ?

Thanks in advance,
