<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Intel Clear",sans-serif">When using neutron, it is found that the behavior of admin_state_up attribute is different between port and trunks which may impact user experience. e.g. for port, Setting
admin_state_up = FALSE will set port status to “Down”, then disable the port to block send/receive packages (e.g. set port’s tap device state to down or move the port to DEAD_VLAN etc.); and for trunks,

<span lang="EN" style="font-size:10.0pt;font-family:"Intel Clear",sans-serif;color:#333333">locks the trunk
</span><span style="font-size:10.0pt;font-family:"Intel Clear",sans-serif">in that it prevents operations such as adding/removing subports, but the trunk can still operational (e,g. the trunk sub-port can still send/receive packages), and.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Intel Clear",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Intel Clear",sans-serif">So does it make sense to make a change (e.g. submit a bug or RFE) which aligns the behavior between trunk and port (e.g. setting admin_state_up= FALSE on a trunk will disable
that trunk on the vswitch - stop processing VLAN packets arriving from that VM instance) to avoid potential confusing of usage? <o:p></o:p></span></p>
