<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Thanks your response.</span><br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Another question, how to create different port-chains for different tenants, and these chains consist of the same port pair group. In my test scenario, port-pair-group created by tenant A is not
visible for tenant B.<span style="color:#1F497D"><o:p></o:p></span></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Cathy> Each port pair group has an associated tenant ID, so it belongs to a tenant, that is why it is not visible. The same tenant can have multiple chains,
eg. One for voice, one for video, one for data, and these chains can share the port pair group. But different tenants can not share the port pair group.

<tt>> Agree that it is better to clarify these points. </tt><br>
<tt>Hi Cathy,</tt><br>
<tt>I try to create multiple port-chains with the same port-pair-group, it failed. I think it is not allowed to do what you said, right?</tt><br>
<tt>(neutron) port-chain-create --flow-classifier fc --port-pair-group pg1 pc1 Port Pair Group(s) [u'17c9a0a5-a38f-4a75-834e-9aa213cd431f'] in use by Port Chain f3af530f-210a-4c51-9a02-f1835d5b1d85.</tt><br>
<tt>Neutron server returns request_ids: ['req-47e6a39b-677a-4ce3-9976-5dfcee0ac47f']</tt><br>
<tt>(neutron)</tt><br>
<br>
<tt>Cathy> when a port pair group is shared by multiple chains, these chains should be different, which means these chains should consist of different sequences of port pair groups. For example, chain 1 consists of <port-pair-group1, port-pair-group2> and chain
2 consists of "port-pair-group1, port-pair-group3, port-pair-group4>. But if the two chains are the same, i.e. they consist of the same sequence of port-pair-groups (e.g. the two chains both consist of <port-pair-group1>), then it is not allowed since it does
not make sense to create the same chain twice. Maybe your test scenario falls into the second case?</tt><br>
