Hi Cathy,

Thanks your response.
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.
 
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.

Hi Cathy,
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?
(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.
Neutron server returns request_ids: 
['req-47e6a39b-677a-4ce3-9976-5dfcee0ac47f']
(neutron)

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?
