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.

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?
