How do I identify what physical ports being used for intercluster?

::*> network interface show -role intercluster
Logical Status Network Current Current Is
Vserver Interface Admin/Oper Address/Mask Node Port Home
----------- ---------- ---------- ------------------ ------------- ------- ----
vserver-name
node-01-ic up/up 10.192.18.21/24 node-01 a0a-201 true
node-02-ic up/up 10.192.18.22/24 node-02 a0a-201 true

My question is how do I find out what physical ports the lif (node-01-ic) is using for intercluster (snapmirror)? 

Thanks!
