Before You Begin
Check that the interface that you add to the group meets all of the necessary requirements. See How to Plan an IPMP Group.
Ensure that your role has the appropriate rights profile to perform this procedure. See Using Rights Profiles to Perform Network Configuration.
$ ipadm create-ip under-interface
$ ipadm add-ipmp -i under-interface ipmp-interface
ipmp-interface refers to the IPMP group to which you want to add the underlying interface.
The following example shows how to add the net4 interface to the IPMP group, ipmp0.
$ ipadm create-ip net4 $ ipadm add-ipmp -i net4 ipmp0 $ ipmpstat -g GROUP GROUPNAME STATE FDT INTERFACES ipmp0 ipmp0 ok 10.00s net0 net1 net4
