Use this procedure for removing a physical interface. If you are using the earlier Solaris 10 3/05, refer to How to Remove a Physical Interface in Solaris 10 3/05 ONLY.
On the system with the interface to be removed, assume the Primary Administrator role or become superuser.
The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
Remove the physical interface.
# ifconfig interface down unplumb
For example, to remove the interface qfe1, you would type:
# ifconfig qfe1 down unplumb
